There's no such thing. But what you can do is every weekend, trim just the bottom of your hair, you don't have to cut it. Just to get rid of split ends or dead ends. Then when you shampoo it's gonna help it grow faster. It's a true fact.
any shampoo labeled ';for colored hair'; will do it b/c it has extra protein in it which will help ur hair grow
