it is just okay [SEP] i have used so many color remover products this one does a good job at lightening a color but has never fully removed the color from my hair if i simply want to lighten so as to reapply color this will do the trick if i am trying to go back to blonde this is not the brand i reach foras far as the smell it is about the same as all the other color removers i have used it is not the worst but it definitely has that sulfur scent that will stay in your hair for days unless you are bleaching after using this product as of now it is the price we pay to remove color deposits quicklyi cannot say i would recommend this product but that is just my opinion for my hair i keep a platinum blonde when i am not coloring for someone who has a darker shade this product may be all they need
