Using moulding cream and your fingers grab the mid-lengths of your hair and then drag it out and upwards for a full and messy result.
To get your sides to sit out, apply a small amount of moulding cream to your fingertips and then working mainly on the ends, pinch them while dragging the hair in an out and upwards motion. The more moulding cream and the more pinching that you apply, the more textured and pasty the result.
Apply moulding cream to your fingertips, then grab a small section of hair and rub the moulding cream into the roots before twisting and pulling your hair upwards. For messier spikes, use a generous amount of moulding cream while twisting your hair in different directions.
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.
