First, on wet hair, spray leave-in conditioner or detangler so that you’re not ripping at your hair as you brush it out. Not on wet hair! Second, blow your bangs section out first. The sooner you blow this out, the more control you’ll have over parting. After partially drying, apply a frizz tamer, argan oil or protective serum. Just a little from the middle of your hair to the ends. At the fifth picture you can see that the girl is pulling the sections around as she drys. Stretching them will smooth them and make sure that the hair is laying evenly on the brush. Continue like that until you reach the top! After the hair has cooled, take the nozzle off, flip your head over and "stir it up". It's very useful, try it, you can't make a mistake!
