Review (4/5): It worked
My natural hair is curly and red, I have been dying it a dark violet forn couple years and decided to go back to natural with less root showing. I'm trying to let my hair grow out so I used the color reverse ( it super stinks) but it knocked the color down to a brassy shade much closer to my natural hair color in just 1 try. It dried it out abit so I deep conditioned after which also helped with the smell. Did not burn or irritate my scalp. All in all I'm happy. I gave it only 4 stars cuz the smell is so bad!!!
