Is hair coloring harmful ?: professional opinion

Added: 12/31/2013 10:30 AM

Initially, confusion in opinions and conclusions arises from a wide variety of hair dyes. In fact, paint is a chemically active cosmetic product, its composition directly depends on its type and desired result, and this composition can vary considerably, including both quite benign and mild substances, and aggressive components. In general, speaking of the paint, you always need to consider what kind of tool in question. Henna is a paint, hydrogen peroxide is a paint, and lightly tinted foam is also a paint. All of them at the same time have a different composition and different effects on the hair.

All hair dyes can be divided into 3 types:

• Resistant. Resistant and semi-resistant hair-dyes contain components such as hydrogen peroxide and ammonia - this is the reason for the depth of the impact of the product on the hair. These are chemically active substances that “uncover” hair and replace a person’s own pigment with a dye pigment. Resistant and semi-resistant paints are suitable for painting gray hair, they do not wash off - except they can fade with time. You can get rid of them only by dyeing your hair in a different color or growing it. The content of ammonia, hydrogen peroxide and other aggressive chemicals in semi-dyed hair dyes is reduced, due to which they are considered more benign and less able to radically change the hair color.

• Shading. Shading means do not interfere with the structure of the hair: they create a film on the surface of the hair - the color that you chose. Tint shampoos, foams and paints are very unstable: it is enough to wash your hair 4-6 times - and there will be no trace of the artificial color. They can not drastically change the color of hair - only slightly shade your own. For example, if you have light blond hair, you can make them more golden or slightly reddish with a tint tool, darken light brown a little. Sedinu such funds do not paint.

• Natural. Natural dyes - henna and basma - also do not damage the hair structure, but create an indelible film on its surface. The main advantage of natural paints is their harmlessness and incredible durability (it is almost impossible to remove henna - and it is also quite difficult to paint over), the main drawback is the limited set of shades (red, red-brown, black) and the unpredictability of the result. Natural paints can behave very capricious and even insidious, giving a different effect under the same conditions. On gray hair often look too bright (for example, henna can give an orange color).

Speaking about the dangers of hair dye, we primarily mean resistant and semi-resistant products, because the tint and natural dyes do not affect the hair at a deep level, they simply envelop it with color.

What is the harm of hair dye?

The main health hazards - hair and the whole body - are aggressive chemical components. Here are the negative consequences you face when dyeing your hair:

Violation of the hair structure. Penetration into the hair structure and removal of natural pigment cannot pass unnoticed by the hair: they lose not only the color, but also a number of nutrients, their integrity is disturbed. The hair becomes drier, brittle, splits stronger at the tips. In modern professional paints this effect is partially compensated by the caring elements, but this does not change the essence. Dyed hair is by definition less healthy and strong than natural colored hair. If you dye your hair all the time, they can become more sparse, weak and lose their shine for a long time or forever.

Allergic reaction. An allergic reaction to one of the many chemicals contained in the paint or a combination of them is very possible. Therefore, manufacturers of paints always strongly recommend before using paint to do a test test on the crook of the arm. Do not ignore this tip: an allergic reaction to paint can be quite severe!

The impact of "chemistry" on the body. Active chemicals can harm not only your hair, but the entire body. First and foremost, the scalp may suffer (unsuccessful staining is a risk factor for various problems like seborrhea, hair loss, dandruff). It is also possible the occurrence of a hidden allergic reaction, manifested indirectly. In addition, there is a suspicion that exposure to the chemical components of paint in the long term, with frequent staining, can accumulate and result in negative health effects - for example, increase the risk of developing oncological diseases.

Should I dye my hair? It will be healthier, of course, not to dye your hair, especially since naturalness is now in fashion. On the other hand, it is clear that the possible negative effects are perceived by many as a small sacrifice laid on the altar of beauty, so all the same they will dye their hair - and not only women. And few people are ready to put up with gray hair. Therefore, it is important to follow a few simple rules to minimize damage. First: for painting, use only high quality paints, preferably professional ones. Second: if it is possible, if you do not need to paint over gray hair, choose sparing paints with a minimum content of ammonia. Third: properly care for your hair after dyeing, use special regenerating agents, if you notice any negative effects after dyeing (itching, hair loss, feeling unwell), try another remedy or discard the paint altogether.

