Hair texture changes on HRT

I suspect that the progesterone I'm taking is affecting the texture of my hair. It's suddenly got very dry, frizzy, and lost it's volume. Has anyone found this is a temporary thing, or is it simply what progesterone HRT does while on it and you'd have to go off to see an improvement?

Edit: The change happened suddenly when I started taking HRT. Before my hair was ok. So this isn't about when hair gradually shifts in peri, but about HRT. Thanks!
