Lift at the Root For Volume
No surprise here — volume starts at the root. So it's actually your brush technique that will give hair that extra lifted finish. For this step, start off by holding the hair 90 degrees above the crown of the head. Then, keep your chin up and pull a boar-bristle brush up and forward so that the underneath portion of the root is exposed, using the brush like you would a hair roller.
Continuously use the brush to roll your hair up and back, and release the hair in a C shape while drying. This technique will give you a sleek blowout with a subtle wave at the ends and extra volume at the root.