Popupermanent (non-ammonia) dyes: is it harmful for hair?

In this form of dyes, both direct and colorless molecules are often used, which appear as color only after they enter the hair cortex. This type of dyes are made on the basis of a cream, gel or oil. Usually activated with the help of emulsions 1.5-4%, but can be used with a higher percentage of oxidation of 6-9%. Thus, semi-permanent paints can dye not only tone to tone, but also lighten by 2-3 tones when mixed with a high percentage of oxide.

Dark shades of semi-permanent dyes are rather resistant than direct dyes, but light shades are washed away after 5-15 hair washes. All, of course, will depend on how porous hair - paint from damaged hair is washed off quickly.

You should not be fooled by reading the cherished word “ammonia-free” on the package - there are really no ammonia in the composition, but there are other alkaline elements, its substitutes, they are called ammines (ethanolamine, monoethanolamine, demyethanolamine, etc.). Amines are much more expensive than ammonia, because they have a milder effect on the hair structure. When dyeing hair semi-permanent means slowly open the cuticle, through the scaly layer reach the cortex, where they create connections. After that, the dye molecules exhibit color and are fixed due to expansion in volume.

When using ammonia-free dyes, the pH of the hair and skin can increase to 7-9. That is why you should definitely use after dyeing special shampoos and conditioners with an acidic pH. This will allow:

1. normalize the pH balance of hair and skin
2. stabilize color molecule
3. stop alkaline processes
4. close the cuticle and add extra shine to the hair
   

This item - washing off the paint with shampoo with an acidic pH - is very important and must be present in high-quality hair dye. Even healthy and dense hair can literally maim, not to mention thin and damaged.

Permanent dyes: what is harmful in them?

This type of dyes allows you to cope with even the most difficult tasks - from the darkest shades and precise hitting the tone to graying gray and brightening to 4 tones. Ammonia is present in the composition of the agents, as a rule, not more than 15% in a 25% aqueous solution. It has a cream base and works with oxidants of any saturation.

Ammonia paint cuticle opens much faster than ammonia free paint - no more than 10 minutes. A further scheme of fixing and manifestation of the color molecule corresponds to the action of semi-permanent paint.

Such a dye will be washed off in different ways - everything again depends on the chosen color and degree of hair porosity. Permanent dyes have an alkaline pH of 11.

These dyes saturated with useful components do not provide a therapeutic effect on the hair for one simple reason - such care is simply not enough for the strong effect of ammonia. The most commonly indicated on the packaging of paint vitamins, oils and minerals are nothing more than a marketing ploy. Their concentration is so small that it does not withstand coloring and literally burns on the hair. Especially when high percentages of oxidizing agents are used. Unfortunately, it is impossible to put more active ingredients into such paints, because it will interfere with the hair dyeing process (gray hair will not be taken or there will be poor clarification).

Hair itself suggests itself: then why add these caring components at all if they don’t give a positive result?

The fact is that there are 3 reasons:

1. to attract the attention of the buyer in red words
2. reduce the effects of ammonia and create a cosmetic effect on the hair
3. sometimes used to enhance shine colored hair

In the final third part, we will tell you whether it is safe to dye your hair with an ammonia dye, or its negative impact on the hair structure is nothing more than a myth.

Safe hair coloring: tips from professionals

Many colorists say that coloring (professional, of course) not only does not harm the hair, but also restores their health. Is this true, or is it another marketing move?

Professionals confirm: safe staining exists, and there are different techniques that help to achieve the desired result. We present the rating from the experts: six safest ways to change the tone of hair!

First place - coloring with tinting shampoo

Toning shampoo is the easiest and safest way to refresh hair color or change it by 1-2 tones, it is not capable of anything more. With it you can try on extraordinary shades, if the soul asks for paints. As a part of the tinting shampoo there is neither hydrogen peroxide, nor ammonia, therefore it paints only the surface of the hair and does not penetrate into the core at all. Therefore, the dye is quickly washed out, a maximum of a week.

