I have the same thing! There are random peices at the nape of my neck, and behind my ears, that simply refuse to curl. My stylist cut them shorter than the rest of my hair... the only problem is that they appear to grow faster than hte rest of my hair so I have to keep cutting them shorter.

The only thing that seems to help is using gel and scrunching. And even then, by the second day they are back to being their limp little selves....
type 3a/b, baby fine to medium, normal to high porosity except the canopy which is high.
recently chopped off about 4" - HOW LIBERATING!!! Learning to love my hair again instead of hating it for being a knotty mess.
