Back several years before i became bbc, i developed a stress induced nervous habit of plucking hairs from the crown of my head. It became bad enough that my mother noticed i was starting to have a bald spot there. Anyway eventually i found snd dealt with thevroot cause of my stress, and lo and behold the bald spot filled back in, and i csn legit say i am a by choice sly guy today. So stress can cause hair loss in a roundabout way, im living proof! Oh, and if anyone has any thoughts that some form of the same nervous habit is why i shaved, no, you're wrong. I did it becsuse i wanted to try something VERY different with my look, and found out i liked it, so kept with it
