FUE grafts range from one to a few follicles. Transection occurs when the follicles are cut or otherwise damaged during removal. These grafts will not develop and grow after a transplantation.

FUE transection rate, therefore, is a common way to measure a technique's, procedure's, or surgeon's effectiveness; the higher the rate, the less effective a result. Dr. Cole's transection rate averages 3% or under, exceptional within the hair restoration industry. There are a few different factors that effect transection rates:

Instruments or devices have a major role in transection rates. Specialists should replace their punch, the instrument most common for extracting follicles, every 400 to 1000 extractions, as after this amount the blade irrevocably dulls. Punches are both very small and very sharp, making it impossible to resharpen them after dulling. Automated and robotic devices also varying transections rates; ARTAS, for instance, has an average 10% transection rate. Dr. Cole's specialty devices and instruments, Cole Instruments, features the sharpest punches available with a transection rate of less than 3%. That over 500 specialists use CI devices and instruments is a testament to their quality.  

FUE Technique also can effect transection rates. Dr. Cole's namesake FUE variant, Cole Isolation Technique (CIT®), true minimal invasiveness decreases the chance of transections. Both manual and automated FUE techniques have varying transection rates. Results largely depend on a specialist's mastery of a select technique and familiarity with its latest advancements.   

Specialist involvement during the procedure will effect transection rates. Some clinics relegate certain elements, or the whole procedure, to technicians or other surgical staff. This is most common with clinics that offer hair transplantation as a periphery service, or by doctors unfamiliar with specific hair transplant methodology.

Skill and experience of the procedure team can effect transection rates. The specialist should be present throughout the procedure, but the experience of the entire team matters a great deal. Their involvement effects ths successful extraction, storage, and transplantation of follicles.

Specialist experience and qualifications has a major impact. FUE takes years to master, one reason why the method took a decade to grow in availability. A FUE surgeon's results, including transection rate, largely depends on their skill, training, and experience. Experts typically have a transection rate of 5% while less capable FUE surgeons range from 20% to 75%. A specialist of global renown, Dr. Cole is among the first pioneers of FUE. His innovations range from techniques and treatments to specialty FUE instruments. Read more about Dr. Cole.         


Transection occurs when hair bulbs, which generate new hairs, are cut during follicle removal or otherwise receive harm. Avoiding transection is critical, as every patient has a finite amount of donor hair available. Transection rates will depend on the skill of the physician and the precision of the tools they use. Expert physicians typically have a transaction rate around 5%, while less skilled physicians may have rates between 20% and 75%. Dr. Cole’s average transection rate is under 3% and often lower.



Transection occurs in the recipient area when incisions are not made far enough away from the surrounding hairs. If the blade is held at a wrong angle or too much pressure is applied to scalp with a punch device then it can cause transection in the donor area. Transection rate depends upon the skills of a surgeon.
