As of today, it calculates the hair miniaturization index (HMI), meaning the hair that is miniaturized in a particular cm2 surface area. However, this gets tricky with patients that are still losing hair like diffuse hair loss patterns or lower Norwoods. It may pick up the natural progression of miniaturization that isn’t indicative of a poor result. But I believe in the future it will be able to count all the hairs to the number.
At that point, it’s off to the races IMO. Because then you will be able to have undeniable data about the success of the result. It will undoubtedly help patients and surgeons. For those surgeons who achieve high success but find patients still dissatisfied, they will have data to support the success of their procedure. On the other hand, patients will be able to present their case of dissatisfaction with proof if the growth is subpar. No more guessing. But it’s still a ways from that.
