I'm really paranoid about what I put in my hair, but France Luxes has some tiny tige boule barrettes that are very gentle on hair and work really well for what you want. They won't hold a whole lot of hair, but I find this actually works better, because they don't mess up curl pattern. They only come in colors, but they're pretty subtle.

they are pricey, but i'm eyeing the heart ones for my granddaughters. and, i could see myself buying one for me, nice to have one clip that would totally 'do the job.' i bookmarked it for possible future purchase.
