Lynniecat hello,
I would imagine that hair thinning can be just one more thing that you have to give up due to Lupus. And such nice hair too. but others have given you good advice it seems, in response to your hair. and a dermotolgist seems to be a good way to fight back against the loss of so many things because of Lupus.
Hang in there. Everyday can be that day that finds you with a change that finds your thinning hair becoming thicker again. When I used to take prednisone, I didn't even know that prednisone even caused thinning hair. Much more is known today than it was in 1996. Not much to give you I guess, but a little bit hope.
