Do you not want the hair like that, Sera, or do you want it like that, but don't want to have to maintain it?
Because if you don't want it like that, then could you try not having it like that and see if you can live with the reactions (if any)?
I know that sounds easy to say, and I am not you, and I'm happy with a "feminine" style and reasonably happy with the associated maintenance (my hairdresser doesn't talk to me unnecessarily and lets me get on and read a book, it doesn't take that long, I can combine it with boring or fun errands). I did have 1/2" long hair aged 16 though but I don't really remember many negative comments. Though I may not have been paying attention, given my age, or perhaps it's more acceptable for teenagers to rebel.
It did rather sound like you didn't mind HAVING longer hair, just that you hated the maintenance, hence the tips for hair maintenance.
I hate the maintenance of little girls' long hair (I even hate the idea of the maintenance of little girls' long hair, as I've never had to do it, as DD's hair is still very short!) so we won't be growing her hair long. I actually don't particularly like the look of it but even if I liked it my dislike of the maintenance would probably overrule the look.
I am crossing my fingers that a weekly every other day brushing and a termly cut will be OK for her hair in either a bob or a shorter cut, the same as it is for DS.
