Prevention methods for female crown hair loss

Women also have many concerns about hair loss.

I used to have a lot of hair, but as I get older, the density of hair on the crown area is decreasing.

Female hair loss may not be as visibly noticeable as male hair loss, but the sense of loss felt by women is just as profound as that experienced by men.

First, the hairstyle doesn't really stand out well.

So, I fill in the crown area with hair fiber to make it look darker.

Is there any way to prevent hair loss or to increase hair density again, besides these temporary measures?

Please tell me good ways to prevent or treat female scalp hair loss.
