So Redkens Extreme Blondage Toning Shampoo is a game changer!

Most purple shampoos have a high Ph, so that your cuticle opens enough to let the pigment in, however this clever little bag of tricks will repair your hair bonds and lock in the toner this way, and close you cuticle when finished. Works best with Redken Extreme Conditioner.
 
Treat yourself, you wont regret it!
