“Keratin reinforces the intercellular cement to join the scales of the hair,” explains Stéphane Weyl, head of training Fabio Salsa. When the hair runs out of keratin, it is more sensitive. Fortunately, there are care protocols, in salon, and keratin-fortified products to repair her damaged hair at home.

Keratin, a care to adopt in cure

Used as a cure, keratin reinforces the hair by depositing a kind of protective film on the fiber, to protect it from external aggressions. It also reconstitutes the structure of the hair, in depth. Keratin also helps to smooth and discipline frizzy hair , for example.

However, Stéphane Weyl warns against an automatic and excessive use of keratin: “As for vitamins or dietary supplements, keratin treatments are done by episode, so as not to overburden the hair.” To be sure of it, it is better to contact a hair professional to determine if there really is a need for a keratin treatment and if so, how often.

Be careful not to overload the hair in care with keratin

The longer your hair is, the closer the treatments will be. Also, Stéphane Weyl explains that it is possible, for very damaged hair, to resort, almost daily to specific shampoos.

The right combination to not over-sensitize your hair? Alternate shampoo with keratin and gentle shampoo and, always, spacing to the maximum the shampoos. Stéphane Weyl recalls that “too much is the enemy of good” and that the hair needs to breathe between two treatments.
