Hair coloringTo dye my hairI have white hair, unprocessed. My stylist added and accelerator, and used foils. Turned out great, still have color after 6 shampoos. Color does fade, but since it's 10 shampoos, that's to be expected. For the money...good deal.My son has very light colored hair we dyed his hair twice for 20 minutes and were happy with the results. Did mine just once for 20 minutes but my hair has been colored with highlights before so it took quickly.The color didn't take near my roots and it's more pink than peach on the rest of my hair. But, it's a nice pastel shade and I've gotten a lot of compliments on it. Not sure how many shampoos it will last through. I left it on for 30 minutes so we shall see.I have very light hair, applied formula for recommended length of time, plus 10 min. It barely tinted my hair, a very faint pink.Did not change hair color at all. It possibly could on light hair but not on medium brown which was very disappointingSmells great! Thats all the good i have to say. It left me maybe a tiny hint of possible purple in bright sunlight. Otherwise....nothing. my husband couldn't tell any difference. I left it on for 30 min and rinsed out with no soap. Light to medium brown is my natural color.
