Can I have a FUE hair transplant whilst on dialysis? Can I have one after a kidney transplant? Or is it a bad idea?

You need to see a doctor first with a proper examination.  Your doctor will give you a recommendation based on your examination.

Your kidneys and dialysis are life-threatening and essential.  Hair  is not nearly as essential and hair replacement surgery is elective.  Plus, you want to make sure your blood clots properly and you can fend off an infection - so wait until the rest of your health is stable.  Hair is not worth the risk!Good luck!

This is a matter of your health and infection risks. You must speak with your physician first, then coordinate the question with a skilled and knowledgeable hair transplant surgeon to get an answer

if you are on dialysis, generally it is not a good idea . you need to get a clearance from your doctor before doing any kind of surgery anyways. If your doctor feels it is not to your benefit in your condition then it is not a good idea.
