Don't waste your money.
So first off let me address the smell. Yes, it stinks. Is it going to make you want to vomit? No, its not THAT bad. All color removers have that sulfur smell. Now, let me address the effectiveness. I saw so many reviews praising this and how well it worked. I had high hopes for this as people were claiming it was getting the black and red out of their hair. I have really faded light pink/purple hair so I expected this to work really well on me, unfortunately it did NOTHING other than make my hair smell bad. Seriously, don't waste your money. If you can't bleach your hair due to it being overprocessed, just do a bleach bath instead of wasting your time on this. I followed the instructions completely, and even left it on for an extra 10 minutes when I realized 20 wasn't enough. Bummer.
