Evolved Hair’s Published Donor-Regrowth Study: The Science of Partial Transection The long held industry standard when it comes to hair loss surgery has been black and white: once you take an FU from your donor hair, it is gone forever. An FU is extracted from the safe donor zone (which is the donor hair on the sides and back of the scalp), and that’s the end of it. The once FU, once extracted leaves a microscopic scar at its vacated spot, reducing donor hair density by that amount for good. That has always been the case with Standard FUE.
This presents a frightening prospect for people who need really substantial coverage, and for young men who have an aggressive male-pattern hair loss progression, where there’s a greater chance that, at some stage, you’ll run out of available donor hair. “So, what happens next?” the patient asks? Eventually, the patient simply requires so many hair transplants, that there’s no donor hair left from which to draw FUs for transplantation.
Instead of adopting the ethically dubious and often visible approach of mega-session harvesting, which can leave the patient with a sparse appearance in the donor area, the medical and surgical team at Evolved Hair took a different path. It pursued the efficacy of partial transection and the body’s own natural stem-cell regenerative powers in donor hair follicles. Paul M. Green, one of the research physicians at EvolvedHair, led the study.
Here is an overview of the publication and the scientific fundamentals that have changed the field of hair transplant surgery and Evolved Hair’s approach, forever:
The Science Behind How Hair Follicles Regenerate To understand how your harvested follicles can regenerate on their existing site, or produce a new hair shaft at the site of transplantation of the extracted FU, we first need to know the basic science of a hair follicle. Rather than being a simple ‘plug’, a terminal hair follicle is a miniature organ comprised primarily of two regenerative “nexus” – a collection of highly concentrated stem cells used for cell proliferation:
1. The Follicular Bulge: This is an area in the uppermost 1/3rd of the hair follicle just below the entry of the arrector pili (the muscle that causes goose bumps). The Bulge contains key stem cells, essential to managing the hair cycle,and rebuilding the follicular structure.
2. The Dermal Papilla: Located at the base of the bulb of the hair follicle, this area of mesenchymalcstem cellscommunicateswiththestem cellsinthe Bulgeand regulates the growth pattern and size of the hairshaft to be produced by the stem cells.
Traditionally, the surgical teaching was that any sort of inadvertent slicing, nicking, orcutting (transection)duringa follicular unit extraction would render that FUnotransplantableandun-viable. However,as our understanding of the incredible regenerative powers within biology – and especially within stem cells – has advanced, partial transection (at certain known levels of the Bullage or DermalPapilla of the Follicle) of an FU has proven to fully be transplantable and Viable for both new donor growth and hair transplant!
The Details of Evolved Hair’s Donor-Regrowth Study: Rather than being content with mere theory, the talented team of medical doctors, surgeons and researchers at Evolved Hair, led by Dr. Paul M. Green, conducted a meticulously controlled clinical trial to document dual site regenerationthroughpartial transection.
The Procedure: At Evolved Hair, a state-of-the-art, patented, length-limited device is used to ensure the controlled partial transections required. The surgeons carefully ensure that at least a 1/3rd base of the Fu remains within the donor scalp,leaving the body adequate cells to trigger growth.
The Follow Up & Monitoring Process: To meticulously document every development, areas targeted for partial transection were labelled using advanced microscopic technique,and often micro-tattooing,for precision. These sites were closely documented with advanced optical imagery and macro-photography every 3months over the following year.
Confirming the Science With Results: After the documented regrowth had a chance to progress, a sample selection of these pores were excised, and the biopsy’s were assessed by researchers at the cellular level to confirm successfully regenerated follicles that could successfully produce hair.
So, What does dual site regenerationviacontrolled partial transectionmeanforthe Patient? The groundbreaking results of this peer reviewed study have now revolutionized hair restoration surgery in the following critically important ways for our patients:
Actual Donor Preservation: By ensuring a substantial percentage of each donor FU remains in place for regrowth, your overall donor hair density reduces far more gradually and you can retain a far more generous and usable donor hair supply for future procedures.
Long-Term assurance for Young men and Progressive hair loss sufferers: If you are prone to aggressive hair loss, as you get older you can be assured that you will not have run out of donor hair to fill in any additional areas that may be required to keep you looking youthful.
Eliminates the ‘Moth Eaten Look’ of donor sites: Rather than giving you a visibly sparse or ‘moth-eaten’ appearance across your donor zone as is the case with standard or mega FUE harvests, dual site regeneration helps retain more natural follicular architecture and a far less noticeable impact on the look of your donor hair.
Optimising Results with Added Support: In conjunction with Partial Transection, our patients often benefit from additional regenerative therapies such as PRP (Platelet-Rich Plasma) andPRF (Platelet-Rich Fibrin), which greatly assist in amplifying healing and boosting overall growth in both existing and new donor sites at Evolved Hair.
This commitment to exploring new frontiers in hair transplantation technology goes above and beyond the operation itself. At evolvedHair, we aim to empower you to have great hair, throughout your whole life.
