I LOVE this color! With dark unlightened hair (natural color is dark brown, nearly black) it doesn't show totally lightened to the red like on the side of the box, but I promise you after a wash or two it will. It smells wonderful and unless you have a super sensitive nose you can barely smell the chemicals.
The only con to this (and most hair color boxes) is if you have small hands/short fingers the gloves are FAR too big and there will be color all over your face, neck and ears.
The boxsays to let it sit for 25 minutes, because I have such thick hair, I tend to leave it in longer so it really sets.
