Absolut repair molecular serum when hair is damaged, its molecular structure, made up of peptides, is compromised. But most peptides are too large to be reinjected into the fiber, making the damage almost irreversible. Scientific discovery - absolut repair molecular. Repairs 2 years of damage in a single use*. How to use to use instead of your usual mask. Highly penetrating, it instantly transforms the internal part of the fiber. If necessary, you can complement the interior repair by coating the surface with absolut repair mask.

No exposure time is needed as the effectiveness is instantaneous. Rinse abundantly. [innovative technology] more than a superficial repair, it is an internal molecular repair. This exclusive rinse-off serum, concentrated with 2% bond repair + 5 amino acids, rebuilds the hair's molecular structure*** to restore its strength, elasticity and movement****. [deep penetration] inspired by ultra-potent skin care serums, it goes beyond classic repair masks and penetrates deep into the fiber to rebuild its molecular structure***. [instant transformation] instantly, hair is visibly transformed: shine and flexibility are considerably improved*****. [professional formula] its serum-like texture is immediately absorbed into the fiber and provides molecular repair*** without weighing it down.
