Another tip regarding hair...
I always buy some stuff from Boots that i spray onto my hair during the day, it protects against the sun, sea, and swimming pool, even has SPF 15 i think.
Another tip, although i didnt really bother in 2006, is to WEAR A HAT during the day.
The sun seriously drys out your hair, and you will end up with big chunks on skin coming off your scalp. It sounds horrible doesnt it?
As suggested by Sim, rub coconut oil into your hair during the day, and that spray from boots, or you could get it from somewhere else?
Especially when you get out of the swimming pool, then put your hat on.
