If the water you shower with has a high iron content, the mineral can build up in your hair, giving your locks a rust-colored hue. Some commercial products and salon treatments may remove the discoloration, but both are often expensive and vary in their effectiveness. Lemonade Kool-Aid, while not designed for use as a hair product, can do impressive job at removing rust stains for a fraction of the price.
Wet your hair thoroughly, then squirt a quarter-size dab of shampoo into the palm of your hand.
Open a packet or container of lemonade Kool-Aid and pour about 1 teaspoon of the powder into your hand with the shampoo.
Squirt another dab of shampoo into your hand, then mix the shampoo and Kool-Aid together with your fingers. If the mixture is too granular or thick, add a few drops of water to thin it out.
Apply the shampoo and Kool-Aid mixture to your hair. Coat each strand generously.
Allow the mixture to soak into your hair for five to 15 minutes.
Rinse the Kool-Aid and shampoo out of your hair. While rinsing, close your eyes to prevent the Kool-Aid from entering your eyes. Shampoo again without the Kool-Aid, then rinse to remove any remaining residue.
Condition your hair with your usual conditioning product.
