Using the corner of your comb, create a straight part and then place your comb at the hairline and drag it through your hair, crisscrossing from left to right as you go. When you reach your crown, lift the comb up and then split the hair to each side, pulling it down to reveal your zigzag part.
Take a small section of hair and place the ends at the base of your curling iron barrel and then wrap the hair up around the barrel until you reach your mid-lengths. Hold the hair for 5 to 10 seconds and then release the hair by unwinding the strands backwards.
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.
