Techniques & Tools Flashcards

Which needle configuration is most commonly used for SMP to replicate individual hair follicle dots?

Answer: Single needle (1RL)

A single needle (1RL) creates the precise, small dots that mimic individual hair follicles in SMP.

What is the primary purpose of using a rotary machine over a coil machine in SMP?

Answer: It produces less vibration for more consistent dot placement

Rotary machines produce less vibration and noise, allowing more precise and consistent dot placement ideal for SMP.

When performing SMP on a client with a grade 1 buzz cut, what dot size should the practitioner aim for?

Answer: 0.8–1.2 mm

Dots between 0.8–1.2 mm closely replicate the cross-section of a shaved hair follicle at grade 1 length.

What technique involves layering multiple sessions to gradually build pigment density in SMP?

Answer: Progressive layering

Progressive layering builds density across sessions, reducing the risk of over-saturation or unnatural appearance.

Which cartridge needle tip geometry best prevents over-saturation when working on the hairline in SMP?

Answer: Single round liner (1RL)

The 1RL tip delivers the smallest ink deposit, minimizing over-saturation risk at the delicate hairline.

What is the recommended machine voltage range for SMP when using a rotary pen?

Answer: 3–4 volts

A voltage of 3–4 volts is standard for SMP rotary pens to achieve controlled, shallow pigment deposits.

Which tool is used to measure and map hairline placement symmetrically before beginning an SMP procedure?

Answer: Caliper or ruler with facial proportion guides

Calipers and facial proportion rulers ensure the hairline is symmetrically mapped relative to facial features before SMP begins.
