I suddenly had alopecia areata. If you don't want to Google it, there were coin-sized areas of my head spontaneously losing hair, starting with my beard.

My GP said "this is not a health problem, if you want a fuller beard use rogain". I was embarrassed enough to go home and try to tough it out.

Within 6 months the whole left side of my head was completely bare, except for splotchy outlines here and there. My right side had hair but it was spreading fast. I looked like a hyena. It was not a great experience.

Went to a dermatologist, got steroid shots, and my hair grew back in a month.

You get quotes for housework, apply to multiple jobs, test drive cars, but when it comes to health, we trust the first asshole with availability? Never again.
