One of the main objectives in Follicular Unit Extraction is to produce the healthiest grafts possible. Abundant surrounding tissue protects follicles from air drying and injuries from surgical tools. Therefore follicular units with more tissue bulk stay healthier. Plus,  they have a better chance of long-term survival. Dr.UGraft™ hair transplant technology has been specifically designed for increasing graft bulkiness to improve hair transplant growth.

How To Get Better Hair Transplant Yield With Bulkier Grafts

Dr.UGraft™  devices include many patented innovative features. These capabilities make it easier to harvest bulkier, better-surviving grafts:

  1. Flared punch tip with cutting axis that fans outward to gather more tissue around the graft
  2. Patented and patent pending graft grip, pull and score features which work together to pull bulky grafts upward and into the punch lumen. This capability prevents impaction, torsion and twisting forces which injure and damage the grafts.
  3. Fluid irrigation system that lubricates the dull inner surface of the punch. This makes it easier for the bulky grafts to slide upward into the lumen as they are being separated from their surroundings. 

Punch Flaring For Increasing Graft Bulkiness To Improve Hair Transplant Growth 

Besides adding hydration, another way to enhance FUE graft bulk is to have a mechanism for gathering more tissue around the grafts.  One of the most common criticisms of Follicular Unit Extraction procedures is that the use of tiny punches increases the likelihood of slivering the outer tissue layers of the hair follicle unit. This can occur when conventional rotary punches cut towards the graft. When the cutting field is reduced in this way, it contributes to slim or denuded grafts. 

The Dr.UPunch i™ is engineered to do the exact opposite. It’s cutting axis fans outward from the tip of the punch, instead of inward.  By doing so, it expands the field of extraction beyond the diameter of the punch.  As the punch rotates, it gathers more tissue around the graft. 


Dr.UGraft’s Fluid Hydration System For Enhancing Graft Bulk

Well-hydrated grafts are bulkier because they contain more fluid.  The exact opposite is true with grafts exposed to air drying and evaporation.  These conditions will greatly impair their ability to grow new hair.

The Dr.UGraft™ Revolution console is an attachable fluid irrigation system, designed to solve this very problem.  It provides an immediate source of physiological fluid in a drip-control fashion right when grafts are being scored, preventing the risk of damage from air exposure.

This technology provides a convenient, ergonomically friendly mechanism for keeping follicular units moist and in their most optimal health. 

Additionally, the fluid helps to create a more slippery surface on the inside of the punch. This helps bulkier grafts slide more easily into the punch lumen, a necessary final step in separating the follicular unit from its original tissue. 

Graft Control Features For Harvesting Better Hair Transplant Graft Quality

A unique set of patent and patent-pending features allow the Dr.UPunch i to grasp, pull and score grafts. This graft control engineering works together with the flaring, directing follicles upward into the punch as they are scored.

Allowing the graft to move upwards helps to separate it from its surroundings more efficiently.  Also, if a graft moves up, there is no chance for it to become buried by the punch. Once this occurs, the follicle unit is completely unusable. 

Expanded Inner Punch Volume For Bulkier Grafts

The Dr.UPunch i™  is built with a greater inner chamber volume. This provides a greater amount of space to house the graft as it ascends into the lumen. More room also prevents tight contact between the follicular unit and the inner wall.  In turn, this avoids the problem of frictional heat damage.

Frequently Asked Questions – Increasing Graft Bulkiness to Improve Hair Transplant Growth

Is it true that strip surgery methods also increase outer hair transplant graft bulk?  Does this approach improve hair transplant growth yield? How does this method compare to Dr.UPunch devices? 

In strip surgery, it is possible to exert more control when cutting around each graft. This is because the harvesting is done under a microscope using the scalpel as their primary tool.  Many strip surgery supporters endorse this approach as being a safer and reliable way to produce better quality grafts. However, on real patients who have had the surgery, there is no conclusive evidence of better graft quality and more successful hair growth yield. In fact, many of these patients experience  growth failure. And later, they have to invest in additional surgery to fix these mistakes. Also, cutting around each follicular unit under microscopes is also likely to expose grafts to evaporation and air drying. By comparison, the Dr.UPunchidevice helps grafts stay protected by enabling more bulk around the follicular unit and keeping grafts hydrated.
