When we subject our hair to heat, we break it more than we know and basically fry it. For all heat protection I need, I reach for CHI 44 Iron Guard. (wow, con I sound cheesier?) This product smells like guys cologne(yum!) and protects you hair like armor. The trick to this is to let it dry before you heat it. Otherwise it will do just as much damage. I apply this mostly too my end but also a few sprays towards the top of my hair to ensure that my hair does not break off higher up on my head. 5 stars from moi.
