Scalp micropigmentation uses a fine needle to place thousands of pigment dots into the upper dermis of the scalp, matched to your hair colour and skin tone. The result is the appearance of a shaved head with a full hairline, added density under thinning hair, or concealed transplant scars. It is non-surgical, does not regrow hair and lasts several years.
Overview
Scalp micropigmentation, or SMP, is a specialised form of medical tattooing that replicates the appearance of hair follicles on the scalp. Using a micro-needle and pigments formulated specifically for the scalp, a trained practitioner places thousands of small dots in layered shades to mimic natural stubble. On a shaved or closely cropped head, SMP recreates a defined hairline and the look of a full head of hair. Under existing thin hair, it reduces the contrast between scalp and hair so thinning is far less visible. It also conceals linear strip scars and FUE dot scars from hair transplant surgery, and can restore the appearance of density in areas affected by alopecia.
SMP does not grow hair or stop hair loss; it is a permanent cosmetic camouflage. A full treatment involves two to four sessions of three to five hours each, spaced a few weeks apart to build density gradually and let the pigment settle. Results last three to six years before a touch-up is needed, as the pigment slowly fades with sun exposure and natural skin turnover. The International Society of Hair Restoration Surgery recognises SMP as an adjunct to hair restoration, and a 2025 case series in the Journal of Cosmetic Dermatology reported high satisfaction and no adverse events across androgenetic and scarring alopecia patients.
TL;DR Summary
Scalp micropigmentation tattoos thousands of tiny dots onto the scalp to mimic hair follicles. It takes two to four sessions of several hours each at $400 to $1,000 per session, and lasts three to six years before a touch-up. It is the most reliable camouflage for a shaved-head look, thinning crowns and transplant scars, but it does not grow hair. Results depend entirely on the artist’s skill in dot size, density and colour matching.
SMP is priced by the area covered. A hairline or small crown area starts around $1,000; full-scalp coverage for extensive hair loss runs $3,000 to $5,000. Most clinics quote a total for the full two to four session plan rather than per session.

SMP is cosmetic and not covered by insurance. Pigment quality, needle depth and colour layering affect whether the result holds its colour over time.
A micro-needle deposits scalp-specific pigment into the upper dermis at a controlled, shallow depth. Dots are placed in varying sizes and tones across multiple sessions, building a three-dimensional impression of follicles that blends with any remaining hair.
Male and female pattern hair loss, receding hairlines, thinning crowns, alopecia areata and other patchy loss, transplant scars, and scalp scars from injury or surgery.
Three to five hours per session. Two to four sessions spaced two to four weeks apart complete the treatment.
Adults with any degree of hair loss. Not suitable during active scalp conditions such as psoriasis flares or acne, for patients prone to keloid scarring, or for anyone with a pigment allergy. Hair transplant patients should wait until the scalp has fully healed.
Mild redness for one to two days. No washing for four days after each session; avoid sweating, swimming and sun for the same period. Back to work the next day.
SMP camouflages the visual signs of hair loss rather than treating its cause. Below are the concerns this treatment addresses, each explained on its concern page.
For men who have lost most of their hair, SMP recreates a full, defined hairline and the look of closely shaved stubble across the entire scalp, replacing the bald appearance with a deliberate buzz-cut style.
When hair is thinning but still present, SMP darkens the scalp between the hairs so the contrast that makes thinning obvious disappears. The result reads as fuller, denser hair without changing the hair itself.
It is considered semi-permanent. The pigment stays in the skin, but it fades gradually over three to six years with sun exposure and skin turnover. A single touch-up session restores it.
When done by an experienced practitioner, yes. Natural results come from varying dot size and shade, matching your existing follicle pattern and designing an age-appropriate hairline. Ask to see healed results, not fresh ones.
Most patients describe mild discomfort rather than pain. Topical numbing is applied, and the sensation is often compared to light scratching. The hairline and temples are the most sensitive areas.
Yes. Scar camouflage is one of the most common uses of SMP. Pigment is placed into and around the scar to match the surrounding density, making strip scars and FUE dots far less visible even with short hair.
Yes. SMP does not affect the follicles or the surgeon’s ability to transplant. Many patients combine the two, using SMP to add density between transplanted hairs.
The scalp is red for a day or two and the dots soften over about a week. Full settling takes around four weeks after each session, which is why sessions are spaced apart.
