Let me see if I understand what you are asking about, is it that your child makes you pull your hair out or that she is pulling her hair out (sorry for the aspie/neurovariant parent humor).
Like most things with neurovariants, clinician are great at giving them names but somehow understanding these things seams to elude them.
The most likely “reason” is that this is just another maladaptive manifestation, from some combination of anxiety, frustration, and sensory needs and differentials. Like all manefestation redirection to and alternate more benign variety is the best “short term solution”. Long term it is just continuing to work on accomidations and skills so she may “create” her own move more socially acceptable manefestations when needed.
I know this is probably not the focused answer you are looking for but I think it is the most likely
