Please recommend a place that is good at hair loss treatment in the Seoul area.

My bangs are full, but the crown of my head is getting thinner and thinner.

I suddenly lost a lot of weight and my hair fell out, but I thought it would grow back.

It doesn't grow back as much as it fell out, and even these days, when I wash my hair, a lot of hair falls out.

If there is a place where I can receive hair loss treatment conveniently without using too many toxic drugs, please recommend it.

Anywhere in the Seoul area is fine.
