Permanent hair colouring treatment that gives an intense, natural and shiny result. It ensures long-lasting colour, optimal coverage of grey hair and is gentle on sensitive scalp and hair.

People who are looking for a product that is very well-tolerated by the skin and ensures intense, brilliant, long-lasting colour and excellent coverage of grey hair.

Bio-Colorist is enriched with sustainable and organic Argan Oil: an exclusive active ingredient that leaves hair soft, nourished and shiny. Because it has a high content of essential fatty acids and vitamin E, it favours cell oxygenation and protects the skin from external aggressions by neutralising free radicals.
