To understand why you need to use shampoo for colored hair, you need to determine how such curls differ from natural ones. Bright saturated color is the most noticeable, but not their only feature. If we talk about good, then the hair that has undergone chemical coloring (and all cosmetic products for hair coloring is chemistry, apart from, perhaps, henna and basma), look more healthy, shiny and silky. Of course, if the staining procedure went according to all the rules using high-quality tube paint.
But there is another side to the coin. Hair coloring is a stress for our hair, which leads to a change in the structure of the hairline, because only in this way does the coloring pigment get into the hair. And shampoo for colored hair, in the first place, is designed to facilitate the post-stress fate of our hairstyle. In addition, of course, one of his main tasks is to preserve the resulting color, gloss and visual power for as long as possible. It is visual, because not a single
hair color will become healthier.
Based on the above features, shampoo for colored hair should have a slightly lower percentage of detergents in its composition than usual. Moreover, if among its components there are those that have a fixing effect on the dye, you can assume that you are very lucky. Hair is restored by strengthening and smoothing, the effect of which is provided by shampoo components that moisturize and nourish both the hair itself and the hair follicle.
In addition, good shampoos for colored hair should have in their composition a component that protects against the action of ultraviolet rays. In principle, any good shampoo should have this property, but for colored hair care products this is generally necessary, because ultraviolet “burns out” the pigment.
It is very difficult to purchase a care product that has all of the above properties. As a rule, the selected shampoo for colored hair copes with only one task. And it is unlikely that experts will help you choose the best one. You can follow their advice, but choosing the most worthy is a trial and error method that your hair will have to go through on its own.
The use of special detergents is far from everything that allows the colored hairline to have a healthy appearance. Any specialist, answering the question of how to care for dyed hair, will answer that you need to nourish and moisturize your hair not with shampoo, but with special masks and serums that affect the hair follicle, and not the hair itself. And this is correct, because the subcutaneous basis is the living part of the hair. Not bad coping with this task and improvised means. Home-made masks are often much more effective than expensive tube cosmetics. The fact that many "advanced" beauty salons offer their clients hair treatments based on the use of natural products that are available in almost every refrigerator also speaks about their benefits.
