Product Description Best for… The large barrel of the size 3 brush is best for blow-drying longer hair. This ceramic -barrelled brush retains its heat to allow for a faster blow-dry. To use… Blast hair until its 80% dry. Working with medium sections, place the brush into the root area and direct the heat from your dryer at the barrel. Keep the tension as you move the brush through your hair, directing heat at the barrel as you go. Style tip… To create soft waves, dry each section (as detailed above) and then wrap it around the brush. Direct heat from your dryer on to the barrel of the brush and then leave to cool for 30 seconds. Blast with the cool shot on your dryer before gently unwinding the section.
