Scalp micropigmentation (SMP) is a cosmetic tattooing procedure that creates the appearance of close-cropped hair through tiny pigment deposits placed at the hair-follicle level. Unlike traditional tattoos, SMP uses specialised pigments designed to fade neutrally over time and equipment optimised for shallow placement. The outcome is the visual appearance of a uniformly shaved head, which, in the right patient, can be cosmetically superior to alternatives like wearing a wig or undergoing transplantation with insufficient donor density.

The procedure typically requires 2–4 sessions spaced 1–4 weeks apart, with total costs ranging from £1,500–£4,500 depending on coverage area and practitioner. Recovery is rapid, mild scalp redness for 24–48 hours after each session. Results typically last 4–8 years before touch-ups are needed; the pigments fade gradually rather than turning blue or green like older traditional tattoo inks. Selection of a practitioner with hair-loss-specific experience is critical because the pointillist technique differs substantially from conventional tattooing.

SMP is best suited for patients who are willing to commit to a buzzed haircut style and want the cosmetic appearance of a defined hairline and uniform scalp coverage. It can be combined with hair transplantation to fill density gaps between transplanted grafts. It also works well to camouflage transplant scars (FUT linear scars or FUE dot scars) in patients who later choose to wear their hair very short. For patients with advanced Norwood 6–7 hair loss without sufficient donor reserves for transplantation, SMP is often the most realistic path to a satisfying cosmetic outcome.
