StopGrey acts gently and gradually to restore hair to its natural colour between dark blond and light brown. Its natural-effect formulation does not change hair colour in a single application, but acts progressively, guaranteeing a natural, even result. Over a period of between 10 days and 3 weeks, this treatment replaces melanin with a pigment that restores the natural colour of your hair without saturating it or altering your look in a flashlike manner. Offering a simple and effective way of giving vitality and colour to hair, StopGrey is ideal for those who want a subtle and progressive change.
