My head shape and facial features demand big, voluminous hair, and the only way I can achieve that look is with curls. I have a lot of hair, but it's super fine, so when it's straight, I look like a drowned rat--a hairless
drowned rat. It doesn't hold a curl or style when it's straight, so curly hair it is. Also, don't have to worry about the elements with my curls. Plus, I don't have to worry about every hair being in place. I love having "bed-head" 24/7.
I think straight hair that has been styled or has some curls and waves is very nice, but I loathe stick-straight, flat-ironed hair on just about everyone. Hate it. It's really not a flattering look on anyone--and I'm primarily talking about people who flat-iron the bejeezus out of their hair, thinking it looks nice.
Like jeepy, I'm not "me" without my curls. They make me unique because everyone else insists on wearing straight hair. Aaaand, curls knock about 15 years off my face--who wouldn't want that?
I also hate
flat side or middle parts. I see a lot of this with hair weaves and black women who wear relaxed, straight hair. I wore both hair weaves for years while I was growing out my hair and relaxers before that for many years, and my part was never flat. A part with some volume looks more natural, especially with a hair weave.
