Females hair regulations: When you put your long hair in a sock bun, is it out of regs to put the excess hair in a braid around the bun?

I’ve been doing this for the past six years and my platoon got a new platoon Sfc and she tells me it’s out of regs. I have read the hair regulations front to back and the only thing that could make it an issue is the opinion of “fad” or “trend” but the purpose of putting it in the braid is so the loose hair doesn’t fall out and I don’t have to touch it till the end of the working day. The braid is also tight to my head... someone help me fight this argument because I just re enlisted for another six years and don’t have time for the bull shit that is being thrown my way.
