Are quads more prone to hairloss?

If you look at Christopher Reeves before he was injured, he had a great full head of hair,but by the time he died he was completely bald on the top of his scalp! I'm just wondering if people like myself or worse are more susceptible to male pattern baldness, because of the lack of movement and circulation, also a lack of fat absorption and utilization in the body, and maybe we don't absorb nutrients as well; let alone spread them across the body; to the hair in this case?
With all that in mind do you think foods that are known to help with circulation, can still benefit someone that is non ambulatory high quadriplegic with their circulation? Things like Cayanne pepper, ginger, gotu kola etc...
