My close male friend is really stressed out about his hair, so I'm looking for some recommendations for hair loss treatment.

He's still young, but I can see his hairline receding, and it makes me feel sorry for him when I look at him from the side, haha.

He seems really self-conscious about it too, as he keeps asking me where the famous places for hair loss treatment are, but I don't really know any, haha.

I would really like a place that isn't too commercialized and where the director personally examines him thoroughly.

Does anyone know of a clinic that is well-known among men through word of mouth and has skilled doctors?
