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!
Love this product, it really works on toning my hair. The brassiness is gone, and a cool silver tone is easy to upkeep. A purple tinge will appear if overused, its as good as a salon product. Thankyou!
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!
