Review (4/5): My Detailed experience using this product!
I waited to write a review till I used it(3 times). Yes it works. Yes it smells sulfurous, but it's not that horrible. I'm caucasian, not of ethnicity. Not course grey hair either. I have hard to dye hair (due to hormones) that always needs dyed twice to achieve desired color. Darkest brown. 1st use removed the color from the hair closest to my roots that was dyed the least. Heat Definitely NEEDS applied(which I tried the 2nd time). 20mins is NOT enough time, I went to 40mins (which I didn't try till the 3rd use. I was worried my hair would melt. It didn't & won't.) It turns the hair a red-ish auburn/orangey color depending on original shade. The 3rd time I used an ash blonde box dye after to neutralize the color remover instead of the 10 vol mixed with water. It gets darker after it's neutralized. It only lightened it to a medium brown on the darkest part of my hair. My hair still got dryed out. Not as bad as it would from stripping. So does works but it's not for everyone. I would recommend this product for a person who doesn't have any issues dying their hair. Or only needs a single dye job undone.
