I can't do it. My hairs so long I need to pull it up with one comb and hold it while I spray/blow dry. I've always had to do it that way so I can't really imagine any other way. Sorry I cant help you.
Okay this is a pretty tricky one. Okay one comb you use to pull your hair up. Hair spray the section, then drop the hairspray, grab the other comb and pull it up to the first one, and hold them both with the one hand. Then hair dry. At least, thats what I did the one time I tried it. Tell me if it works for you.
Okay, I use this technique everytime. You go at your hawk from both sides with the combs, pull up, and when you get a nice pull at the top you can just hold, spray, hairdryer, switch hands, repeat. It's honestly the easiest and best way I've put it up to date.
