An innovative Collistar creation with a dual use: • after-shampoo mask to be applied as the second phase of the treatment • specific pre-shampoo pack for a more intense nourishing action recommended in the case of particularly dry and brittle hair. Creamy and easy to massage, it blends instantly with the hair, bringing its pure and concentrated active ingredients inside. It acts quickly and effectively, repairing and plumping the entire hair structure. From the first use the hair is visibly stronger and more voluminous, smoother and fuller to the touch, more disciplined and manageable.
