Too much sun can be as bad for hair as it is for skin, especially hair that's been chemically treated. But never fear. Several hair-care products now contain sunscreen and use the sun's heat to condition while protecting.
One of the newest is Mastey Solfiltre Hair Sunscreen, available at Jadss International Hair Salon and Academy in Los Angeles and Danielle Coiffure in Beverly Hills. The non-aerosol spray, which has a sun protection factor of 4, can be applied to wet or dry hair hourly to keep hair moisturized.
