Salt is also damaging to the hair. You think that regular shampoo is going to save your hair from that salt water? Think again, salt can cut through your hair and leave it dry/brittle. It's so important to use a shampoo that is made for swimmers. Your hair does not have to suffer, you can swim and have healthy hair. Proper conditioning is also imperative. A moisturizing conditioner is what you want to follow the shampoo three up with. I have a few different moisturizing conditioner I like to use.
1) Design Essentials (instant moisturizer)
2) Joico Moisture recovery
3) Paul Mitchell (tea tree Lavender)
4) Matrix (hydrating or smoothing)
5) Ginger Lily Farms (moisturizing awapuhi)
