Many women are familiar with such an ancient remedy as henna for hair, the use of which is not only in gentle coloring, but also in strengthening, giving a healthy shine and healthy hair. However, each medal has a flip side, and information began to appear that this tool can not only benefit hair, but also have a negative effect on it. What is the harm of henna? Let's get it right.
Henna has been used since time immemorial as a coloring agent that gives the hair a red tint of varying degrees of saturation. What is the principle of hair coloring based on ? The horny scales of each hair are lifted, and a dye particle is embedded under them, which is why the hair acquires a certain color. In the same way henna works for hair. Its use is in a beautiful tone, which lasts for a very long time, almost without washing off with time. The smallest particles thicken the hair, adding extra volume to the hairstyle, especially at the roots. The natural origin of henna causes additional sympathy, especially in comparison with synthetic dyes with acrid chemical odors. In addition, this agent has pronounced antimicrobial and antifungal properties that can help heal minor irritations and inflammations on the scalp and relieve dandruff.
So what is wrong with henna for hair, the benefits of which seem so obvious? It turns out that it is the ability to penetrate under the scales of the stratum corneum of the hair and causes the unpleasant consequences of using this tool. So, henna for hair causes harm, first of all, to dry ends, which become drier due to a violation of the hair structure, and subsequently begin to strongly split. That is, the action is the same, both at the roots and at the ends, but the effect is fundamentally different.
However, you should not assume that such an effect has exclusively henna. Any hair dye has the same principle of action. The only difference is that the substance that loosens the hair structure in traditional dyes on the market is ammonia, and in the new generation dyes are amines, which are non-volatile and therefore do not emit a characteristic odor, but because of their nature they are washed worse and can remain on for a long time. hair harming them.
So what conclusions have we come to? Is henna good for hair? The benefits of its use exceed the probable harm many times over. Of all the possible coloring options, it is natural remedies that are the most sparing, their minus is only in a limited choice of colors and in the fact that they are not able to paint gray hair. If you are determined to change the color of your hair towards the red, feel free to choose henna: the shade will be bright, radiant and will remain on your hair for a very long time. Just keep in mind that hair dyed with this product is unlikely to fall on another color: spots or patches of incomprehensible color may form. And it is useless to wait until the remnants of henna are washed out of the hair - this will not happen. The only way to change color will remain a cardinal haircut with getting rid of the part of the hair that has been dyed with this plant matter.
If you decide to use henna for the first time, do a skin sensitivity test, just as you would before using any other new product. Apply a little substance to the inside of the elbow, wash off after the appropriate time. Wait 24 hours, and if redness and other allergic manifestations do not appear at this place, use your health.
By the way, perm is also “not friendly” with henna. Most likely, chemistry will not have any effect on hair that is dyed with this product. And if the curl is already there, after dyeing, the hair can straighten back, returning to its original state.
