The FACES OF FEY hair growth serum works with 5% capixyl and 4% anagain. The effectiveness of these substances has already been confirmed in studies, where they have been shown to improve the thickness and vitality of the hair. Anaagain works by interfering with the individual hair phases. The active ingredient extends the growth phase of the hair and ends its resting phase prematurely. As a result, more hair is in the active growth phase and the rest breaks are shorter. Anaagain thus has a positive effect on this ratio and effectively prevents hair loss. Capixyl acts like a kind of protective wall, as it protects the hair from fall-promoting substances and stabilizes the hair follicle. In addition, the hair growth serum contains biotin, caffeine, nettle extract and an innovative amino acid complex to ideally promote hair growth.
