Bump!
I sleep in curlers... that's the only way my hair takes a curl.
I remember my senior prom disaster... I went to the salon with my normal straight hair, and they could NOT get my hair to keep a curl with heat.. I went with half straight, half-curled hair. Disaster.
I wear my hair up most of the time, but it always looks like a bit of an updo with it curled and up.. love it that way.
