And why does DEKA Motus Pro deliver the best results?

Laser hair removal is one of the most popular beauty services in Latvia. People choose this procedure to achieve long-lasting smooth skin and to free themselves from daily shaving or painful waxing. However, even though Laser hair removal provides long-lasting results, it is important to understand how it works and Why the choice of laser hair removal device significantly affects effectiveness.

In this article, you'll learn:

  • Why doesn't the hair disappear completely after laser hair removal,
  • What biological factors influence the result,
  • why DEKA Motus Pro is one of the best options on the market,
  • and how to achieve the fastest and most lasting results.

Why doesn't the hair disappear completely after laser hair removal?

Laser hair removal works by having the laser beam absorbed by melanin (the pigment in hair), which heats up and deactivates the hair follicle. This stops hair growth, but this isn't possible for all hairs at the same time, since they grow in different cycles.

The hair growth cycle consists of 3 phases:

  1. Anagen (active) – the only phase in which the laser can destroy the follicle.
  2. Catagen (transitional) – The hair separates from the root.
  3. Telogen (resting) – A hair falls out and a new one begins to grow.

At one point only 10–20% strands is in the anagen phase, so a course of treatments is necessary.

Similarly, over time, hormonal changes or biological processes can activate “dormant” follicles, and individual hairs may regrow. These are usually:

  • thinner,
  • lighter,
  • less common.

Biological factors that influence the results of laser hair removal

To ensure that laser hair removal is as effective as possible, the following factors should be taken into account:

1. Hormonal Status

It plays a significant role in hair growth. The following factors can influence the results:

  • PCOS,
  • thyroid disorders,
  • pregnancy and the postpartum period,
  • hormone therapy.

2. Genetics

Measures hair thickness, density, and follicle activity

3. Skin Type

Skin with more melanin can absorb some of the laser energy → appropriate technology is required.

4. Follicle Depth and Anatomy

Some areas (bikini line, underarms, face) are more biologically resistant.

5. Medications and Medical Conditions

Some medications can stimulate hair growth or affect pigmentation.

Why does the quality of the 70% device determine the results of laser hair removal?

Not all laser hair removal devices are the same. They differ in the following ways:

  • laser wavelength,
  • power stability,
  • cooling of the equipment,
  • the accuracy of the technology,
  • level of comfort.

The results can vary significantly if the procedure is performed using outdated or underpowered equipment.

And this is exactly where it proves itself DEKA Motus Pro.

Key benefits:

1. MOVEO Technology – Nearly Painless Laser Hair Removal

Unlike traditional lasers, the Motus Pro laser handpiece glides across the skin as it moves, evenly heating the hair follicles. This ensures:

  • significantly less pain,
  • a lower risk of burns,
  • a shorter procedure time.

2. Effective for both light and dark hair

Motus Pro uses 755 nm Alexandrite and 810 nm Diode wavelengths—which is why it is also particularly effective:

  • plans,
  • for lighter-colored hair,
  • sensitive areas.

3. Safe for all skin types (I–VI)

Thanks to its improved cooling system and technological precision, the Motus Pro can be used safely even on darker and tanned skin.

4. Faster results with fewer procedures

The energy output and stability allow for the destruction of more follicles in each session, so:

  • the effect appears sooner,
  • fewer procedures are required,
  • The hair grows back sparsely and thinly.
