What causes unwanted colour changes in scalp micropigmentation?

Scalp micropigmentation can look blue or grey when pigment choice, colour matching, implantation depth, skin healing and sun exposure have not produced the intended tone. Older or poorly matched work may also reveal unwanted undertones as it fades. I assess the existing pigment in person before discussing correction, camouflage or laser removal.

Why can scalp micropigmentation turn blue or grey?

When someone tells me their scalp micropigmentation has turned blue, I first want to see the colour in natural light and understand how the treatment was carried out. A changed appearance does not always have one simple cause.

SMP pigment is selected to match the client's current hair and skin colouring. The mix needs to sit in the right tonal range, particularly when the hair is grey, very light, red-toned or the skin is darker. If the pigment is too cool, too dark or otherwise poorly matched, it can look blue-grey, ashy or unnatural as the treatment settles and fades.

Pigment can also change visually because of the way it was implanted. SMP is intended to place small dots into the epidermal and upper dermal layers, rather than the deeper placement used for a conventional tattoo. If pigment is implanted too deeply, it may spread and heal as larger, blurred areas. That can make the colour appear darker or cooler than intended.

Sun exposure and the natural ageing and exfoliation of skin can affect how pigment looks over time. The pigment does not wash out with shampoo, but it gradually fades. As different tones fade at different rates, an unwanted undertone may become more noticeable.

Is grey scalp micropigmentation always a problem?

Not necessarily. Grey can be the correct and natural-looking result when it has been deliberately matched to grey or white hair. The aim is not to put a black mark on the scalp. It is to reduce the contrast between the scalp and the hair, creating the appearance of soft follicle shadow or density.

Grey hair needs particularly careful colour matching. A pigment that is too dark may look like an obvious addition, while one with the wrong undertone can read as blue, green or ashy. The correct choice depends on your current hair shade, skin tone and the amount of grey in the hair.

This is also why a treatment that looked suitable when first completed may need reassessing if your hair has lightened or gone grey. A colour adjustment may be possible in some cases, but I would not add new pigment until I have assessed the existing work, its density and the condition of the skin.

What should I do if my SMP is going blue?

Do not try to cover the colour yourself with another tattoo, hair product or permanent makeup treatment. Adding more pigment without understanding what is already present can make correction harder, especially if the original dots have spread or the colour is dense.

Start by gathering any information you have about the previous treatment. The pigment brand or colour, the dates of your sessions, the areas treated and any previous correction work can all help. Photographs taken in daylight may be useful, but they cannot replace an in-person assessment.

During a consultation, I look at the colour, spacing, edges, hair pattern and skin. I also ask what you want to achieve now. Some people want the existing result softened. Others want it removed before considering a new design. If the colour is only mildly cool and the application is stable, a carefully planned correction may be considered. If the pigment is too dense or has spread, removal or fading may be the safer first step.

Can laser removal help with blue or grey pigment?

Laser removal can remove or lighten SMP, including unwanted previous work, but it is not something I promise to complete in a particular number of sessions. The response depends on the pigment used, how deeply it was placed, how much pigment remains and your individual skin.

Removal is often considered when the colour has shifted significantly, when the dots have blurred, or when there is too much existing pigment for a natural correction. Laser treatment breaks down pigment so the body can clear it gradually. The scalp then needs time to settle between treatments, and the colour may change during that process.

There can be complications if the original application used unsuitable pigments or if the pigment was implanted too deeply. That is why an assessment is important before treatment begins. Laser removal is available at Simply Scalp, and I hold a Level 5 Laser Tattoo Removal qualification, specialising in SMP removal. I remain personally involved from consultation through treatment and aftercare.

Laser removal does not regrow hair or recreate a receded hairline. It lightens or removes cosmetic pigment. If you later choose a new result, the design would be planned around your current hair pattern, facial structure and expectations.

How can I reduce the risk of SMP changing colour?

