The reason I ask because when I really started to think about it, my hair is usually so close to the heat holes under the dryer. So if the hair is directly hitting my hair, wouldn't that be the same as if I had the blow dryer positioned to directly hit my hair. My hood dryer is 1875 watts and so is my blowdryer. Now mind you I know that blow dryers are damaging, that's why I never use them. I just trying to figure out if the hood dryer would be just as damaging. I know it shoulds crazy, but it seems as if blowdrying would actually be better because you are consistently moving the blowdryer around. On the other hand, when your under the dryer the heat is going in one direction down on your hair. Some one please help me to understand. I just cut off most of the dead ends of my hair and would like to start over. I definitely don't wanna destroy what I'm doing with heat. I would usually air dry, but I think that sleeping in rollers has helped to thin my hair. I have 4b very weak thin hair so every little thing I do to it snaps it like a twig.
