Head injury cause male pattern baldness to worsen?

[mania]

Male pattern baldness, which is mostly brought on by hormones and heredity, is unlikely to be directly exacerbated by a head injury, however it may result in temporary hair loss. However, shock-induced hair loss (telogen effluvium), in which hair follicles momentarily cease generating hair, can result from a head injury, albeit this is typically very temporary. Rarely, significant head trauma can result in scarring alopecia, which can cause the affected area to permanently lose its hair.
