A 12-week scalp serum for hair fall and thinning-looking hair
Vichy Dercos Aminexil Clinical Regenerative Boost Serum is a lightweight daily scalp serum for men and women with hair fall and thinning-looking hair. It pairs 1.5% Aminexil, which works outside the hair bulb to improve root anchorage, with the R.E.G.E.N. complex of 3% niacinamide and ginger root extract, which supports the hair root from inside. Piroctone olamine soothes the scalp, and hair fall is reduced over time.
How it works
A light, fast-absorbing liquid applied to the scalp with a pipette. It is not greasy and needs no rinsing, so it fits into a morning routine.
Who it suits
- Men and women with hair fall
- Hair that looks thinner or less dense
- Sensitive scalps that feel tight or itchy
Worth knowing before you buy: the formula contains alcohol and fragrance. Results build over weeks, so plan on the full 12-week course.
Serum or ampoules?
The serum is the longer, 12-week programme for men and women. The Clinical 5 ampoules are a shorter six-week course, in a women's or men's version.
