Set includes Redken Extreme Shampoo 500ml, Redken Extreme Conditioner 500ml and Redken Extreme Strength Builder Plus Mask 250ml. The shampoo gently cleanses while strengthening and fortifying weakened, damaged hair and helps protect natural shine. The conditioner delivers targeted root-to-tip nourishment to repair, smooth and leave hair supple and glossy. The Strength Builder Plus Mask provides deep conditioning to strengthen hair from the inside out, improve manageability and reduce breakage by up to 28%. Directions: apply shampoo, lather and rinse; follow with conditioner and rinse. After shampooing, apply the mask to towel-dried hair, leave on for 5 minutes (or longer for deeper conditioning) and rinse thoroughly.
