Curly strands are prone to frizz when they dry naturally, so start styling while your hair is sopping wet. A mixture that’s great: Work in equal parts hydrating curling cream and an oil-based serum from roots to ends. If your strands still start to pouf, lightly rub on a glossing serum on dry hair to control frizzies. This trick will help block out humidity. And remember: Heat, UV rays and chemicals strip hair, making it porous, which aggravates the fluff. Comb in conditioner before diving into the pool to minimize chlorine damage.
