If you're really anal about not getting any chlorine in your hair, but not feeling the swim caps, use hair oil as a protectant before going into the water.
Created for the US Olympic swim team, Philip Kingsley's "Swimcap" cream (the perfect name) won't let any chlorine or salt water mess up your hair.
This shampoo actually removes chlorine and all that product buildup.
You can put this on before diving into the pool, or use it afterwards for softer hair.
After your day at the beach, undo the damage with this hair mask. It's like a crazy moisture surge.
