Rhodiola rosea.
I have Lupus and just had a 2 month flare up. My hair falls out when this happens and doesn't seem to grow much at all.
I had shaved it very short because I was going grey and was cutting out my bleach.
My hair did not grow a cm, it was falling out in clumps and looked very fine.
I started these tablets to help with menopausal symptoms and within a week or 2 my hair seemed to grow loads.
I think they definitely helped, my hair still wasn't growing once the flare finished.
Posting in case they help anyone else. As an aside they have helped massively with menopausal anxiety too
