How does hair coloring affect hair? About the dangers of chemical dyes on hair. Truth: Coloring is a chemical process

03.03.2020

Chemical hair dyes contain two main elements: a dye and a reagent. The first consists of synthetic substances and auxiliary components: ammonia, diaminbenzenes, phenylenediamines, resorcinol and phenols.

When we dye our hair, all these ingredients are mixed with each other. In this case, the oxidation process takes place. Ammonia molecules play a decisive role in it. With their participation, the hair swells, and the scales let the paint pass without problems and obstacles.

But the human body is designed in such a way that it is very sensitive to carcinogens contained in chemical paints, and the skin quickly absorbs them. There is even an opinion of scientists that breast cancer in women may be associated with this factor.

A bit of research

In the seventies of the last century, researchers made a sensational statistical discovery. It turned out that more than eighty out of a hundred people who had malignant tumors regularly dyed their hair for a long period of time. In addition, research by scientists has confirmed that the use of chemical paints increases the risk of diseases of the female reproductive system. Moreover, most of all this applies to brunettes and those who are painted in all shades of dark wood.

And manufacturers of permanent paints sometimes combine in them more than ten substances harmful to health at the same time. In a mixture, they act on the principle of a toxicological attack on the body.

That is why vegetable substitutes are an alternative to chemical paints. It does not contain phenyldiamine, 2,4-toluenediamine, 2-nitro-p-phenyldiamine, and 4-amine-nitrophenol. It is these substances that cause cancer in experimental animals. Some of them can cause DNA mutations. Using herbal dyes is a wonderful alternative to chemistry because they are safe for allergy sufferers, pregnant women, and perhaps even your future children.

Sometimes you want to change something in your life. "Something" can be marital status, work, place of residence, hair color. The last example seems to be the simplest way. An hour and a half - and from a burning brunette you turn into a blonde ... But is it so easy and simple?

The brunette turns ...

The modern arsenal of hairdresser's tools allows you to realize the most frivolous fantasies (from blonde to brunette and vice versa). However, according to stylists, such transformations are only possible for people who have a stylist, make-up artist and hairdresser at their disposal. For women who are far from stellar parties and model shows, stylists are not advised to change the color radically. Perfect transformation - no more than 4 tones. (They can be viewed and counted in the departments selling hair dyes.) And even in this case, you need to remember about the upcoming additional costs: you will need special shampoos, conditioners, balms, nourishing masks, more painstaking styling, constant (every 2-3 weeks) tinting. And although with the last point, you can learn how to cope at home, the resulting shade may be different from that of the master. Since, like any other specialty, coloring has a lot of professional secrets.

The secret of color

The most important. In order for the dye to penetrate into the hair, they are treated with a special acidic composition, which reveals the scales of the surface layer - the cuticle. Hair becomes more hygroscopic and porous.

The duration and technology of dyeing depends on the natural hair color. The lighter ones contain fewer naturally pigmented granules, so they are lighter, thinner and more hollow. Accordingly, the paint is absorbed more easily. Darker ones are more pigmented, so the places for the "loose proteins" to bond with the hair dye are a little trickier.

Color secrets must be solved from another point of view. If the desired color is lighter, first a substance is used that destroys the granules of its pigment, and then the desired paint. If the selected tone is darker, then only the dye. Naturally, the first option is more aggressive. When darkening, the dye fills in the hollow areas of the hair, while its own pigment remains.

After crystallization, the dye molecules are firmly fixed inside the hair, so it is rather difficult to extract them. For example, it will take an hour and a half to get rid of the paint that turned you into a burning brunette. And this process is very painstaking!

Completely bleached hair can be compared to a glass cone covered with a scaly layer. Therefore, if you want to return from a platinum blonde to a burning brunette, it will not be easy. Hair completely devoid of natural protein will completely refuse to hold the dye. Only special professional means can accustom him to order: first, you will need to "nourish" the hair with protein so that the dye has something to hold on to, and only then dye it.

The temperature mystery

The correct sequence for applying paint is as follows: temples, back of the head, forehead, parietal region. If you break it, then the shade will be different. The secret is that the number of blood vessels, and therefore the temperature of the skin, varies in different parts of the head. And since the speed of any chemical reaction, as you know from the course of chemistry, depends on the temperature, the color difference is quite understandable ... By the way, it is for this reason that the hair roots are painted over faster.

