A crown hair transplant uses the FUE (follicular unit extraction) technique to harvest individual follicular units from the back and sides of the scalp, where hair is genetically resistant to DHT, and implant them precisely into the thinning or bald area at the top of the head.
Unlike the hairline, where grafts are placed in a relatively simple plane, the crown requires the surgeon to replicate the natural vertex whorl. Every patient has a whorl point at the crown from which hair radiates outward in a circular pattern. Grafts in the centre of this whorl must be placed at a near-perpendicular angle, while follicles placed further from the centre shift progressively to a flatter angle and a changing rotational direction. Getting this wrong produces a result that looks transplanted regardless of density.
A second challenge unique to the crown is the density illusion. The crown sits on a curved surface, and photographs or mirrors compress the apparent size of the thinning zone. In clinic, the actual surface area is almost always larger than the patient expects. A moderate crown patch, roughly coin-sized in a mirror, typically requires 1,500 to 2,500 grafts to achieve adequate coverage. More advanced crown loss can require 3,000 grafts or more, often across two sessions.
All FUE hair transplants at Harley Street Hair Transplant Clinics are carried out by GMC-registered doctors in CQC-registered clinics, with no delegation to unlicensed technicians at any stage.
