Best purple shampoo I have ever used! It actually tones AND repairs at the same time. My platinum blonde has never looked better — cool, bright, and healthy. A game changer for blondes.

Very pigmented so be careful with timing. I left it on for 5 minutes and got perfect results. Great that it also has the bond-building technology. My blonde hair feels stronger with each wash.
