My transplant was 4 1/2 years ago. I was also losing hair. It’s not uncommon after a trauma from major surgery. I saw on this support group that some people took biotin to help with hair growth. I checked with my transplant team. The pharmacist sent me a message to take 1000 mgs a day. I did take it and my hair came back to normal. I stopped taking it after a year or less. My hair is still the same as presurgery.
I take tacrolimus and Cellcept.
