Most people associate this unsightly colour change with swimming in a chlorinated pool, and quite rightly too, chlorinated pools often contain copper algaecides – a compound that helps prevent the growth of algae.
However, copper can also be found in home water supplies, especially if your pipes are made of copper, you can get a special water filter that helps to remove the copper.
There are a few things that can be done to avoid getting green hair. One is to wear a swimming cap in the pool, or use a waterproof protective hair product such as our Swimcap. If you already have green tinged hair, a lemon juice rinse can be quite effective.