Toning shampoos have contraindications: you can’t use them if you have chemical hair dyed hair, you have recently lightened curls or individual strands, or permed. The result, firstly, can be unpredictable, and secondly, to wash the dye will be a daunting task, in some cases even insoluble. And consider another nuance: even after the shade has disappeared, it is better to abstain from chemical staining for 2-3 weeks, so that the residual pigments do not react with the paint.

Second place - henna staining

The method of coloring, known even to our grandmothers, is still very much alive. The truth is now there are so many types of organic henna that you can pick out any shade and not be limited to the standard red.

The beauty of henna is that it is a completely natural ingredient. In its composition there are oils, tannins and resins, they are perfectly integrated into the structure of the hair, and even ennoble it - strengthen, nourish, restore, smooth out the roughness.

Henna is poorly washed out of hair, so if you want to switch to regular dyes, it will take time: chemical dyes do not fall on top of henna.

Third place - toning

Toning is a way to refresh the color or change it depending on the chosen coloring option. And the hair color can be given to almost any (except, of course, radical changes - for example, from brunette to blonde).

Toning does not help to paint over the roots, if your natural color is very different from the colored mass of hair, and it does not do very well with gray hair: initially gray hair will absorb pigment, but it will be washed off very quickly.

• Toning is ammonia-free and transparent. In non-ammonium toning, a gentle pigment is used. Its composition gently envelops the hair, giving it the desired shade and dazzling shine. In transparent tinting used light transparent gels. They give shine to hair, and herbal extracts in the composition of preparations nourish the strands and restore their structure.

4th place - bio lamination

Biolamination is also called "manicure" for hair. This is because after the procedure you get an instant, though short-term effect - shiny Hollywood strands and a delicate shade. The process uses dyes based on natural nutrients - for example, beeswax.

You can make color and colorless lamination. In the composition of preparations for color lamination in addition to the conductor (the same beeswax) there are dyes based on natural ingredients. They envelop the surface of the hair, in a company with nutrients tighten, give the hairstyle volume and temporary shade. The truth with biolamination is that you do not change the image radically, it rather enhances and brightens the shade you already have.

In the process of colorless lamination, the hair is simply given shine and volume.

The result of biolamination lasts a maximum of two weeks (the same color will hold). Another disadvantage: biolamination, like lamination, cannot be done on thin hair. They just droop. In addition, under the film, which covers the hair, will not be able to penetrate the nutrients from the balms and masks. And it is useless to use these products during the period of bio-lamination. By the way, after the biolamination procedure, your hair will become absolutely straight, so they can not be screwed on a curling iron or hair curlers, and set as you wish. Strands just do not succumb.

Fifth place - bio coloring

Bio-staining refers to a method that uses ammonia-free dyes. In the process, you can give your hair the desired shade (and even radically change the color) without damaging their structure.

This coloring is not suitable for gray hair, as it does not paint over gray hair one hundred percent.

• Ammonia is not a conductor in ammonia free dye, as you might guess, but oils, for example. Dye as it envelops the surface of the hair, not penetrating into the cortex.

Sixth place - sparing ammonia staining

Experts claim that modern ammonia dyes are not as dangerous as we used to think. Ammonia is introduced into the paint in order to raise the hair scales more strongly, allowing the pigment to penetrate deeper. This injured hair earlier, but in modern methods of dyeing it is provided the application of special means that lower the scales back and fix them in this position.

Naturally, such a procedure can only be carried out in the salon, where strictly professional dyes are used. In the most modern ammonia, the concentration of harmful substances is reduced, which destroy the structure and the cortex of the hair. Therefore, these dyes are safe for the health of the strands and help to paint even one hundred percent gray hair.

Types of staining and their influence

Absolutely harmless methods of changing the natural natural hair color are only folk methods of toning or lightening by 1-2 tones. The use of any chemical paints, even sparing, sooner or later will have a negative impact on the state of hair.

