Advice on swimming with coloured hair

One of the effects of chlorine on bleached hair is to give it an unnatural shine like plastic barbie hair. It can also give the hair a slight green tinge although that's quite rare. The chlorine will also bond to your hair and complicate any chemical process you have in the future. My advice is to use a swimming hat and use a deep cleansing shampoo that is formulated for chlorine removal. Most manufacturers also make protective sprays and creams to protect against chlorine.
