Choosing a new hair colour is an ideal way to renew your appearance, though doing it at home makes you susceptible to hair colour mistakes. Though a mistake can be alarming, it is easily fixed so you don't have to walk around with green hair. If you are blond, constant exposure to chlorine in swimming pools may cause a green tinge to appear in the hair, but is fixed using natural ingredients or products found in retail stores.
Purchase an at-home colour kit that has red tones to neutralise the green tinge in the hair caused by a previous hair colour mistake. Stick to a shade that is closest to your natural shade to avoid the hair looking too dark or light. If you have blond hair, choose a shade like strawberry or golden blond; if you have brown hair, select a shade such as auburn or red brown.
Apply colour to the entire head, working it into the hair from the roots to tips. Allow to sit on the hair according to package instructions, usually 25 to 30 minutes.
Rinse your hair with warm water until the water runs clear, and apply the deep conditioner provided in the colour kit to the entire head. Leave on for five minutes and rinse completely.
Apply pure tomato juice or ketchup to dry hair and massage into the scalp and hair. The redness in the juice or ketchup will neutralise the green tinge caused by chlorine and sun exposure. Allow the juice to sit in the hair for 20 to 30 minutes, and rinse with warm water in the shower.
Repeat the treatment as necessary to remove the green from your hair.
Wash your hair each time you swim with chlorine-removing hair shampoo. The shampoo, found in retail or drugstores, contains sodium laureth sulphate and tocopheryl acetate to help remove chlorine from hair. The shampoo is safe for all hair types and ages. The shampoo also adds conditioning to hair, which is beneficial since chlorine and sun exposure also dry hair out.