The best protection is careful planning before the first needle is used. I recommend choosing a licensed and experienced practitioner, reviewing healed work rather than only fresh photographs, and asking how pigment will be matched to your hair and skin.

A thorough consultation should cover your medical history, allergies, skin, hair loss pattern and expectations. Before treatment, your hair and scalp should be clean. The treatment area should be marked, and the proposed hairline should be discussed. For someone with complete hair loss, facial structure and age are important considerations when planning a believable hairline.

It is also worth asking how the practitioner approaches pigment depth and spacing. Natural SMP should leave some visible scalp showing through. It should not look like a solid painted surface. A controlled application helps preserve separate follicle impressions rather than allowing them to merge into a block of colour.

After treatment, follow the personalised aftercare instructions you are given. General guidance includes keeping the scalp dry during the healing period, avoiding heavy exercise, steam rooms and hot showers that cause sweating, and avoiding direct sun for several days. Once healed, long-term broad-spectrum sunscreen can help protect the pigment from UV exposure.

I work directly with every client at Simply Scalp in Purley, South London. The practice is intentionally small, so I do not delegate consultations or treatments. If you are a woman, or your hair loss pattern is diffuse, you may also wish to read about SMP for women before arranging an assessment.

When should I seek professional advice?

Arrange a consultation if the colour has changed quickly, the dots look blurred, the scalp is persistently uncomfortable, or you are unsure whether the result is healing normally. Contact your practitioner promptly about unusual redness, warmth, swelling, discomfort or any concern that goes beyond what was discussed at consultation.

Most importantly, avoid making a rushed correction based on the colour alone. I need to understand the pigment, skin and design together before recommending a route forward. Sometimes the right answer is a gentle adjustment. Sometimes it is staged laser fading. Sometimes the result needs time to settle before any decision is made.

If you would like to talk through your existing SMP, you are welcome to book a consultation with me.

Frequently asked questions

Can blue SMP be corrected without laser removal?

Sometimes, but it depends on how strong the colour is, whether the dots remain separate and how much pigment is already present. Adding more pigment can make an overworked or deeply implanted result worse. I would assess the scalp first and explain whether correction, fading or removal is the more sensible option.

Why does old SMP sometimes look green as well as blue?

Some pigments can reveal different undertones as the skin and pigment particles change over time. The original pigment mixture, implantation depth, fading pattern and sun exposure may all contribute. Green or blue colouring should be assessed rather than covered immediately, because the safest correction depends on what remains in the scalp.

Will washing my hair remove unwanted SMP colour?

No. SMP pigment is designed to remain in the skin and will not wash out with ordinary shampoo. It does fade gradually through natural skin processes, but washing more often is not a safe removal method. Harsh products or scrubbing may irritate the scalp without removing the underlying pigment.

Can SMP be matched if my hair has gone grey since treatment?

It may be possible to plan a colour adjustment, but the existing pigment must be assessed first. Grey hair requires a careful tonal match so the result resembles soft follicle shadow rather than a visible mark. If the previous pigment is too dark or has changed colour, lightening may be considered before adding anything.

Does laser removal of scalp pigment hurt?

Discomfort varies according to the person, pigment and area being treated. I explain what to expect during consultation and discuss suitable comfort measures. The scalp also needs time to settle after treatment. I do not promise a fixed removal timetable, because pigment and skin respond differently from one client to another.

Can a new SMP treatment hide a blue hairline?

It may be possible, but camouflage is not automatically appropriate. A blue hairline may indicate excess pigment, an unsuitable undertone or pigment spread. Placing more colour over it can increase density and make later removal more difficult. I would first assess the hairline, existing pigment and your preferred appearance before discussing a new design.

What should I bring to a corrective SMP consultation?

Bring details of previous treatment dates, the practitioner if known, pigment information, aftercare instructions and any photographs showing the result over time. Tell me about allergies, skin conditions, medication and previous laser work. You do not need to shave beforehand unless we agree that doing so will help the assessment.
