Invest in silicone

Theres no magic product or ingredient, but if you want to add a little more protection you can use silicone -based products. Silicone basically coats the hair, which adds a little more protection once you do any kind of stress to the hair. Check a products list of ingredients and make sure silicone is high up on the list. Look for silicone or dimethicone, a silicone derivatives. Anti-frizz products usually have a silicone type of derivative. You can also try a leave-in conditioner, which also coats the hair.
