perfect for redying
Worked ever better than permanent. Also stayed for almost two months. Beautiful colour, my hair feels so soft after using it. You can smell the dye in the beginning, but just use a nice smelling conditioner and you won't notice anything. I used it on already permanent dyed hair though. It didn't really dye my roots.
