What scalp micropigmentation density should I choose?

What does scalp micropigmentation density mean?

Scalp micropigmentation density describes how closely the tiny pigment impressions are placed across the scalp. The purpose is to reduce the contrast between your scalp and existing hair, not to cover the skin with a continuous layer of colour.

For a shaved or closely clipped style, the impressions create the appearance of follicles and a short shadow. For male density work, pigment is placed between existing hairs to make thinning look less visible. The result should still allow some scalp to show through. That is part of what keeps it believable.

SMP is a cosmetic camouflage treatment. It does not regrow hair, alter natural hair growth or damage existing follicles. If you want a broader explanation of the treatment, I recommend reading my guide to scalp micropigmentation before deciding on density.

How dense should SMP be for thinning hair?

For men with diffuse thinning, the appropriate density depends on how much hair remains and how much scalp is visible in normal light. Early or moderate thinning can often be treated with a relatively subtle layer between the hairs. More advanced thinning gives us less natural hair to blend with, so the plan may need to be reconsidered alongside your preferred haircut.

I do not recommend simply asking for the highest possible density. Excess pigment can make the scalp look heavy, especially when the spacing, shade or hairline does not match the surrounding hair. A softer result is generally more flexible if your hair loss continues.

Your everyday hairstyle matters. If you already keep your hair very short, a shaved-style result may be suitable. If you prefer to retain your existing hair, density work can reduce show-through without trying to imitate a fully shaved head. I discuss the difference in more detail in my guide to buzz-cut SMP and added-fullness SMP.

How do I assess the right density for you?

At consultation, I look at the pattern and progression of your hair loss, your natural hair colour, the colour and condition of your scalp, and the length you intend to maintain. I also consider your hairline, crown, temples and side profile. A density plan that looks convincing from the front can still appear mismatched from another angle.

I ask how you style your hair now and whether you may shave closer in future. This matters because pigment that looks appropriately subtle beneath longer hair may look too strong if the hair is later clipped very short. Conversely, a plan designed for a close shave may not blend naturally beneath longer, thinning hair.

Grey hair does not automatically mean that a grey pigment is correct. I match the shade to the hair that remains, your skin tone and the intended hair length. Shade and density cannot be separated. A suitable colour placed too closely can still look unnatural, while careful spacing can make the same general tone appear more convincing.

Is density built up gradually?

I prefer to establish the result progressively rather than attempting maximum density in one appointment. A typical plan uses three sessions, with healing time between them. The first session lays a lighter foundation with wider spacing. Later sessions add density and detail only where the healed result shows that it is needed.

As a general guide, the first layer may be around 40 impressions per square centimetre, building towards approximately 80 to 100 in the final layer. These figures are planning references, not a prescription for every scalp. Skin response, existing hair, treatment area and the intended finish all affect the decision.

I allow the scalp to settle between appointments so I can judge the healed colour and spacing, rather than working over fresh redness or swelling.

What can make SMP density look unnatural?

The most common planning problems are too much pigment, an overly hard hairline, unsuitable shade or insufficient attention to the surrounding hair. Your hairline should be designed for your facial structure and age, not drawn as a ruler-straight border. I pay particular attention to this because the hairline is often the first part other people notice.

Pigment must remain in the appropriate upper skin layer. Too shallow a placement can fade quickly, while excessive depth can cause the impressions to spread and lose their follicle-like appearance. The work should be controlled and clean, with spacing that follows the natural pattern rather than forming a block.

I also want you to consider future change. SMP does not stop hair loss. If your remaining hair becomes thinner, the visual balance may change. A conservative density plan and a hairline that is not excessively low can give you more options later.

What should I expect after treatment?

The scalp can look darker or more intense at first. Redness commonly settles over the following days, while the pigment continues to soften and settle during healing. Lightening is normal, so I ask you not to judge the final density immediately after a session.

For the first four days, keep the scalp dry and avoid shampoo, shaving, sweating and sun exposure. After that, I will give you washing instructions for your treatment. Avoid swimming pools, saunas and steam rooms for 28 days. From day four, moisturising can be introduced as advised, and after the initial period, protect the scalp with SPF 30 to 50.

SMP is not permanent. Pigment gradually fades through skin turnover, lymphatic movement and UV exposure. The timing of a touch-up varies with skin, lifestyle, sun exposure and hair changes, and I discuss it with you at consultation.

Foli Sim has studios in Perth, Melbourne and Sydney, and I am based at the Perth studio. Prices are published on the Foli Sim website, and I can talk you through them at consultation.

If you are considering SMP, you are welcome to book a consultation to talk through a density that suits you.

Frequently asked questions

Can I have density SMP if I still use hair fibres?

You may be able to, but bring your usual routine to consultation. Hair fibres can hide the scalp temporarily, while SMP changes the underlying contrast between scalp and hair. I need to assess the natural pattern without relying on styling products, and you should stop topical hair products during the week before treatment as advised.

Will density SMP suit a receding hairline?

It can, depending on the amount of hair remaining and the condition of the skin. I may focus on reducing contrast around the existing edge rather than creating a new, low hairline. The design needs to blend with your temples and crown, and should remain appropriate if recession continues.

Does scalp micropigmentation work with light or grey hair?

It can be considered for different hair colours, but the pigment is not chosen by hair colour alone. I assess your current hair, skin tone, planned hair length and the amount of contrast you want to reduce. Grey hair does not automatically require a grey pigment.

Can SMP density be removed if I change my mind?

Laser removal may be possible, but it is not something I want clients to treat casually. Removal can be more complicated when pigment has been placed too deeply or has spread. Careful planning, a suitable density and an experienced practitioner are important before any pigment is applied.

What happens if my hair loss progresses after density SMP?

SMP will not prevent further loss, so I discuss that possibility before treatment. A conservative design may give you more flexibility if the visible area changes. Some clients later choose a shorter haircut or further treatment, but the right option depends on how the pattern develops.

Is SMP density painful?

Discomfort is generally mild and short-lived, although comfort varies by person and area. At Foli Sim, we do not use anaesthetic and advise against it. I explain the sensation, appointment structure and preparation during consultation so you can make an informed decision.

How do I compare density examples online?

Look for healed examples with a similar hair colour, hairline, degree of thinning and haircut to your own. A freshly treated photograph may look darker than the settled result. Ask to see how the work looks from the front, sides and crown, not only in one carefully chosen angle.
