Yummy permanent is a versatile hair colour for salon professionals only. The range features amazing metallic colours and perfect pastel shades. The vegan formula provides long-lasting rich colour and is enriched with wheat bio extracts (nourishing and smoothing the damaged hair structure) and argan oil (making the hair softer, silkier and shinier). The vivid permanent colour provides perfect coverage of grey hair. The permanent hair dye requires a developer for application. It cannot be applied directly to the hair.
