By its very nature dry hair suffers from a lack of sebum in the scalp. Deprived of its natural protection, the cuticle dries up and is damaged. The intercellular cement becomes permeable. The hair loses its water and lipid content. Dehydrated from the inside, the hair looks rough, dull and undisciplined. The Hydra Active range is designed to nourish and bring shine and softness to dry hair. Rich in essential fatty acids and micro-nutrients, it restores the lipid barrier to combat dehydration and restore softness, suppleness, tameness and shine to the hair, without weighing it down.
