Review (2/5): It's just okay
I've 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'm trying to go back to blonde this is not the brand I reach for.
As far as the smell it's about the same as all the other color removers I've used. It's 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's the price we pay to remove color deposits quickly.
I can't say I'd recommend this product but that's just my opinion for my hair. I keep a platinum blonde when I'm not coloring. For someone who has a darker shade this product may be all they need.
