Went on very easily, but did not come out the way it should have. The black turns a very vibrant purple on a medium brown hair colour. Do not expect the exact colour that appears on the box. Not too sure how the purple came out of the black colour but it did. Would not recomend to anyone with natrual or dyed brown hair wanting to attempt black.

The colours I used just didn't change my hair all that much. I went from dirty blond to... a slightly coppery dirty blond. No one even noticed the change.