Here is what damage is done to hair when:

• lightening - this procedure is simply deadly for the hair, and the more tones it leaves, the more damaged the hair structure is,
• highlighting - this type of coloring implies pre-clarification of the strands with the composition containing peroxide and ammonia,
• persistent dyeing - in addition to ammonia, lead and other harmful components are present in dyes for dark hair,
• staining with ammonia-free paints is a trick for manufacturers, in which ammonia is merely replaced by a less aggressive chemical compound, which also loosens the keratin layer,
• tinting - tint balms are also not completely safe, with frequent use, they dry out a lot of hair.

In fact there are no safe paints. Therefore, it is not worth experimenting with hair color unnecessarily. Unless you buy for this purpose a water-based spray that keeps exactly until the next wash.

When it is time to be painted

The question of how often you can dye your hair without harm to them is difficult to answer unambiguously. It depends on the type of paint chosen and other factors. Radically change hair color at any time. But it is necessary to objectively evaluate the state of the hair.

If the hair is brittle, dried, strongly whipped at the ends, then it is wiser to defer the coloring for a couple of weeks, during which you will intensively feed them with masks.

Sometimes coloring is carried out in several stages. Especially if you need to go from dark to very light color. If you do it right away, you can spoil the hair so much that only a short haircut will save the situation.

Not always in a transitional period the hairstyle looks attractive, but it is better to put up with it and suffer a few weeks.

Persistent paints

Repeated staining with resistant paints is recommended once every 4-6 weeks. And no matter how much you want to paint before, you should not do this. The hair and so after a strong impact can not fully recover. And if you actively destroy it additionally, then not only the hair can suffer, but also the skin, which is also irritated with each coloring.

Sometimes the hair grows too quickly, and the gray roots become noticeable after a couple of weeks. In this case, you should regularly use a tonic or spray to paint the roots. This will reduce the damage caused by the hair and will allow to postpone the next painting even for several weeks.

To gray hair was less noticeable with a large number of it, it is wise to approach the choice of colors. With too dark or bright, it will obviously contrast and only emphasize your age. But light brown, beige, coffee, wheat tones perfectly mask it and do not require such frequent correction.

Ammonia paint

Even professional non-ammonia paints still damage the hair. But their main advantage is that they can be taken for resistant toning. In this case, the minimum percentage of oxidizing agent (1.5-3%) is used, and natural oils and other useful additives are often present in the composition of the dye itself. Such paints can be used about once a month without much harm to the hair.

The best manufacturers have proven themselves: "Capus", "L'Oreal", "Matrix". You can buy their products online or in specialized stores. The oxidizer is sold separately. How much it needs to be added to the paint, and what percentage to use, is described in detail in the instructions in each package.

Household non-ammonia paints, which are sold in regular stores, in fact, are not much different from persistent. Is that their composition softened oils and vitamin supplements, and the percentage of ammonia is lower than usual.

The fact that the paint is unsafe points and a ban on their use during pregnancy and lactation. Therefore, it is advisable to use them as rarely as possible - once every 4-6 weeks.

At the same time, keep in mind that the pigment from non-ammonia paints does not penetrate deeply and is washed out faster, therefore it is better to wash your head with shampoos for dyed hair, protecting the brightness of the color.

Sparing paints and high-quality home-use shampoos are offered by companies such as Estelle, Garnier, and Pallet.

Toning, unlike staining, is a physical process. Tint balm wraps hairs thin film that contains pigment. With each wash it becomes thinner and the color fades. Theoretically, the tonic is harmless, but in fact it prevents the hair from breathing normally, clogs the pores and increases the density of the rod. As a result, if the hair is tinted too often with tonic hair, it loses its elasticity and begins to break.

On average, tonic is washed out 6-8 times, qualitative - 8-10. Given the fact that it is desirable to wash your hair every other day, it is enough to use this tool 1-2 times a month. But it is on pre-painted dyed hair, when you only need to maintain the intensity of the shade.

If the tonic is applied to the natural hair color, the keratin layer is not loosened, and the pigment is washed out faster. In this case, you can use the tonic every 7-10 days.

Remember that if you keep it longer than recommended by the manufacturer, the color will not become brighter. But the skin can get irritated - yet the tonic contains many chemical components. So the instruction should be carefully studied and comply strictly.

