It works for me. I colored my hair from dark brown to blond and it turned out brassy and orange in the roots. It’s not fully gone but it is way better than before. I leave the shampoo In for 5-10 minutes. It really dries the hair so you need a good hydrating conditioner afterwards. Can recommend!
This is the first purple shampoo that I've used that has actually made a noticeable difference to my hair colour! Even better that it's paraben and sulphate free! I've had so many compliments, ill definitely buy again!
This is the best purple shampoo i have used. Its really strong, so definitely use the gloves provided or your hands will be purple for days! Really does bring out the silver in your hair. The only negative is that it is quite drying so you need a good condition, but since my hair is oily, i find it a plus!
