Dhi punch vs fue punch?

At times companies or practices advertise what they use as the best option around. And they might be right. In their hands that device or punch may have been better than others. However, I believe a surgeon should have a variety of punches and devices to be able to chose the best for each specific hair and patient.

In general, the smaller the punch the smaller the scar left behind.  However there is a limit to it and going too small may increase the risk of transection (losing some of the hair shafts in each graft) The most commonly used punch sizes are 0.8 and 0.9 in our office. However it all depends on the hands of the user. We switch between sharp and blunt punches and different sizes in addition to manual, motorized and robotic for the best result. The choice of the punch depends on your hair and the physician using it as it is not a “one punch fits all”.

it's just a punch. 1mm or less. FUE of any type involves the use of a punch that's 1mm or less. With ARTAS, the harvesting is either with an 18 gauge needle or a 19 gauge. There's is no real difference in scarring, but those harvested with the smaller needle might heal a day faster (2 days instead of 3)! So, no difference.