Dyes of direct action: their harm and benefits for hair

Direct acting dyes are toning shampoos, balms, crayons, pastes and mascaras. Such agents contain direct pigments that are already ready for use and do not need oxidizing agents to appear on the hair. They are easy to use at home, because for painting you will not need to know the special technology of applying or preparing paint. These funds are applied directly to the hair with a brush, sponge, spray, etc. By the way, henna and basma also belong to direct dyes, despite the fact that they are of plant origin.

The pigment of such a dye is attached to the hair cuticle due to adhesion, or, more simply, adhesion. Dyeing direct exposure will not be persistent, usually the color is washed off after several washes of hair (minimum exposure time is 1 day, maximum time is 2 months).

Are direct exposure dyes safe?

This type of dyes has an acidic pH level, so for the scalp such products are completely harmless, because human skin and hair have a low pH of 4.5 to 5.5. An important requirement for direct-acting dyes is their international certification and quality safe ingredients in the composition. Do not buy hair products from unknown brands to avoid health problems.

Also, professionals do not recommend to get involved in coloring crayons: due to the high content of lime, which takes away all the moisture from the hair, crayons, with frequent use, can dry out hair, make it brittle and fragile. The same can happen if you use henna from unknown Indian masters. Therefore, if you belong to lovers of organic hair coloring, we advise you to use only high-quality and certified henna and basma.

Frequent staining - harm or norm?

The answer to this question depends on the choice of coloring agents and the condition of the hair. The use of chemical dyes is harmful due to the presence of such components as:

And if there are more, the paint is more stable and the paint is more intense.

Ammonia can destroy their structure from the inside and outside. In this case, as well as with allergies, the desired color can be obtained by dyeing the hair with natural dyes.

Safe natural plant dyes

Natural dyes have long been used to dye, strengthen the roots and enhance hair growth.

You can safely use them often as you see fit. The most intense natural dyes are:

• henna - chopped dried leaves of alkanes,
• Basma - indigo leaf powder.

Using juice, decoctions and infusions of plants can be obtained different color and shade: light golden, as well as brown and black.

Excellent natural dyes:

• onion peel,
• nettle root,
• chamomile flowers
• cinnamon,
• rhubarb,
• green rind and walnut leaves,
• Linden twigs and flowers.

In addition, to create darker shades use:

• oak bark,
• tea extract,
• decoction of tea with cocoa powder or instant coffee.

Natural dyes are harmless and cheap, but the color of the hair obtained with their help is not sustainable. To maintain the effect they are used regularly in the form of rinsing.

It should be noted that after the systematic use of natural dyes, the effect of chemical dyes can be weakened. Nevertheless, they are successfully used and get a luxurious effect.

And here is another article that may come in handy. If you want your hair to grow faster and thicker - nicotinic acid will help you.

Professional paints

Everything dyes with ammonia (permanent) or with hydrogen peroxide in the base, give persistent staining of the whole head of hair and tinting of the roots, but are harmful. You can use them no more than once in 1.5 - 2 months.

Subject to the instructions for use, in particular the time of exposure, the hair will not be significantly harmed. Such dyes paint over gray hair well. Especially popular and most harmless are professional Matrix hair dyes.

The use of harmless paints with a minimum content of peroxide and ammonia gives less resistant staining. it soft tints.

It is quite enough and safe to apply them once a month, maintaining bright rich colors.

More often, namely once in two weeks, you can tint hairusing special toning tools:

Of course, this is not a persistent coloration and changes the color to just one or two tones.

Frequent discoloration

Lightening is the most aggressive effect. The natural pigment is almost completely destroyed, the hair loses its silkiness and shine. Therefore, it is desirable to lighten only once or twice a year.

Then we lighten only growing roots, but not earlier than in 3-4 weeks. Bleached hair need special care:

• soft shampoos
• moisturizing masks,
• retaining moisture conditioners.

Therefore, you should think carefully and decide whether you need it?

As an exception - hair oily and heavy. Brightening can improve them. make it easier and more voluminous. At the same time, the state of the roots does not deteriorate, the growth increases, but even in this case it is not worth to abuse the procedure of aggressive clarification.

