My son is 10 years old.

Since last year, gray hair has been gradually appearing at the back of my head, and this year, it has increased quite a bitㅜㅜ

Are you experiencing a lot of stress?

Could there be a health issue?

When asked, he says he doesn't get stressed.

There are no issues with health in the basic tests...

It's hard to call it genetic.

My husband and I still don't have any gray hair.

I'm so upsetㅜㅜ

My son doesn't really care.

I'm so worried...ㅠㅠ

What should I do?
