4.3 Straightening Your Hair
Take a small section of hair. Starting from the roots, slowly glide the brush down to the ends of your hair. Repeat this process for each section until your desired straightness is achieved. The anti-scald rounded comb teeth are designed to protect your scalp from direct heat.
