ghd Natural Bristle brush size 2 .BEST FOR... The medium barrel of the size 2 brush makes it really versatile – producing a body-full or smooth blow-dry on short to mid-length hair. This ceramic -barrelled brush retains its heat to allow for a faster blow-dry. TO USE... Blast hair until it’s 80% dry. Working with small to 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 body in the crown, use your brush like a large roller. Dry your crown section (as above) and then wrap the whole section around your brush. Blast with hot air and then use your cool shot. Leave the brush in your hair and let it cool completely before removing.
