(Concern) How to prevent M-shaped hair loss?

Does hair loss strongly involve genetic factors?

My family has severe M-shaped hair loss.

Both my late uncle and father had severe M-shaped baldness.

All the older cousins in the big house also have M-shaped baldness.

I also have a severe M-shaped hair loss.

My relatives and I have severe M-shaped hair loss, so I am worried about my son.

I have an M-shaped hair loss that has already progressed severely, so there's nothing I can do about it, but...

My son wants to prevent the hereditary M-shaped hair loss in our family...

Are there any good prevention methods?
