Can I get a hair transplant if I have controlled epilepsy?

Of course you can.  Epilepsy has no influence on the success of hair transplants unless medications influence hair growth or the medications we use for anesthesia.  I'm not aware of any anti-epileptics that impair transplants or interact with local anesthetics, but ask your physician for an opinion on the use of local anesthetics.  You should do well.  

If your epilepsy is well controlled, you should be able to have a hair transplant surgery.  Your doctor needs to know about your condition.

Good question.  If your condition is under control you should be fine having a hair transplant under local anesthesia.  I would, however, want to speak with your neurologist first to make sure it's a go.  More questions are answered in the attached video.
