It sounds weird, but it is a fact that if you dampen your hair with water before entering the swimming pool, your hair might not absorb much of the chlorine. If your hair would be saturated with water, it gives less room for chemicals to get absorbed as compared to dry and porous hair. You can also apply a leave-in conditioner on your hair that protects your hair from chlorine damage. African Pride Olive Miracle Anti-Breakage Leave-In Conditioner is considered the best to apply on your hair and scalp before entering the pool.
