Bleached hair can turn green in a swimming pool due to the reaction between the chlorine and the hair. Chlorine can react with the copper present in the water, which can cause a green tint to appear on bleached hair. To prevent this, it is recommended to wet the hair with non-chlorinated water before entering the pool and to use a swim cap to protect the hair from direct contact with the chlorinated water. Additionally, using a clarifying shampoo after swimming can help remove any chlorine buildup and prevent the hair from turning green. **

It is always best to check with the specific pool facility for their rules and regulations regarding footwear. **
