Oh hi, new here. It’s really common in pregnancy for women to essentially stop losing their hair, which makes it appear thicker. But, come 3 or 4 months postpartum, all that extra hair kinda falls out at once. I’m 9 months pp and I have this ridiculous looking fringe from where it’s starting to grow back.
So yes, I’d say her hair will definitely thin out, and when it does she’ll most likely have a receding hairline until it starts growing out again (although who knows, as I don’t really remember her talking about hair loss with Fox, so in that case I’d say her hair isn’t actually thicker, it’s just the angle)
