What is laser hair removal and how does it go?

Laser hair removal allows you to quickly and effectively get rid of unwanted hair for a period of 1 years to 5 years. The modern high-tech technique is based on the use of light energy, which contributes to the destruction of dark and light hair on the face and body. Its distinguishing features are minimal invasiveness, the absence of pronounced complications and the need for complex rehabilitation, as well as the duration of the results achieved.

Indications for use

Laser hair removal is performed in the presence of unwanted hair on the face and body. Indications for her are dark, blond and blond hair, both dense and thin (fluffy). Depending on their type, the cosmetologist selects the appropriate category of equipment. It should be noted that the technique is suitable for light or pale skin without tanning.

Laser exposure is practiced when other types of hair removal are not possible and you want a long-term effect.


Of course, laser hair removal has contraindications. It is recommended to refrain from the procedure when:

  • pregnancy and breastfeeding;
  • the presence of malignant tumors and other oncological diseases;
  • diabetes mellitus;
  • dark skin or fresh tan;
  • varicose veins (relevant for leg hair removal);
  • mechanical damage (open wounds, cuts) on the skin (relevant for the treatment area);
  • individual intolerance to laser exposure;
  • infectious skin diseases;
  • exacerbation of pathological conditions (allergy, acute viral infections, chronic ailments);
  • hypersensitivity of the skin, a tendency to scarring.

Epilation is not performed until the patient reaches 18 years.

Classic laser types

Now that the indications and contraindications for the procedure are defined, we will specify how laser hair removal eliminates unwanted hair. In the classical sense, light energy acts only on dark hair with colored pigment (melanin). It absorbs radiation and is destroyed, which leads to the destruction of the hair. In addition, the laser is converted to heat and destroys the bulb itself.

Laser hair removal affects only the hairs in the growth phase. To do this, shave the hair for 2 days before the procedure. Unfortunately, part of the bulbs are always at rest; light energy in this case is absolutely useless. To remove them, you must repeat the procedure after 4 – 7 weeks. To achieve the effect, up to 7 sessions are required. The indicated scheme and principle of operation are relevant for lasers of the following type:

  • Ruby. It has a wavelength of 694 nm. Scope – dark hair, fair skin. A distinctive feature is the processing time (1 flash per second), the laser is designed to work with the surface areas of the dermis.
  • Diode. In this case, the wavelength is 810 nm. It is used to remove hair or eliminate excessive stiffness. Scope – dark hair, dark and fair skin (no tan). Generates on 2 flashes per second, affects the deeper layers of the dermis.
  • Alexandrite. The laser wavelength does not exceed 755 nm. The area of ​​use is dark, brown, red hair with light or sensitive skin. This decision belongs to the category of modern and expensive, respectively. It is also used to reduce tattoos, reduce pigmentation.

Advanced Development

Currently, laser hair removal is a procedure available not only for brunettes and brown-haired women, but also for owners of blond hair. In this case, the vessels that feed the hair bulb are destroyed, which ultimately leads to the complete destruction of the hair of any type.

According to a similar scheme neodymium laser with the most significant wavelength (it equals 1064 nm). The scope is light and dark hair on the skin of any type, the risk of burns is excluded in this case, since the laser does not affect the colored pigments in the dermis. Additional indications – the need for treatment of capillaries, scar reduction. The main advantage of a neodymium laser is the ability to generate up to 100 flashes per second.

Preliminary preparations

Preparation for laser hair removal is an easy task. If possible, visit a specialist for a preliminary consultation, which determines the contraindications, and also selects the appropriate type of laser. The next step – the hair should not be removed mechanically (pulling out along with the bulb), but shaved off for at least 3 – 4 weeks before the session. At the time of the procedure, it is necessary to have a hair length of the order of 2-3 mm.

Expected results
