I've got super hard water, a super chlorinated pool and super blonde hair. Malibu C Hard Water treatment, Blondes treatment and the Swimmers treatment are the only affordable solution to the extreme brassiness. They leave my hair looking freshly highlighted and less brittle. Less hair breaks off when brushing it now, as well. I wish I had known about Malibu C before cutting most of the damaged length off and learning about the products in beauty school.
