Review (4/5): Works for me!
I like that this brand/product only stays a few days, because the trade-off is that it seems to have no damaging effects at all on the area I used it on. Also, sometimes it's good not to have to strip out or bleach out a color. I spray it on the ends or area I want it to color, and leave it overnight, and when I shower in the morning, it's in there good. I should mention that my hair is straight and very pale, so take this into account concerning my opinion of the results.
