To protect your hair from all the chemicals in pool water and prevent swimmers hair try a do it yourself spray on hair protector.
If you get into the pool with dry hair your hair soaks up the water and chemical treatments in the pool. Preventing that is simple. Don't get in with dry hair. Wet your hair with a spray made of 10 parts water to 1 part conditioner. Having your hair already wet means the water doesn't absorb right in to your hair and the conditioner is an extra shield of protection.
This is great to stash for the kids near the pool or in the beach bag to go.