The secret of shades

Can we say with 100% certainty that if all the rules are followed, the color of the tester will correspond to the final result?

The stylist's positive answer to this question may indicate his insufficient incompetence. Despite the fact that the amount of the dye is weighed on an electronic balance, the amount of the fixative is measured in measuring cups, it is incredibly difficult to get a guaranteed result. Because determining hair type, degree of blonde, and color selection is akin to plotting a graph in a 3D coordinate system.

On the one hand, you need to take into account the existing hair tone, on the other hand, the necessary "strength" of the paint, and a whole section of physics. After all, colors "pass" into each other according to their own rules and laws, voiced by Newton himself! Since the green wavelength is between yellow and violet, experiments with repainting in one direction or the other can have unpredictable results. One should remember about such an accidental transformation even ... when going on vacation. Colorants and strong chemicals are sometimes added to pools to decontaminate the water. Therefore, the hair can accidentally acquire a blue, purple, greenish tint!

Special secrets

Certain taboos are associated with pregnancy. We hasten to please you: if the master observes all the rules, the paint may not come into contact with the scalp, and therefore toxic substances cannot enter the systemic circulation. One of the safest technologies is using foil. All the harm lies in chemical fumes, which are not very useful. Therefore, gynecologists are sometimes reinsured and advise against applying makeup during the first and last trimesters. The first is the time of laying all organs and systems of the child. The latter is due to the danger of developing allergies in the baby.

The mystery of gray hair

At first glance, it seems that after the loss of natural pigment, the hair should "keep" the color better. But the changes don't stop there. Gray hair is less elastic and seems to be knocked out of the styling. Its surface layer becomes denser, harder to "pass" the paint. In addition, due to the fact that there are fewer pores in the hair and even granules that have penetrated it are less fixed. Therefore, a slightly gray hair should be tidied up only by a specialist.

The secret of thick curls

Does the presence of natural curls affect the dyeing process? Yes! Straight hair in a section resembles a circle, wavy - an oval, and completely curly - stretched out like a ribbon. Therefore, they are all painted at different speeds.

But the staining process does not affect the density of the hair! Hair is formed in the middle layer of the skin and neither preparations for biowave, nor for dyeing do not get into it. They can begin to fall out only due to a chemical burn of the scalp. "Fallout" is often confused with breaking off. The latter is really the case, because no technology allows you to seal the cuticle cells perfectly.

The natural desire for beauty is inherent in every woman. And every woman in her own way strives to realize this impulse. Some - exhaust themselves with newfangled diets in order to throw off those extra pounds (in their opinion), others - change their hair colors, in search of their unique image and image. Tribute to fashion, fashion trends - all this pushes women to sacrifice for the sake of beauty.

Today the most affordable option for changing the image is exactly hair dye(there are, of course, and, but they are not cheap) . From thirty to forty-five minutes - and a stranger is looking at you from the mirror. About that, enough has already been written on our pages, but, how does the dye affect the hair, it will not be superfluous to remember and clarify ...

Is hair dye so useful and absolutely harmless, as its manufacturers indicate on the packaging?
What you need to know before taking the radical step of changing your image by dyeing your hair?

All modern paints can be roughly divided into the following categories:

- paints that contain ammonia,
- paints, which do not contain ammonia - "without ammonia paints",
- tinting agents,
- natural natural dyes.

Now let's look at all the "pros" and "cons" of each category of paints.

Paints that contain ammonia

Ammonia is a fairly toxic and persistent chemical with a characteristic pungent odor. It is the ammonia in such paints that determines the depth to which the coloring pigment penetrates into the hair structure, and it is he who is responsible for the intensity and brightness of the color. The result of dyeing hair with such a dye, which contains ammonia, will be a bright saturated color, which can remain so from six to twelve weeks (depending on the conscientiousness of the dye manufacturer). If you need to paint over gray hair, then no one can cope with this task better than paint with ammonia.

