I had a hard time because of alopecia areata.

While working at the company, I experienced extreme stress, and one day I went to a hair salon to get a haircut. They showed me a mirror from behind, pointing out a coin-sized circular bald spot. I couldn't see the back, so I didn't realize it, but it turned out to be quite a large patch. I immediately went to the hospital, received an injection in that area, and after some time, my hair grew back.

I was worried that the alopecia wouldn't go away, but fortunately, my hair has completely grown back. Haha
