Henna for hair: benefit or harm

Many women are familiar with such an oldmeans as henna for hair, the benefit of which is not only in careful coloring, but also in strengthening, giving a healthy shine and improving hair. However, each medal has a reverse side, and information began to appear that this tool can bring hair not only good, but also have a negative impact on them. What is the harm of henna? Let's understand.

Henna has been used since time immemorial asa coloring agent that gives the hair a reddish hue of varying degrees of saturation. What is the principle of coloring hair? Horny scales of each hair rise, and under them a particle of dye is built in, that's why hair gets a certain color. The same applies to henna hair. Its use in a beautiful tone that lasts for a very long time, practically not flushing with time. The finest particles thicken the hair, giving extra volume to the hair, especially at the roots. The natural origin of henna causes additional sympathy, especially in comparison with synthetic dyes possessing pungent chemical smells. In addition, this agent has pronounced antimicrobial and antifungal properties, which can help heal small irritations and inflammations on the scalp and relieve dandruff.

So what is wrong with henna for hair, benefitwhich seems so obvious? It turns out that it is the ability to penetrate the scales of the stratum corneum and causes unpleasant consequences of using this remedy. So, henna for hair harms, above all, the dry tips, which become even drier because of a violation of the hair structure, and then begin to sever strongly. That is, the action is the same, which is at the roots, which is at the tips, but the effect is fundamentally different.

However, do not assume that such an actionrenders exclusively henna. Any hair dye has the same principle of action. The only difference is that the substance that loosens the hair structure in the traditional paints available for sale is ammonia, and in the new generation paints - amines that are non-volatile and therefore do not emit a characteristic odor, but because of their nature they are washed out less and can stay on for a long time hair, causing them harm.

So, to what conclusions have we arrived? Is henna for hair good or bad? The benefit of using it exceeds the probable harm many times over. Of all the possible variants of coloring, it is the natural remedies that are most sparing, their minus only in the limited choice of colors and the fact that they can not paint the gray hair. If you are determined to change the color of your hair in the direction of the red, feel free to choose henna: the shade will be bright, radiant and will remain very long on the hair. Just remember that the hair colored with this product, the other paint is unlikely to fall: spots or areas of incomprehensible color may form. And it is useless to wait until the remnants of henna are washed out of hair - this will not happen. The only opportunity to change the color will be a cardinal haircut with the disposal of that part of the head of hear that was painted with this plant substance.

If you first decided to use henna,perform a skin sensitivity test, just like before using any other new remedy. Put a little substance on the inner part of the elbow fold, after the time you wash it off. Wait 24 hours, and if this place does not appear redness and other allergic manifestations - use health.

By the way, chemical perm is also "not friendly" withhenna. Most likely, chemistry does not have any effect on the hair, which is colored with this tool. And if there is already a wave, after coloring, the hair can straighten back, returning to its original state.
