Hi Dr. Rassman.
Why doesn’t the surgeons use a small needle? I have seen needles reported down to 0.4-0.6 mm. This should be good for less scarring in the donor area.
One doctor proclaims that he does hair multiplication and he also claims that he uses less invasive surgical instruments.
Be careful not to believe everything you read. A 0.4mm punch for follicular unit extraction (FUE) is very difficult and I would doubt repetitive in each grafts. I would like to see the results he gets and examine the grafts before I believe what I am told. I have done this on a number of occasions, and you would be amazed at what I found.
