Thanks for the advice.
I'm going to try Bantu knots on Monday and see how that works before I buy flexirod thingys.
I get a bit of waves if I ball my hair up into one knot and sleep on that, but I want more temporary curls.
A while back I did a post on "Japanese straight perm"--just search and you'll find my info. My hair is stick straight, only if I reach and feel "inside" it seems a bit wavy at the root. I'm going to wait til Feb. to get another--maybe longer if I can--seems like this is going to last past the 3 months the salon said!
Sorry I would post more, but I'm having a bit of stomach ache!
