I have been using the Redken Extreme shampoo and conditioner for a year now and let me tell you.... you NEED it!!! It's amazing!! Here is my before and after of around a years difference, from over processed, blonde, damaged, snapped all over hair to healthy, shiny, all one length hair ๐! I honestly can't rave about it enough. I also use a weekly hair mask and the Reken Extreme leave in conditioner.... don't walk..... RUN!!
