The decision to go blonde requires some serious commitment. It takes financial dedication and a whole lot of TLC. But one of the number one things you need after taking the plunge is a quality purple shampoo. Purple shampoos are cleansers with purple pigments to keep the hair's undertones cool. Though many still don't understand what that has to do with keeping hair blonde, the science behind these shampoos is fool-proof.
So for anyone who is blonde, or thinking about going light, you should consider adding one of these 17 shampoos to your collection.
