Apply styling mousse to damp hair, using your palm as a measuring guide, and evenly distribute it along the hair shaft. Styling mousse will add hold and can help achieve better results.
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.
Apply a very small amount of smoothing shine to the palms of your hands and then run it through the mid-lengths and ends of your hair. Be careful not to add any to the roots or a large amount to any section of the hair as smoothing shine can be very heavy on the hair, weighing it down and making it appear oily.
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.
