Women's hair loss concerns

I've heard a lot that hair loss is hereditary.

I wonder if I would have definitely done it if I had been born male.

My grandfather had hair loss, my father was fine, but my hair is thinning now.

My hair is thin, and I lose so much hair that it falls out when I touch it, when I brush it, and when I dry it.

The very old scar is crumbling.

Recently, after tying my hair, my forehead looks more exposed, and I feel like the hairline has moved higher.

The men's M-shaped hair loss is progressing, and my hair is now reaching about chest level.

Could it be that my hair is too long?

Would it be better to cut my hair a little shorter?

I'm worried that my shorter hair might make me look more plain.