Now, as for the "cons"- your hair becomes lifeless, brittle and weak because ammonia not only dyes the hair, but also destructively affects both the outer hair column itself and the hair structure inside. The constant use of such dyes destroys both the structure of the hair itself and the natural pigment of your hair color. Having overexposed such a dye on your hair for a little more than the specified time, you can end up not only getting the “wrong” shade and color, but also losing part of your hair, lifeless hair will simply start falling out. In addition, any chemical that reacts with your skin, hair and body in general can cause an allergic reaction. Therefore, those who have a tendency to allergies, reduced protective functions of the body and have chronic diseases should, before purchasing paint containing ammonia, think carefully about the possible and not entirely pleasant consequences. In addition to poisonous and toxic ammonia, such paints also include parabens (special coloring substances), which have a bad feature - to accumulate in the body and provoke the development of oncological diseases.

"Ammonia-free" paints

In recent years, among those who take care of their health, they have become very popular. First of all, because they do not contain the hazardous substance ammonia. However, in order to achieve the desired hair color using this paint, it is necessary to take into account a number of nuances. The required shade is possible only on dark hair and only after their complete bleaching. This paint is suitable only for brown-haired women and owners of blond hair. The effect of such a paint on the hair structure is quite gentle, which is both a "plus" and a "minus" at the same time, since the final color of the dyeing is rather unstable and quickly washed off, which is noticeable after each shampooing.

Special tinting agents

Beauty experts consider using tinting products to be the safest and most harmless method of hair coloring. True, the palette of possible shades is limited to a natural natural color, perhaps variations on the theme of several tones are either lighter or darker from the main natural hair color. No harmful substances have yet been found in tinting agents, so they are considered to be harmless. The only "minus" in their direction is the low color fastness of staining.

Natural natural dyes

Natural dyes include plant-based dyes or dyes of natural origin. This is henna and basma, chamomile flowers, onion husks ... In ancient times, our great-grandmothers just with the help of these natural remedies changed their appearance and image. The indisputable "pluses" in favor of these natural dyes are, of course, the complete absence of a set of chemically aggressive substances. This allows you to preserve the natural beauty and care for your hair. If we talk about the "cons", then this is a weak coloring effect, possible uneven coloring, rapid washing off of hair color. If you do decide to try natural dyes, then do not forget the basic recommendations regarding their use. Take Basma, for example. This natural dye promotes hair growth, strengthens hair roots, eliminates the problem of dandruff, but you can only use basma in combination with henna, otherwise you will be provided with an original dark green color. But henna can be used separately from basma. Depending on your natural hair color and how long you will keep the henna on your hair, the final result of dyeing also depends. The palette of possible colors ranges from bright red and red to auburn hair.

If you suddenly decide to radically change not only the image but also the hair dye for a chemical one, then failure awaits you - chemicals hardly penetrate the natural layer of natural dyes, so you either have to use natural dyes to maintain color, or radically change not only hair color and dyeing method, but also the length of the hair itself.

Instructions

After the dyeing was done, if it was done according to all the rules, the hair begins to shine more, looks alive, becomes softer. This is especially true when using natural dyes such as henna or basma: they not only color the hair, but also take care of it, strengthen the hair itself and the scalp. Vitamins and microelements are necessarily included in the composition of modern hair dyes, and their effect on hair from the best side is obvious. Coloring gives hair a more aesthetic appearance, hiding uneven gray hair and signs of stress.

Nevertheless, even modern dyes are harmful to hair. Ammonia is contained in them in a much smaller amount than before, but without it, coloration will not occur. It affects the structure of the hair by destroying the hair column with frequent use. This is especially noticeable if the hair dye has been overexposed. First of all, the shade will be different from what was conceived. Hair after such a sad incident becomes dry and brittle, begins to fall out, the scalp often peels off. You have to spend a lot of time for restorative procedures, and only after a few months normal hair growth and structure is restored.

Only henna and basma can be considered completely harmless and 100% natural. But what to do if their palette is too poor and you want to change your hair color? In addition, the use of even only these dyes can also cause allergies, like any plant raw material. Do not forget that coloring with all other paints after applying henna and basma is difficult, and the result obtained can be distorted beyond recognition (for the most part these are shades of green of varying degrees of intensity). This is because the chemical components cannot penetrate the hair structure through the natural components that have clogged the entire structure in it, and only react with it, changing the color.

