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.
If you need to keep up your hair color, try to color at least 3 weeks after relaxing your hair. Use a penetrating deep conditioner on your hair and leave on for 15-20 minutes and sit under a dryer. Or try using a mask once a week.
