A leave-in scalp serum that boosts fuller-looking hair
Klorane Strengthening Serum with Quinine and Organic Edelweiss is a leave-in scalp serum for men and women with thinner-looking hair. Quinine extract, Klorane's signature active for hair, works with organic edelweiss extract and caffeine to energise the scalp. A complex of B vitamins (biotin, niacinamide, panthenol and pyridoxine) with manganese PCA helps strengthen the hair, so hair looks thicker and denser over the course of use. It does not need rinsing and does not weigh hair down.
How it works
A light, fresh lotion applied straight to the scalp with the nozzle. Menthol gives a cooling feel on application, it dries quickly and leaves no greasy residue, so hair can be styled as usual.
Who it suits
- Men and women whose hair looks thinner from time to time or with the seasons
- Hair that looks thinner or less dense
- Anyone following a Klorane Quinine routine
- Fine hair that should not be weighed down
Worth knowing before you buy: it contains denatured alcohol, menthol and fragrance, which can sting a sensitive or irritated scalp. It gives fuller-looking hair.
