Start with clean, damp hair
Apply leave-in conditioner, mousse, or curl cream if desired
Attach the diffuser to your blow dryer
Set the dryer to low or medium heat
Set the airflow to low
Flip your head upside down or tilt it to the side
Place sections of hair into the diffuser cup
Move the diffuser slowly toward the scalp
Hold each section in the diffuser for a few seconds
Repeat around the head until hair is mostly dry
Use a cool shot at the end if desired
Avoid touching hair too much while drying
Stop when hair is about 80 to 90 percent dry
Let hair air-dry the rest of the way
