Hair loss treatment for men in their 40s

I am in my 40s, and my husband is in his late 40s.

A few years ago, I was under a lot of stress due to work issues.

Crown area alopecia areata has started to appear.

At first, I went to the hair salon and the director told me.

Now that I can see everyone next to me, I'm worried too.

Please recommend a hospital in Jeonju that specializes in hair loss treatment.
