@tjgisewhite, Good morning to you, too. The words, "doing well", are wonderful to hear! At 4 months, will you be able to have a routine 4-mo post transplant check-up? When I reached my 4-mo point I was able to postpone it because of our son's wedding, so mine was a 5-mo check-up.
I also had thinning hair and even thinning/fragile finger and toe nails after transplant. I asked the dermatologist about it at my check-up and was told that I could take over-the-counter Biotin supplement. I suggest that you could ask about it and maybe it will help.
You will not get a lecture here on Connect, because we are all patients who 'Get it'. Each of us has experienced similar issues, and it is by sharing our experiences that we can support one another. Your question and your experiences are always welcome here because it helps all of us learn more about our own care.

Did you know that in addition to patient discussioins, there is a Pages section on Connect? In the Pages, you can read the information that is presented by the transplant staff. I am including some links -

(I am especially proud of this link because the staff used our group discussion, and the ideas that our members shared to compile this article)
