The lack of keratin makes the cuticle porous and fragile. As a result, the protective layer of the hair ceases to retain moisture, and the hair becomes dry, brittle and thin. If the amount of keratin in the stratum corneum decreases, the hair cuticle flakes loosely adhere to each other and bristle, so the strands look dull and lifeless, the tips splinter, the hair gets tangled, fuzzy and difficult to style.
Rational nutrition, shampoos, and hair masks with keratin, as well as keratin straightening will help to fill the keratin deficiency in the hair.
Thanks to keratin, hair follicles are supplied with nutrients and the structure of the hair is restored. Keratin hair straightening is the most effective way to fill your hair with keratin.
