Some types of hair loss from kidney disease are reversible whereas others are not. It all comes down to the reason for the hair loss and the reason for the kidney disease. Be sure to see a dermatologist to guide you further. I don't have enough information from the question to give a more definitive response.Here are just two of 100's of examples;A patient might experience temporary hair shedding episode from an infectious glomerulonephritis that caused fever, pain, and kept them in bed (or hospitalized) for a few days or weeks. Once the glomerulonephritis is treated shedding will slow down and resolve in 6-9 months.A patient might experience a variety of hair loss patterns if his or her kidney disease is from "lupus" of the kidney (lupus nephritis, etc). Such a patient could have both scarring and nonscarring hair loss and the former would be permanent hair loss.All in all, if you are worried about hair loss and have kidney disease, be sure to meet with a dermatologist who specializes in hair problems.
