Thanks for the replies!
It is really helpful just to know that someone else with experience has seen the same thing! Part of the difficulty is that I feel like nobody has any rock-solid answer for me, and I ultimately just want to know what to do to get my curly hair back. I know that at the end of the day it's "just hair" but it's a big self-esteem thing, and before it was something that I never worried about.
I am actually now switching to a non-hormonal form of contraception, and a different AED (anti epileptic drug) so I am really hoping that my hair will "bounce back." But honestly, I am a little worried that it has changed the shape of the follicle or something, or that now I am just stuck with this horrible 'in-between' hair forever. I really can't believe how difficult it has been to find any sort of information on this topic. I could find TONS on hair loss, but absolutely NOTHING on hair change. SO CONFUSING.
Anyway. Here's to better hair days!
