Hairline Tattoo in Hongdae, CYAN
When people look for a hairline tattoo in Hongdae, what really matters is how balanced the face looks. The forehead line is where facial proportion begins, so even a small adjustment shifts your whole impression. CYAN's hairline tattoo fills in a forehead that reads as broad, or an angular M-shape, with soft powder shading — lowering the line as if fine baby hairs had been drawn in, to tidy your facial proportions. It tends to suit people who want to stop always hiding the forehead behind bangs, or filling it in with powder every morning.
Hairline tattoo and scalp micropigmentation (SMP) are often confused, but they do different jobs. A hairline tattoo fills the forehead boundary with soft powder shading to lower the line and tidy the shape of your face, while SMP places follicle-like dots across the scalp to build the impression of density where hair is thinning. Whether you want only the forehead line refined, or the empty look at the crown and part line filled in too, changes the approach — so we settle it together in consultation.
Even the same hairline calls for a different line depending on your forehead width, face shape and natural hair flow. Setting it too low or too straight can actually look unnatural, so following the angle at which baby hairs naturally grow as we add the shading gives a more natural result. What stays on the forehead is pigment — but what stays with people is the impression, so we draw the line on, check it together in the mirror, and only proceed once you agree.
Needles and consumables are single-use, and the treatment space is kept sanitized. The shading that looks dark right after the session fades as the scabbing lifts, and we usually refine the line and depth with a touch-up (retouch) around 6–8 weeks later. How long it lasts varies from person to person with skin oiliness, sun exposure and aftercare, and if it fades we refine it with a touch-up.
How the edge is built
A natural hairline comes from a soft, diffused edge rather than a sharp one.Drawn as a clean line, the front row shows immediately from straight on, so the front is left sparse so it reads like baby hair.
Height and shape are set against your face shape and left-right asymmetry.A guideline is drawn before anything starts and checked together from the front, at an angle, and with the hair pushed back — we work only inside the line you have agreed to.
How far the forehead can come down
This is answered more accurately in front of a mirror than with a number.The distance to the brows and where your own baby hair used to sit define the limit that still reads natural, and going past that limit looks less natural by exactly as much as it gains.
For filling M-shaped recession, the key is matching the colour and spacing of the dots to the hair that remains, so density is built across sessions.Tell us in the consultation about any scalp condition or medication you are taking.
How the fine hairs are drawn in
What makes a hairline look real is not the shape of the edge but the fine hairs.A natural hairline is never cut straight; short, thin hairs scatter irregularly along the edge.Leave that out and build only a line, and it reads as artificial up close.
So beyond the edge we deliberately drop the density and scatter the work.The spacing is not kept even, and the direction shifts slightly to follow the flow of the hair inside.Place them regularly and the regularity itself is what the eye catches.
If you still have fine hairs of your own, we take their direction as the reference.Continuing a flow that already exists reads far more naturally than inventing one that does not.
How it looks when your hair is tied up
A hairline shows more when the hair is up than when it is down, so we start the design by asking how you usually wear it.Someone who always ties their hair back and someone who wears a fringe need different areas filled.
Tying the hair back exposes the line at the temples and around toward the nape.Filling only the front of the forehead and leaving the sides empty makes the edge look broken once the hair is up, so we also decide how far along the sides the work continues.
If you always part your hair on the same side, that side usually looks thinner.Rather than filling both sides identically, placing more density where it actually shows gives the more natural result.
The days after, and when the next session falls
A hairline is usually built up across sessions rather than filled in dark at once.The first session is kept light so you can see how it reads on your face, and a second at around six to eight weeks refines the density and the edge.
For the first few days the colour looks strong and the forehead may be slightly red.Skip heavy sweating and saunas during those days, and start washing your hair from the point we tell you.
If you are travelling from another region or from abroad, fitting in the second session may not be practical.We check when you could realistically return while booking the first visit, and if it is difficult we adjust how much ground the first session covers and how deep we work.

Frequently asked questions
What is the difference between a hairline tattoo and scalp micropigmentation (SMP)?
A hairline tattoo fills the forehead boundary with soft powder shading to lower the line and tidy your facial proportions, while scalp micropigmentation (SMP) places follicle-like dots on the scalp to build the impression of density. If you only want a broad forehead or an M-shaped line refined, a hairline tattoo tends to suit you; if you also want to fill the empty look at the crown or part line, SMP does. The two are sometimes done together, so we decide in consultation.
Can an M-shaped or angular hairline be made to look natural too?
The dips of an M-shape or sharp corners can be filled with soft powder shading and eased into a gentler curve. That said, how naturally it can be filled varies with the shape of your original line and your forehead width, so we confirm what is possible after looking at your forehead in person during the consultation.
How much does a hairline tattoo cost?
The cost of a hairline tattoo depends on the area treated — the front line, the sides, whether the M-shape is included — and the state of your forehead. Exact pricing is given in consultation after looking at your hairline, and you can check overall service rates on our pricing page.
When can I colour or perm my hair again?
We suggest waiting until the treated area has fully settled and the colour has taken. Around a month is a reasonable guide, and if you have sessions remaining it is safer to book colouring after the last one. If you already have colouring planned, it is better to do that first and come in for the consultation afterwards, because a change in hair colour changes the tone we need to match.
Can men have this done?
Yes. The purpose is often a little different, though. Rather than bringing the forehead in, we tend to rebuild the edge where a receding corner has cut in, or lift the density along the front line so the area reads less sparse. If crown or overall density is part of the concern, we look at it together with the scalp and decide the area from there.
