Before shampooing, use a form of pre-conditioning treatment, which will reduce the amount of drying that takes place. It can be dyed and bleached; however, we recommend that you either come to the hair salon. Visit your local professional stylist to undergo this procedure rather than attempt it yourself in order to ensure that it is done correctly.
