Rated 5 out of 5 by T Atencio from Love it I really like how effective this shampoo is at keeping my hair the perfect blonde. I do mix a little of no.4 shampoo in since it does leave a little color on my scalp.

Rated 4 out of 5 by Ĺori from Love the purple I have Grey curly 2C hair and I decided to try the shampoo. I LOVE the purple base, but it does stain your hands. I didn't love that it felt like I was using a clarifying shampoo and for my hair that's not good. I will not be purchasing again

Rated 5 out of 5 by Angelique from best purple shampoo 💜 Love this shampoo for blonde, silver, and white hair! I rarely have to tone since this shampoo launched. I seal with clear and that is it! Saves money and time. This shampoo does not leave a rosy hue, is not drying, and gets pretty sudsy too. For some clients, I mix half N4P and half N4.

Rated 1 out of 5 by Brooke from Unsellable I bought a few of these they came spilled in my whole box. They are no longer full and everything is purple. They are unsellable as well as everything else.

Rated 5 out of 5 by Caroline1989 from Great for aging-dry hair My mother raves about this shampoo. She says when her hair turned grey it became dull and course not shiny and soft as it once was. She started using this and says her hair has never felt better, and I can attest to it looking absolutely amazing!

Rated 5 out of 5 by Cortney from Beautiful The purple is very intense I recommend using it sparingly just as you would their regular shampoo.
