(Concern) My forehead is gradually getting wider ㅜㅜ

My dad has a slightly (?) shortage of hair.

Grandpa is the same way~

My hairline was originally an M shape, but it is gradually widening.

I can see that the M-shaped area is gradually becoming empty...

Is there a way to solve this?

I wish there were some kind of procedure or treatment ㅠㅠ

I can't tie my hair up high, so I always tie it in a way that covers my hairline.
