Comparing SMP Hair Pigmentation Needles vs other small objects, including a human hair follicles.

Scalp Micro-pigmentation (SMP) has gained tremendous popularity as a non-surgical hair loss solution. It involves depositing pigments into the scalp to mimic the appearance of hair follicles.
One crucial aspect of SMP is the needle size, which plays a significant role in achieving a natural-looking result.

Hair pigmentation artist are working on a precision level that resembles the technical skills of reputable hair transplantation surgeons and even micro surgeons!
To produce consistent good looking, natural looking hair pigmentation results it requires extremely well-coordinated hand eye coordination.

The Thickness of SMP Hair Pigmentation Needles:

SMP hair pigmentation needles come in various thicknesses, typically measured in mm.

The most commonly used needle size for SMP range from 0.15 to 0.25 mm. Please note that typically the tiny holes that are created shrink about 50% afterwards, thus reducing the dots to about 0.07-0.12 mm which is about the diameter of a human hair.

To put this into perspective, let's compare it to some other small objects:

 A Ballpoint Pen Tip:

The average ballpoint pen tip measures around 0.7mm, making it significantly thicker than an SMP needle. The difference in size highlights the delicate nature of SMP hair pigmentation.


A Strand of Human Hair:

On average, human hair has a diameter of about 0.06mm to 0.12mm.

Hair transplantation instruments

A typical FUE hair transplantation ‘needle’ is about 0.70-1.00 mm diameter.

These instruments are used only be the most experienced surgeons worldwide. Making smaller needles has little advantages since it would not allow for a full extraction from an 3-4 bulb hair follicle. On the other hand using larger needles just would cause more skin damage.

A Grain of Salt:

A grain of table salt measures approximately 0.3mm to 0.6mm in diameter, which is thicker than most SMP hair pigmentation needles. This comparison showcases the precision required in SMP procedures.

The size of SMP hair pigmentation needles plays a crucial role in creating natural-looking results.

Their fine diameter and varied tip configurations allow for precise pigment placement, mimicking the appearance of hair follicles.

When compared to small objects like ballpoint pen tips, hair transplantation instruments, grains of salt or even strands of hair, SMP needles are considerably thinner. This highlights the meticulous nature of SMP procedures and the level of detail required for a successful outcome.

Understanding the size of SMP needles can help individuals appreciate the artistry and precision involved in this innovative hair loss solution.
