not a very good product [SEP] the only reason why i continue to use this product is because it is the only hot pink dye that is both affordable and convenient you could purchase it at walgreens other than that it is terrible i have naturally black hair and the instructions said that the bleach will turn my hair the accurate color in hours however it took hours to bleach a small strip of my hair to dye hot pink hours and it still did not bleach all the way the product itself is horrible instructions state that if you leave the dye in for minutes your hair will remain vibrant pink for months however this product washes out of my hair with every shampooing leaving my pink highlight a nasty neon orange color you literally have to reapply the dye and complete the entire dying process over again after every wash it is so time consuming and such a hassle though i know it is harming my hair i resorted to combing the dye through onto my highlight and then straightening it with a flat iron to drywill not be purchasing this product again and will definitely be looking for a new one i have finally come to my senses and realized that could be put to much better use
