@shepn7 my liver transplant was almost 10 months ago. I take tacrolimus and Cellcept. I noticed my hair thinning and feeling straw- like about 2 months ago. It didn’t come out in clumps but I had to call the plumber and get special drain nets. There were long strands of my shoulder length brown hair on my pillow each morning. My transplant team approved use of biotin 1000 mcg each day, with a reduction to 5000 mcg when I could feel a difference. It’s worked like a champ. My hair is still straw like but it’s full and I’m told the texture will get better. I use shampoo every other day where it used to be everyday. If I can get away with it it’s every 3 days. The unintended consequence of biotin is my nails grow like weeds and I’m a short nails person. Good luck to you. It’s very challenging to lose one’s hair like this.
