Make lemonade, because life is sure giving you lemons if the iron and other metals that are tight with your hair are giving you a colorful mane. Squeeze fresh lemons over your hair and massage the juice throughout your tresses. Lemons contain citric acid; this natural ingredient strips the hard metals from your hair. Rinse your head after a few minutes and wash your hair as normal.
Grab a bottle of tomato juice and head to the shower. Similar to lemons, tomato juice is acidic and can remove iron buildup as well as the off-color of your hair. Shampoo and condition your hair after a good tomato juice soak to avoid smelling like you had a run-in with Pepe Le Pew.
Rummage through the pantry once more in your quest to remove iron buildup from your hair. Baking soda is a natural cleaner and can help you with your unintended dye job. In your hand or a plastic cup, combine your regular shampoo with baking soda until it forms a paste. Slather the paste onto your hair and wait for several minutes, maybe read a book in a bubble bath or simply attend to your other personal hygiene needs. Rinse your hair and wash again with plain shampoo.
Wash your hair with a swimmer's shampoo. Pools treated with chlorine also contain other hard metals that can build up in your hair just like iron. Shampoos designed for swimmers contain chemicals that remove the buildup without hurting your hair. Thank goodness for mass merchandisers and drugstores -- you'll find this type of product right on the shelves.
