If your hair is dry and damaged, this is the washing treatment for you. Immediately after use, your hair will be silkier, glossier, more supple and tangle-free. The virtues of collagen are well known, and this treatment is good evidence of its importance. It is an active compound, closely resembling the one produced by our own bodies, which contributes to the process of the reproduction of living cells. Its ability to penetrate the epidermis has long been proven, and its subsequent effect on the scalp is to encourage the development and growth of the hair, reinforcing the protective sheath of the hair itself, re-establishing its natural balance. This is the base from which all our dry hair treatments are developed.
