The Vichy Dercos Aminexil Clinical R.E.G.E.N. Booster is a scalp serum that works in two ways: the hair-renewing serum stimulates the growth of up to 14,000 hairs in 12 weeks. Additionally, the booster promotes the growth of existing hair. This is thanks to the advanced anti-hair loss technology with 1.5% Aminexil, which inhibits the hardening of collagen tissue. As a result, the hair follicle remains flexible and better supplied with blood, keeping the hair in the growth phase for a longer time. Niacinamide and ginger strengthen the hair follicles and enhance blood circulation in the scalp.
