maybe try using a baby shampoo or head and shoulders? Not sure if it will work but they always leave my hair feeling stripped down.
I also found this on an answer website. (The Best product ive used is From Sallybeauty There are locations all over the country..
The product is called Ion Anti-Chlorine Swimmer's Shampoo.....They also have a conditioner (Ion Anti-Chlorine Swimmer's conditioner)....
Hope it all works out for you)
some even said to try ketchup or tomatoe juice. Hope you guys can figure it out in time
