For me, short layers on top definitely give me more volume as well as how my face looks on me
. I'm trying to grow my hair out and have it angled (shorter in front, longer in back) and layered. I can't go with the long hair all over as it drags my face down. I usually wear bangs blown dry with a curl brush, so I keep my layers just on top shorter.
I don't plop as it just doesn't work for me. When my hair is almost dry, I take a big jaw clip, bend forward, gather my hair at the crown, put the clip in and kinda pull it just a bit. Gives me some volume when I take it down as well as helps with that Great Divide Crown Split I have going on at my crown
