I used this dye for my Peruvian hair and it did an exceptional job! I had previously purchased another brand and the hair did not change color at all but with this particular one, I noticed it began working even before I finished applying. Would definitely recommend this dye for hair. If your hair is intensely dark, it would be wise to use the bleach first to get the most of the colour. And on he plus side, the packaging includes a bleach pack as well.
