Question about a girl I know

[Cr779]

Hi, as a guy this is the first time I've posted in the women's hair loss section. To sum things up I noticed I was going through MPB around October, since then I've become VERY aware of people's hair. And like some kind of sick joke I also noticed that my friend, who I care a great deal about, is either loosing or has a receded hairline. She looks great with her hair down and I can't tell at all, but when she has it pulled back she's a norwood 2 with thin hair filling in the temples. I have no idea how hair loss for women works so I figured this would be a good place to ask.

Is her hair going to recede more? Or do women loose their hair in a different pattern? Or could it just stay where it is now?

Could it be because she always has her hair pulled back with a hair band pulling it back?

What could she do to help it?

The worst part is I can't say anything to her because we both kinda like each other but aren't dating yet, I think it would kill her if I said anything. It confuses me though because it's only noticeable when pulled back, but she wears her hair pulled back 9 times out of 10. I would have figured she would avoid that as women are usually more conscious of their looks. It makes me wonder if she doesn't notice her hairline, but somehow i can't see that being the case.
