Is hair growth in pregnant dependant on boy/girl hormones?

[Wuxiapian]

With DC1, a boy, my hair was full, thick and luscious - no hair loss.
With DC2, a boy, pretty much the same.
I'm 20 weeks with DC3, a girl, and hair is shedding at an alarming rate.

Has anyone else experienced this?
Could it be due to different hormones in the body?

TIA.

I've had a DS and I lost loads of hair.

I've had two girls and yes I'm normally very hairy but the hair on my legs etc practically stoped growing, I'd usually have to shave every 2 days and I hardly had to do it at all, it's the only old wives take I've actually found true based on people I know that boys seem to make you have the same/ more and girls less so maybe this will be dd1! Will you find out?

Oh you did sorry, but yes I found it to be true
