I wear my hair in a pony puff (which in my mind is the equivalent of a pony tail for straight hair); a bun, a chignon, a sloppy french roll, or just down in a shake and go occasionally. Any sort of two-strand twist styles (especially in a bun or ponytail) are great too.
When my hair was too short for those styles, I just wore a shake and go daily with a scarf headband or click-clacks. It really is no biggie--all of my (white) coworkers wear their hair in the same style daily, so it's not like anyone really cared--
only my black female coworkers will show up with a phony pony one day, a wig the next, and a regular straight do the next week.
