Malibu hair treatments are used to counteract the effects of rust/hard water on the hair. They contain anti-oxidants that prevent the build-up of iron, calcium, magnesium and copper. There is a do-it-yourself treatment for your hair that you can make to accomplish the same thing.
Six Steps to Rust-Free Hair
Mix one to two packets of instant lemonade with enough water to form a paste. The amount of lemonade needed will vary by the length of your hair.

Put the shower cap on your head or wrap a towel around it. Leave on for 15 minutes.
Remove the towel or shower cap.
Shampoo hair as usual.
Apply this treatment once every one to two months as needed.
