Demi-permanent hair color is designed to enhance and intensify natural or previously color-treated hair. It doesnât permanently alter hair color, but it is long-lastingâup to 24 shampoosâand fades gradually, so you donât end up with a harsh regrowth line.
How long can you leave in demi permanent hair dye? I know for semi permanent hair dye you can leave it in for hours because there is no peroxide, ammonia, etc. But for demi permanent hair dye it does have a small amount of chemicals, so i was wondering how long you could leave it in with minimum hair damage. Thanks for answering. Follow.
