Unfortunately, it did not work for me at all. I bought it for using on highlighted ombre hair, which I coloured from natural black. Unfortunately my hair does not react well to bleaching or any dyes, they get orange or yellow, even with cold-toned dyes.
The shampoo was recommended to me by a friend who was using it once every two weeks and claimed it was a miracle product. (It is true her hair colour does look good). I was hoping that it would help me, but I can hardly see the effect, even with everyday use and really massaging it into my hair.
In addition, it has a strong, sharp, chemical smell and dries the highlighted ends of my hair. My usual violet lotion works so much better. Maybe it is good for platinum blondes, but it can not cope with red-toned hair. I would like to try a version for a different hair colour one day, maybe "no orange" would be better for me, but I do not expect miracles and not sure I want to waste time trying.
