Blow Drying Like A Hairdresser
Start by removing most of the moisture from your hair.

With a wide-toothed comb, comb out small sections of your hair at a time. If you comb from the ends of your hair and work your way up this will prevent tangling. Hair is weaker when wet so be gentle.

Put the dryer on high air speed and high heat, and rotate the nozzle quickly all over your head, fluffing up your hair with your fingers. This is called roughdrying and it just removes heavy moisture. You hair should not be dry when you finished but damp.

Brush & Dry
Pin the top layers of your hair up out of the way with a banana clip. Starting with the lower sections of your hairbrush the hair from your scalp out to the ends, always following the movement of the brush with the dryer. This gives the hair volume. Do this to all sections of the hair letting down little by little of the damp hair until it's all dry and bouncy.

You can go to your hairdresser and ask for a blow-drying lesson. They will be happy to oblige.
