Scalp Micro Pigmentation – A New Way to Fuller-Looking Hair and Greater Confidence

What is SMP?

SMP, or Scalp Micropigmentation, is a widely popular hairline tattooing innovation. It is a technique that creates the natural-looking illusion of denser hair and a fuller scalp. Special pigment is carefully tattooed into the scalp to resemble hair stubble. It is ideal for people experiencing hair loss, thinning hair or baldness who want a non-surgical solution with fast results.

SMP is a procedure in which a specialist uses an ultra-fine micro-needle to precisely deposit biocompatible pigment into the epidermis of the scalp. The pigment is applied as tiny dots that mimic natural hair follicles, creating the illusion of a scalp with hair stubble and adding density to thinning areas so they look fuller.

Who is SMP suitable for?

  • Men and women with hair loss, thinning hair or baldness who want to create a new hairline or add density to thinning areas
  • People who want to conceal scars on the scalp, such as scars from hair transplant surgery (FUT, FUE) or from accidents
  • People who want to refine their hairline so it looks natural and balanced with their face shape
  • People who do not want, or are not able, to have a hair transplant – SMP is a non-surgical option with no long recovery time
  • People who want low maintenance without needing lots of special hair care products

Benefits of SMP

  1. Natural-looking results: The tattooing technique mimics hair follicles, giving a realistic close-shaved look or naturally denser-looking hair
  2. No surgery: A safe, virtually painless option with no surgical risks
  3. Fast, immediate results: Results are visible from the very first session and become complete once all sessions are finished
  4. Boosts confidence: Helps people with hair loss feel confident about their appearance again
  5. Effective scar camouflage: SMP can be used to seamlessly disguise scars on the scalp
  6. Easy to maintain: Once completed, aftercare is simple and no expensive hair care products are needed

Precautions and Considerations

  1. Does not regrow hair: SMP only creates a visual illusion; it does not stimulate real hair to grow back
  2. Touch-ups are required: The pigment may fade over time (on average after 2–3 years), so you may need to return for a touch-up to keep it sharp and natural-looking
  3. The importance of an expert: Choosing an experienced, skilled and well-trained SMP practitioner is essential for beautiful, safe and natural results
  4. Hygiene: Choose a clinic or studio that meets hygiene standards and uses clean, properly sterilised equipment to prevent infection
  5. Allergic reactions: Although biocompatible pigment is used, some people may still have an allergic reaction. Please inform the specialist of any allergy history
  6. Aftercare: Strictly following the aftercare instructions is essential for the pigment to last and to achieve the best results

The General SMP Process

Consultation and design :

The specialist assesses your scalp, discusses your expectations and designs a hairline that suits your face shape and age, and selects a pigment shade that matches your natural hair and skin colour

Scalp assessment during SMP consultation

Preparation :

Your hair may be shaved short (for a shaved look), and certain medications that may affect blood clotting should be avoided

Tattooing sessions :

Usually 2–4 sessions, spaced about 7–14 days apart, to allow the scalp to heal and the pigment to settle. A numbing cream is applied to reduce discomfort

Micro-needle cartridges used for SMP

Aftercare :

Avoid getting the scalp wet, strenuous exercise and direct sunlight for the first 3–5 days so the pigment can set and the scalp can recover

How to Prepare for Your SMP Treatment

To get the best possible results from SMP and reduce any risks, preparing in advance is an important step you should not overlook:

Consultation and design:

  1. Scalp assessment: The specialist will assess the condition of your scalp in detail
  2. Share your goals: Clearly tell the specialist your expectations and the results you want
  3. Hairline design: Work together to design a hairline that suits your face shape and age
  4. Shade selection: Choose a pigment shade that matches your natural hair and skin colour

Preparing your body:

  1. Shave your hair short: If you want a close-shaved look, the specialist may recommend shaving your hair short before the appointment
  2. Avoid certain medications: Consult your doctor or SMP specialist about stopping medications that may affect blood clotting, such as aspirin or blood thinners, before your SMP treatment
  3. Avoid alcohol and caffeine: Avoid these drinks for at least 24–48 hours before treatment, as they may affect blood circulation and skin sensitivity
  4. Get plenty of rest: A good night’s rest before your appointment helps your body relax and be ready for the procedure

Scalp care:

  1. Keep it clean: Wash your hair and cleanse your scalp thoroughly before the appointment
  2. Avoid irritation: Do not use styling products or chemicals that may irritate the scalp before the appointment

Good preparation helps your SMP treatment go smoothly and safely, so you get the most satisfying results.

THB 250 / square centimetre (cm²)

Our SMP pricing is based on the size of the scalp area being treated, at THB 250 per square centimetre (cm²). This allows us to tailor the price to your individual treatment area rather than charge a fixed full-head price. During your in-person consultation, we will assess and measure the treatment area, then confirm the number of sessions included and the final total price with you before you decide to proceed.
