My 11-year-old girl dives twice a week for years. Besides her hair is more orangeish (her natural hair color was brown), her skin is rougher than before. She does apply SPF 70+ sunscreen before going in the pool, but she refuses to put on any more sunscreen after she showers after the class.

My questions are:
(1) What's the best hair care product for her?
(2) Which skin care products are best for her - in the day time and at bed time?
(3) Is it safe for her to take Heliocare? If yes, what's the dosage? Is it OK to take it early in the morning even though her diving is 3:30 pm?
