colour Soft is a hair dye created by the Salerm company. It is ideal for darkening, changing the reflection or completely dyeing white hair. This dye provides great coverage thanks to the action of its natural extracts of sage and rosemary, which protect the hair while adopting a new colour. It can dye up to 98% of hair completely white. The most relevant feature of this dye is that it does not contain ammonia, so it can be used before a permanent straightening without affecting the texture and health of the hair. It comes in a tube containing 100ml of product. It is recommended not to leave the dye on the hair for more than 20 minutes. This product needs to be combined with colour Soft developer emulsion.
