Dark & Lovely Reviving Colors #391 Radiant Black Semi-Perm (6 Pack)

I like this product because it can be used right after perming the hair. The longer you sit under the dryer the longer it lasts.

NOTHING. I LOVE THIS HAIR COLOR. IF YOU ARE ALLERGIC TO HAIR DYE, THIS IS THE PRODUCT FOR YOU. IT IS SAFE ENOUGH FOR ME TO COLOR EVERY WEEK--WITHOUT DAMAGING MY HAIR.
