Blow-drying your hair is easiest if you separate it into sections. Then, aim the dryer, bringing it a couple of inches away without letting the nozzle touch your hair. Here's where a lot of people make the mistake of holding the dryer more or less stationary for each section, which can cause damage by focusing heat on one part of the hair. Instead, make sure to start at the top of the head and move both the brush and dryer at the same time. It's a no-duh concept, but pay attention to how you normally dry your hair. You might be surprised by how long you keep the dryer on one section of hair, and how much better a blow-dry becomes with a little movement.
