Hi! I, too, am an avid adult swimmer. I tried everything as well to keep my hair dry, especially since we are swimming in chlorine water. Nothing works, However, I was also told by the lifeguards to put conditioner on my hair before I swim, and/or vaseline from the middle part down, all around the hair. What that does it lock in your hair, so to speak, from chlorine messing it up. Let’s face it, chlorine is a chemical, and it goes right onto our locks, and damages our hair. Make sure you use a good shampoo made for swimmers, and a good conditioner for the same purpose. Never, ever, get a perm, and then eventually go swimming, bathing cap or no bathing cap. I made the mistake of doing that, and it took almost two years for my hair to feel , and get back to normal again. With that said, swimming is an excellent sport, it moves every muscle in your body, and gives one a long, lean look, and I’m not that tall, but I feel longer and leaner from swimming. Good-Luck!!!!!
