How can I conceal my donor scars from a hair transplant if I want to shave my head?

You can hide donor scar with scalp micropigmentation SMP. See video of how it looks after SMP. It is a non surgical procedure.FUE still leaves a scar and SMP can hide FUE scar as well.  It does not matter if FUE was ARTAS robot or Neograft or Manual or Drill 

Depends on what type of scars you are talking about.  If you have not had a procedure yet then only consider FUE as the scars are almost invisible to the naked eye.  If you already have a strip scar then tattoo with skin pigments can help but it is almost always going to be noticeable.  Scar excision with the Neograft can help as well.  Good luck

Hi MIKEFJ, You may also consider a follow up follicular unit transplant via FUE. New robotic technologies are available, and they ensure donor hair extraction is conducted in a diffuse yet precise manner that shows virtually no sign of extraction. After extraction, the surgeon can use the extracted donor hair to camouflage donor scars. Consult a surgeon for more information on this process and, if possible, request to see specific before and after images that demonstrate a natural-looking outcome.
