Hair dressers usually get commission off of anything they sell, so they will tell you anything. Try some serious deep conditioning. Leave a good quality conditioner on your hair with moisture and repair ability. Leave it on for about an hour 4-5 times a week. Leave it on a little longer while your in the shower to. Also put a leave in conditioner on your hair when ever your not treating it. Wearing a swimming cap in the pool may look silly but, it will save your hair from sooooo much damage.
