Using the corner of your comb and standing in front of a mirror find the middle of your left eye and then drag the comb straight up slowly until you reach your hairline and then continue back in a straight manner to achieve an even left part. A side part is great for longer face shapes because it creates the illusion of width.
Lift your hair up with your fingers and move the diffuser up to the ends, motioning the diffuser to the scalp in circular movements. Make sure the blow-dryer speed is on low and try not to completely dry the hair off. Leaving a little bit of moisture will allow the hair to dry naturally.
To finish, apply a minimal amount of hairspray from an arms length distance to the top, sides and back. Take care not to use too much or you will end up with a white, flaky residue which looks like dandruff.
