My blonde hair becomes green when I use the public swimming pool. How can I prevent this?

Green hair makes it's appearance every summer. With more and more spas and Jacuzzi's becoming popular, it is starting to be a year round event. The green color is most noticeable in blonde hair although it can coat and damage any hair type.. Most people assume it is from the chlorine used to purify the water in pools and spas. Chlorine itself is colorless, but greenish compounds form in the pool/spa environment and are readily absorbed by porous hair strands. 

To remove it from the hair you will need to use products that are made for this purpose. Your hairdresser can recommend some chelating and clarifying shampoos. In unusually difficult cases, where the hair is extremely porous (such as bleached hair) your hairdresser may need to apply a color stripper chemical treatment. 

To prevent it's reoccurrence, you have to keep your hair out of the pool! If that isn't possible then you can minimize the hair's porosity by wetting the hair thoroughly before entering the pool. A good conditioner before swimming may help too.
