I am interested in a hair transplant, but I had shingles 4.5 years ago with a rash on my neck and scalp, exactly in the donor area. This resulted in postherpetic neuralgia (PHN), causing pain and a burning sensation. Haircuts and wearing a hat were painful due to allodynia. Over the last year and a half, the pain has mostly disappeared, but occasional flashes of pain indicate the area is not fully healed. Can I consider a hair transplant, or is there a risk the pain could return or worsen?
