Does Air Drying your hair, damage it?

No. In my profesional opinión. Your textured hair is alway searching for moisture. By Defusing your hair you are locking that moisture in , by creating a cast to keep the moisture in the hair. When air drying you are also creating that cast to lock in the moisture to maintain the maximum moisture your hair is searching for. Its good for you to know that your hair is constantly talking to you. If your hair is on point, but you have one area or one piece that is either droopy or straight. It is telling you that you need to pay more attention to it, by scrunching and squishing water and conditioner into it, or it wants more product to lock in that moisture.

So no, again in my professional opinion air drying your hair does not damage the hair.
