@ladydidehart, After my liver and kidney transplant in 2009, I was taking cellcept, tacrolimus, and prednisone. I experienced hair loss and nail problems.
At my first post transplant visit (5 months) I asked the dermatologist who was part of my roitine post transplant care team. He said I could take biotin and see if it helped. My liver and kidney teams were okay with me taking it.
The girl who cuts my hair said it was a result of the medications both before, during, and after transplant. She suggested some gentle shampoo and conditioner that her cancer patients liked to use.
Ask your transplant team what they think about it. Will you be returning to the transplant dept for a 4-5 month check-up?