Considering all these factors, one has to conclude that the most harmful thing is frequent experiments of any kind on hair without the supervision of specialists. To assess the benefits and harms of dyeing each specific hair, an individual consultation with a specialist with extensive experience in this field is required. Even the most wonderful dye without ammonia applied to hair in can cause irreparable harm. And under the supervision of specialists, you can safely make platinum lightening with long-term perm for the safety of your hairstyle.

Not a single woman who systematically dyes her hair can say that her hair is completely healthy, shiny, there are no problems with it. With any type of dyeing, you have to constantly use hair strengthening products, and manufacturers of these products will never be left out of work while women dye their hair.

Why hair dye is harmful

Almost every woman has used hair dye in her life. And this is not surprising - after all, we all want to be unique and individual! But frequent use of dye significantly weakens the hair, and this applies even to the most expensive and high-quality dyes.

Is it harmful to dye your hair

The question as to whether hair dye is harmful to health remains open. Stylists and hairdressers are convinced that modern paints are absolutely safe, since they do not penetrate the body through the skin and have a safe composition, unlike their predecessors. Doctors and scientists, in turn, were divided in opinion: some believe that frequent staining can cause many dangerous diseases, up to cirrhosis of the liver and cancer, while others claim that staining once every two to three months with sparing agents will not do much harm.

Unhealthy beauty: the harm of hair dyes

Regular hair coloring can damage even the strongest hair. Scientists at the University of Southern California conducted a study that showed that women who use chemical hair dye at least once a month have a threefold increase in cancer risk.

Effect of dye on hair

The beauty confrontation between fans of natural beauty and adherents of its man-made version also touched upon the issue of hair coloring. Disputes about the dangers of paints do not fade for a moment: someone says that all paints are equally merciless to hair, and someone proves that less aggressive means exist in the world of cosmetic innovations. In this article we will try to figure out whether the dyeing process is so terrible, and whether we should be afraid for the condition of the hair.

The variety of hair dyes produced is simply amazing. All cosmetics of this type are subdivided into paints, which include ammonia, paints that do not contain ammonia, tinting agents and natural natural dyes. On closer inspection, all paints have positive and negative sides.

Why hair dye is dangerous to health

Experiments on laboratory animals have shown that these substances are capable of causing cancer and severe allergic reactions. These compounds are especially dangerous for pregnant women, because they have the ability to cause a change in DNA and provoke the development of developmental pathologies in the fetus.

Is hair coloring harmful: the opinion of a professional

Many girls are afraid to use ammonia dyes in hair dyeing. And to some extent they are right, because with inept use, as well as for those who are not familiar with the physiology of the hair, its density and structure, it will be difficult to carry out high-quality coloring. And here the fault will not be ammonia, but that which uses it. That is why it is better to entrust such work to a professional.

What are the health risks of hair dye

Most of the concerns are related to the use of permanent and semi-permanent paints, especially in dark shades (among which black is considered the most dangerous). The risk group includes those who constantly deal with chemical hair dyes (hairdressers), as well as women who have been using these products for a long time. The list of diseases resulting from the active and frequent use of paint includes:

Benefit or harm

Oxidation pigments (tone dyes) are special colorless or slightly colored aromatic amines, aminophenols or hydroxybenzenes, which, under the action of oxidizing agents, can form a cosmetic pigment, which is the colored compound inside the hair. Such compounds are insoluble and very strongly bind to keratin in the hair structure. The concentration of these oxidation pigments affects the color density of the dye and the time it takes to keep the dye on the hair. If you wash off the paint ahead of time, the color will be weaker, since the color molecules will not be able to show themselves "in all their glory."

How to dye your hair without harm? Overview of methods and recommendations

The dyes contain silk cream and inorganic compounds. The retention of the coloring pigment is carried out due to the different polarity of the ionic charges of the hair and silk cream. Safely using a dye, coloring and lightening up to 8 tones is performed.

How dangerous is it to dye your hair

It is still unknown what effect other chemicals in cosmetic products have during pregnancy, the amount of which in one bottle can reach several hundred. Studies on teratogenicity (harm to the embryo) have not been conducted in this regard. It is impossible to predict the effect of the interaction of the body with these substances.
