A little distance between the hair dryer and your hair is essential for your hair health. Generally speaking, you should hold the unit at least eight inches away. Sure, it looks like a long distance, so you feel like getting it closer for faster results – quite a mistake. Also, those with fine hair must use the lower settings for good results. If they push for more, chances are they will end up with a tangling hair. Of course, it does depend on what kind of dryer you purchase as well. Check some hair dryer reviews and make an informed decision.