How often can you highlight

Individual strands, painted with a distinctive color from the main mass, are attractive and effective on hair of different lengths. Highlighting, like dyeing hair in two colors or more, gives your hair extraordinary brightness, perfectly hides her gray hair.

But hair grow back, and the procedure requires a stable update. And this negatively affects their condition.

Master professionals help out:

• hair condition is assessed,
• paint and color are selected,
• necessary care and recovery in case of damage.

• Highlights black hair looks especially extravagant. Execution is available only to masters, as not only the arrangement but also the frequency of the strands is thought out,
• Dark brown hair gently enliven by highlighting with light or darker strands, but without contrasts,
• Brown hair - This is an intermediate shade in color and is livened up with light and dark strands. These are honey, golden, red, red.
• Blondes also make highlighting, and very effective. Strands slightly lighter than the bulk add shine, life and volume:
  • for ashy blondes, shades from a cold palette are suitable,
  • for natural blondes - dark, nut and caramel colors.

Highlighting for fair-haired and dark-haired girls can be done as the dyed hair grows back - 3-4 weeks, if the hair is healthy and full of energy.

Since regrown hair looks more neat than a fully colored hair at the same time interval, especially if you did not have bright contrast highlights, you can do it with an interval of 1.5 - 2 months.

Henna and Basma

Natural dyes henna and basma are really made only from natural raw materials. They can even be used by pregnant women without any fear for the health of the baby. But these colors are not suitable for everyone. Brunettes will not be able to become lighter with their help, but only deepen the natural dark shade.

Natural blonde can use basma only in combination with henna, otherwise she risks to turn green, especially if her hair has a warm shade.

Pure henna on blond will give a bright red, almost orange color, with which not everyone will feel comfortable. But the mixing of these colors in different proportions gives beautiful shades - from gold to dark chestnut.

Divorced only with water, henna and basma also dry hair and make it more dense. But if they are used in the composition of the masks with the addition of honey, burdock and castor oils, cinnamon and vitamins, then the weekly coloring gives an excellent result. After a month, the hair becomes thicker, lush, supple and easy to lay.

Modern alternative

Understanding what will happen if you often dye your hair, many women are looking for the safest solution. An excellent alternative are modern methods of uneven hair coloring: balayazh, ombre, shatush and others. They allow you to refresh the image, while maintaining natural roots. Professionally executed, these types of staining require correction about once every three months. Yes, and harm to hair is minimal, as the procedure is only selected strands or the lower part of the hair.

But this method works under the condition that you have the minimum amount of gray hair. Otherwise, even if the base tone is as close as possible to the natural tone, tinting the roots every 4-6 weeks is still unavoidable. However, the lower part of the head of hair will not suffer, which means that the tips will not break much.

Remember that most modern techniques are based on classical highlighting and imply a preliminary clarification of the selected strands. Therefore, even if you rarely tint, hair still need extra care. And it is better if it will be high-quality professional tools. Homemade masks based on natural oils quickly wash out the pigment, and will have to be painted more often.

Frequent hair lamination

Lamination is one of the cosmetic procedures, allowing for some time to make hair silky and smooth, keeping color and increasing volume up to 10-15%.

The procedure is not complicated and quick, with almost no contraindications, affordable:

• a special composition is applied to the hair,
• this composition envelops each hair individually,
• cuticles are sealed
• the surface of the hair becomes smooth.

If the hair is porous or badly damaged, lamination will be mild. It is advisable to pre-reconstruct the hair.

Gelatin will add shine to hair, but besides that there are many masks for shine, read about them here and choose the one that suits you.

Although there are no restrictions on the frequency of the procedures, since the Laminating Compound is completely harmless, contains healing biocomplexes.

It is desirable to carry out lamination on:

• weakened
• stained,
• damaged,
• dried,
• secant hair.

Healthy hair, with a dense structure of this procedure to anything.

How to restore hair after dyeing

Our hair needs constant care, treatment and nutrition. Especially with periodic exposure to coloring agents. Restore them using balms, special shampoos and keratin containing serums.

Be sure to eat the following foods:

• vegetables and legumes,
• chicken, as well as fish and dairy products,
