Preventing Swimmer's HairThe best way to prevent swimmer's hair is to keep the pool water from soaking into your hair. A swim cap will work for this. Limiting your hair's exposure also helps. You won't see much damage from the occasional dip in the pool, nor will you get damaged hair if you don't get your hair wet.
You can undo some damage and prevent further problems by showering after exiting the pool. It's best if you shampoo your hair, but even a quick rinse in fresh water will help remove the pool chemicals. Follow up with a conditioner to seal your hair's cuticle and replenish its protective coating.
Is Your Hair Damaged?Healthy hair is less susceptible to swimmer's hair than hair that already has damage. If you have colored, permed or heat-treated hair, your hair is at greater risk for dryness and color loss from swimming than it would be if you had untreated hair. If you swim a lot, try to minimize hair processing and keep up your cut so that chlorine won't get in through split ends.
A Word About Special ShampoosYou can purchase a special shampoo made just for swimmers. These products typically contain ingredients that will chelate copper and other metals so that they won't discolor your hair. The shampoo may leave a waxy coating on your hair, which is intended to prevent it from soaking up pool water. You may wish to alternate this shampoo with a clarifying shampoo, to prevent build-up which can weigh your hair down and dull its shine. Another option is to use a regular shampoo and follow-up with a leave-in conditioner. A conditioner that contains a UV-filter is a nice choice because it will confer protection from both the sun and the pool.
