A strengthening protein hair mask and treatment extender for damaged hair.          
As its name suggests, Redken Extreme Mega Mask does not play around when it comes to strengthening damaged hair—and that’s a very good thing. As part of Redken’s Extreme hair care line, this hair mask features the new RCT Protein Complex, which nourishes from root to core to tip, to provide deep, intense conditioning and to strengthen and repair damaged hair and reduce breakage. The effect is so dramatic, it lasts up to three washes. What’s cool: the mask actually comes in a bottle that has a dual chamber housing two different formulas. It also makes hair 15X stronger when used with Redken Extreme Shampoo and Conditioner.            
Use every 3rd wash or whenever intense conditioning is needed. After shampooing, apply to towel-dried hair. Leave on 3-5 minutes. Rinse thoroughly.
