I usually take a bottle of condish mixed with water, and spray my hair with that after i've gotten out of the pool. It's also good to wet your hair with regular water right before you get in, that way your hair might not soak up as much chlorine. I smoothe some shea butter, like CB's shea it ain't so before I get in. Just today I went swimming, but I just condition washed with Suave Naturals Mango & Peach, then used Too Shea. So I don't think you need to shampoo every time afterwards.
