Coloured hair is often damaged because colour treatments can weaken the keratin chains in the hair. When this happens, colour pigments are unable to embed into the hair as well – resulting in the loss of colour intensity. For streaked, tinted and colour-treated hair, the REVITAL range uses a combination of magnolia and plant keratin, known as phytokeratin. These balance out the damage that has occurred in the hair and on its surface. The hair gains strength and a silky gloss whilst its colour becomes much more brilliant and long-lasting.
