  1. The hairs spread over the whole body surface, with the exception of the palm of the hand. The soles of the feet, the free margin of the lips and some areas of the genital area. Their characteristics (number, shape, length and type) can vary from person to person.
  2. From the anatomical point of view, two main parts distinguished in the hair: stem (evident on the outside of the skin) and root (contained in the hair follicle at the level of the epidermis). In the deepest part, the follicle swells to form the hair bulb, which in turn contains the dermal papilla; the latter structure consists of a group of cells in active proliferation that give rise to the hair.

Laser hair removal in Delhi: how does it work?

Unlike the classic hair removal techniques, which remove only the apical part of the hair, laser hair removal allows you to remove it in its entirety, including the hair bulb.

The principle with which it works is the physical one of light: the laser emits a beam of unidirectional and monochromatic waves, at a frequency such as to selectively hit the melanin contained in the dark-colored hairs on the light complexion, overheating them and denaturing their vital structures (in particular the bulb). If the surgery done correctly, the skin around the follicle remains unaffected.

In laser hair removal, therefore, the hair not torn. But photothermolysis (i.e. the light energy that transforms into heat) causes the destruction of the bulb and the cells that regenerate it. Allowing for long-lasting results.

Laser hair removal has a number of advantages: in addition to being painless, in fact, it promotes a reduction in the quantity and diameter of the hairs, as well as a slow, if not even non-existent, regrowth , thanks to the elimination of the hair bulb.

Limits of the technique

The laser can effectively treat only hair during the anagen phase, since melanin is very concentrated in the hair bulb, especially at this time. For this reason, between one session and the other it is good to avoid the use of waxes and other tear-off hair removal techniques, which interrupt the hair growth cycle.

Laser hair removal guarantees better results on dark-colored hair on a light complexion. On the contrary, for blond, white or bleached hair, the hopes of success reduced, if not zero. Furthermore, it is not advisable to treat skins with a high phototype (V or VI). As they present large quantities of melanin. In this case, the heat absorbed by the skin and not by the hair, resulting in a painful sensation during the session.

Furthermore, after the laser hair removal session, it is important to avoid exposure to the sun, as the skin is particularly vulnerable to the effects of ultraviolet radiation and can react with inflammation of the melanocytes, which will then tend to darken it. On treated areas exposed to sunlight – such as, for example, the face – it is advisable to use a filter with high protection (SPF 50), even in winter.
