For blow-drying longer-hair
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.
Blast hair until it’s 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.
