[posting for my husband who's to lazy to get an account

He swears by Aubrey Organics shampoo and conditioner. He is in the ocean more than he's on land, and used to have really dry, salty, sometimes smelly hair. He stared using their special line for swimmers and his hair improved by leaps and bounds. I would try their shampoo (if you shampoo), their conditioner, a good leave in, and experiment with some sort of deep treatment. I would just get on yourself about making sure you get all the salt out of your hair, and that you keep it as moisturized as possible.
I'm not sure if this would work for you but he also slicks his hair back with castor oil before he goes out. This seems to seal his hair and keep a lot of the saltwater from penetrating the cuticle.
Hope this helps!
