Labo innovates once again with the White Hair treatment, which activates the production of melanin at the root of each hair resulting in the natural recoloring of the hair, without pigments.    The White Hair treatment, which stops the growth of white & gray hairs and restores the natural color is a dermo-cosmetic preparation for local use in vials, which promotes the production of melanin in the hair and helps to deal with the growth of white & gray hairs .    Aging of the skin and certain external factors cause the gradual disappearance of the melanin naturally present in the hair, discoloring it.
