i'm fifteen, and i start the swim season at my school in February. i was wondering if i could go to a salon/spa and get a wax without parental consent?

comments about how i'm to young to get a wax and all that is not helpful at all, so just don't put them.
i have tried shaving, but no matter what i do, i always get razor burn on my bikini line and it's hella embarrassing.
