3 Common Haircare Mistakes—and How to Fix Them

You Use a Clarifying Shampoo—Every Day

Though clarifying shampoos clean hair and scalp of residue left by chlorine, saltwater, and styling products, they also strip hair of moisture—which leads to frizz, says Gibson.

Use deep-cleansing shampoos only once a month, and wash with a gentle moisturizing formula (like Aveeno Nourish+Shine Shampoo) the rest of the time.

To prevent residue buildup, apply half a tablespoon of a light conditioner from roots to ends before jumping in the pool or ocean; the conditioner seals the hair's cuticle, creating a protective barrier.
