works as described [SEP] wear the gloves haha i did not wear the gloves on my second application because i did not think it would say me that bad very and sure enough i had purple hands what side is it washes off your hands pretty fast it does work really well though however if your hair is already lighter in some sections than the rest you will have purple tint left over but on the parts that were golden that i actually needed to tone and did tone it down to a really pretty cool blonde i will use this probably once every couple of weeks to keep the brassiness at bay when i run out of this bottle i will definitely reinvest in another one
