Why Some Scalp Micropigmentation Turns Blue (and How to Prevent It)

Clients sometimes ask why a hair tattoo can heal cool—grey-blue or even greenish. The short answer: it’s not that the pigment “changes colour,” it’s usually optics + depth. Here’s a clear, client-friendly explanation from Sharp SMP Birmingham—and what we do to keep your Scalp Micropigmentation looking natural as a long-term hair loss treatment.

The real reason SMP looks blue: optics, not magic ink

When light enters skin, shorter wavelengths (blue) scatter more. If pigment sits too deep in the dermis, light travels farther through tissue before bouncing back—making dark pigment appear cooler (the Tyndall effect).

Result: what should look charcoal/neutral reads blue-grey, especially at the edges or in strong light.

Other optical factors that push tones cooler

• Dot size too big: more light catches the edges, raising the blue cast.

• Dense over-packing: creates a “flat ink field” that reads cooler.

• Cameras & lighting: cool LEDs/white balance exaggerate blue in photos.

Technique mistakes that cause blue tones

1. Depth errors – working below the upper dermis → blur/blue/migration.

2. Excess pressure or slow hand speed – ink pools → oversized dots.

3. Wrong needle/grouping – stamps rather than micro follicles.

4. Trying to “go darker” in one go – over-saturation instead of layered density.

5. Poor blending at hairline/temples – sharp edges + depth = visible cool halo.

Pigments: why the type matters (and what we use)

• SMP pigments are typically carbon-based, single-tone blends designed to heal neutral across skin tones. They don’t “turn blue” by themselves; the skin optics + depth make them look cool if misused.

• Mixed or multi-colour tattoo inks (for body art) aren’t appropriate for SMP—vivid carriers + deeper placement increase the risk of off-tones later.

Prevention: how we keep your result neutral at Sharp SMP Birmingham

• Correct depth control in the upper dermis (shallow enough for crisp dots, deep enough for stability).

• Micro-dots with variation (size/spacing/angle) for true follicle texture.

• Layered sessions (2–3) instead of hard packing in one go—lets tones settle naturally.

• Neutral-healing pigments matched to your undertone (we test-patch before committing).

• Lighting checks (daylight + cool/warm indoor light) during design and blend.

“My SMP looks blue—can it be fixed?”

Usually, yes. The gold standard is to lighten with laser (commonly 1064 nm for carbon) and then re-do at correct depth after healing.

• How many sessions? Varies—small areas can clear quickly; dense over-packed zones take longer.

• Saline removal? Sometimes for small corrections, but laser is more efficient for carbon-based SMP.

• Colour-on-colour “correction”? Rarely advised. Layering warmer tones over a depth error won’t change the optics and can make the area muddy. Best practice is lighten → rebuild properly.

What you should ask any practitioner

• Where in the skin do you place SMP, and how do you control depth?

• Do you build density over multiple sessions?

• Which pigments do you use and why? (Look for neutral-healing SMP pigments.)

• What’s your plan if an area heals too cool? (Laser/lighten, not just over-colour.)

FAQs

Does blue SMP mean the pigment is “bad”?

No not necessarily. It usually means the practitioner has gone too dense or dark or too deep into the skin.

Can sunscreen stop blue?

SPF won’t fix depth, but it slows fade and colour shift, keeping neutrals truer for longer.

Will it get bluer over time?

If it’s a depth/migration issue, it may look cooler as skin changes. Lightening + rebuild is the durable fix.

How fast can I correct it?

Plan a laser course with healing gaps, then a careful SMP rebuild. We’ll map a timeline at consult.
