I swim every day in a pool with a lot of chlorine in the water plus I shampoo in hard water that has a lot of chlorine. Additionally, I color-treat my hair using developer to cover grey. All of these factors caused my scalp to get sores that itch and are sensitive. I used the Malibu C Scalp Therapy treatments twice within a two-week period and all of the sores and itching went away. I am now using the Malibu C Swimmers Wellness Shampoo and Miracle Repair treatment with once a week Scalp Therapy treatments. Now I can continue to dye my hair like before, swim every day and not worry about my scalp anymore. Thank you!
