Husband's hair loss ㅠㅠ

My husband's hair loss is startingㅠㅠ

It seems like you're not paying attention right now...

I'm feeling anxious just watching.

My forehead is gradually getting wider...

If hair loss continues while watching TV, they say people get scalp tattoos like Yeom Kyung-hwan and Gu Jun-yeop.

Oh~~ what happened?

I'm using a hair loss shampoo...

I'm not sure how effective it is.

Should I get a hair transplant... I'm also worried about the cost.
