What the heck happens to girls that makes them stop listening to their mothers??

My beautiful daughter (she'll be 12 next month) is growing her hair out. She had it in a very short spiky cut (as short as Angies new cut). It's been a year since her last short cut. (but she has had trims regularly). Right now, the back of her hair is the base of her neck (lower than her nape, but not anywhere near her shoulders). She is also growing out her bangs. Her hair is VERY thick, and the ends are getting wavy. Her goal is unclear--she just says she wants to grow it to her shoulders.

For some reason she is insisting on parting her hair in the middle and she's fighting the thickness and wave--trying to force it down. But that just makes it sit flat on her head then wing out at the ends. I finally got her to start to wearing headbands while she grows it out. Personally, I think it looks best when she pulls all of her hair away from her face, but she's been placing the headband over her head, so the grown out bangs are in front of the headband. It kind of defeats the purpose of the headband.

She would get really upset with me every time I booked her haircut. I know she needs to keep it shaped, but she just wants to let it grow out. I'm starting to think she's right. I think the layers the hairdresser is cutting in, is making the process much more painful. It's too short to pull back into a ponytail. I tried talking her into trying two ponytails, but she is very opposed to anything I may suggest.

So...does anyone have any ideas?? She can't wear hats in school. I'm not just looking for hair ideas, but mother guidance as well. I suggested she let me take some pictures of her hair parted on the side and in the middle so she could see photos and decide which she liked better. I suggested she use some hair product and go with the wave her hair has taken on with the onset of puberty. It's like whatever suggestions come from me are going to be denied just because it's coming from me.

And before we start a debate about just letting kids be kids.... She is very unhappy with her appearance right now. She's having some skin issues from a previous medication, and she's on a 30 day cycle of antibiotic along with a topical cream. She wears glasses, and she has 2 pair of very funky current frames that she likes. Even my husband is asking me to do something about her hair!! I keep telling him that it's part of growing up, and he should be happy she's going thru her awkward stage now, because it's much more difficult to go thru it at 13/14. Also, she is very tall (5'3", and from the neck down she looks more like a 15 year old than an almost 12 year old).

HELP!!!
