Hair transplantation is increasingly sought by mature patients wishing to maintain a dynamic appearance. However, the emergence of grey or white hair (canities) introduces a major technical complexity that few clinics have mastered. At Phoenix Hair Paris, we consider grey hair not an obstacle, but a demand for increased medical precision.
The Biology of Grey Hair: The Absence of Melanin
Canities is not a change in hair colour, but a loss of pigmentation. Hair colour is determined by melanin production by melanocytes located at the base of the follicle. With age, the activity of these cells diminishes until it ceases entirely. The hair then grows without pigment: the hair shaft, devoid of melanin, becomes transparent.
The Technical Challenge of FUE Extraction on White Hair
Graft Transparency
An experienced physician uses high-magnification loupe glasses to visualise the hair emergence angle and the follicle's pericellular structure. On dark hair, melanin provides sharp visual contrast. On grey or white hair, the graft becomes nearly invisible in the dermis, blending with surrounding tissue. The risk of transection (accidentally sectioning the follicle during punching) increases considerably if the physician does not adapt their technique.
Graft Fragility
Depigmented follicles are slightly more fragile and less tolerant to ischaemia than pigmented follicles, which benefit from the antioxidant protection of melanin.
The Phoenix Hair Punch Technique Expertise for Grey Hair
A. Manual Micro-FUE and Hybrid Punches
Aggressive motorised extraction is prohibited on white hair. Our physicians favour manual FUE or low-speed hybrid punches. These ultra-sharp instruments limit torsion and friction forces during penetration, drastically reducing transection risk even on transparent grafts.
B. The Art of Punch Angulation
Extraction is not a vertical gesture. Each hair has a unique emergence angle. On white hair, this angle is more difficult to perceive. Our physicians' expertise lies in their ability to "sense" tissue resistance and instantly adjust the punch inclination to follow the natural direction of the depigmented follicle beneath the skin.
C. Visual Contrast (Lighting Techniques)
To compensate for the absence of melanin, we use specific polarised LED lighting systems that enhance tissue texture contrast, allowing us to differentiate the transparent follicle from the pericellular dermis.
