Wide-toothed comb Large round, boar-bristle brush Heat protectant product Hair oil or anti-frizz serum

If you don’t have a heat protectant product, apply leave-in conditioner or anti-frizz serum with mousse or gel to provide some hold. It’s better than drying your hair with no product at all. Avoid using too much product, since it could leave your hair looking limp and even greasy instead of shiny and sleek.

Rough drying protects your hair from getting too damaged by your hairbrush and dryer. If you go straight to using the brush, it will take twice as many passes to get each section of hair straight. It’s better to get most of the way there without a brush. Make sure to point the dryer so the air is blowing down the shaft of your hair from roots to tips, not up it. Aiming the blow dryer this way will help to keep the cuticle closed and create a smoother look.

If your hair lacks volume, you should brush your hair up. If you want it to lie flat, brush it toward the ground. Either way, keep the hair dryer angled down, so that the stream of air moves from the roots toward the tips. This helps the hair shaft lie flat and prevents frizzing. Move the dryer back and forth across your hair as well to prevent concentrating the heat into 1 area.
