Hi, I am on dialysis and have noticed a little bit of hairloss. My hair used to be very thick now it's really thin and every time I brush a pile comes out. I'm a liver recipient (5 years now) and I'm on prograf 3 miligrams twice a day. I'm also on prednisone 5 miligrams once daily. What could be causing it? and how can I stop my hair from falling?
