That roller style she used is mostly used for curtain bangs (the one she has). The ones you said are mostly used for blunt, fringe bangs. Some people use the one you said for their curtain bangs too, but it will look a little awkward because if you wanna achieve the curtain bang look, it would have to be straight and bent only at the end. If you roll it the way you said, it would be curled too high up your roots. Thats why, some people do it the other way instead. Hope this helps :) im sorry if I didn’t explain it quite clearly, english is not my first language so my grammar is a bit off. 😅
Maybe not since it might take some time to dry, if you’re gonna prep while doing so then maybe yes. You can try using a blow dryer to dry it while using your roller, that will solve the problem :)
Cute style, use a lifting product, don't pull the curlers out roll them out because your pulling the curl out, you can give your hair a shot if heat from a low setting blow dryer then wait for hair to cool down and then take curlers out. Thank you for sharing.
