I'm kind of the opposite. I have to stay fairly clean shaven, as I have a weird reaction to my own beard hair where my follicles get infected if my facial hair gets too long.
When I worked at Eckard Drug Store, I was told I was one of six employees their customer service line had a script for to explain my medical conditions. Considering people would come in and quote my condition to me, I have a feeling it was true.
Also true was people were calling in to complain about me not shaving, the tremour, etc.
