Just for a little curl for the evening, I would prefer not to use either. If I had a choice I guess I would use the hot rollers not leaving them on too long.
Do you have any other rollers? You could moisturize your ends with a light cream and roll your hair and sit under the dryer for a bit.
Or you can do the same with satin foam rollers (if you have any) without the dryer and will have curls by the evening. I can get nice curls if I leave them in for a few hours.
Girl, GET SOME CARUSOS! Those will work wonders for you the next time you need to bump things up a bit.
