3 Before you take a dip…
Get your hair wet with clean water before entering the pool or ocean. Your hair won't absorb as much chemicals or saltwater. Use clean water and/or a leave-in conditioner. Also, try to rinse your hair afterwards, too. If there isn't a shower nearby, keep a spray bottle filled with fresh water.
4 Wash less often
Summer is very drying on our tresses. Washing less allows our hair to retain as much natural oil as possible. Exactly how often you shampoo is a personal decision based on your lifestyle and how oily your scalp gets. Use dry shampoo or a co-wash in place of regular shampoo to go a bit longer between washes.
