Hairs: Some Information

  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.
  3. The hair is not produced continuously by the follicle, but follows a life cycle in which periods of activity alternate with those of rest: anagen (growth), catagen (transition) and telogen (rest).

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.

As treatments performed, in fact, the hair grows less quickly (from 4 weeks at the beginning, to several months afterwards) and increasingly thinner. The US FDA describes laser hair removal as a “progressively definitive ” method.

In addition, it is necessary to avoid waxing, remove hair with tweezers or bleach them a month before epilation.

The setting of the type of laser light, the power and frequency of treatment depend on: the characteristics of the hair (color, stem diameter and density pilifera), phototype , skin and any concomitant diseases lesions.

The session does not cause pain and there is only a slight heat or a feeling of discomfort, similar to a needle puncture. Sometimes, before proceeding to epilation, the operator can apply anesthetic cream in some particularly sensitive areas of the body (face, armpits and groin).

During the procedure, the cosmetic doctor (or qualified beautician) and the patient must wear protective glasses, specific to reduce the eye risk in the retina.

Depending on the area treated, the duration of the treatment varies from 15 minutes to 4 hours ; each laser pulse acts on a surface of about two square centimeters and it seems that after a session there is a decrease in hair growth between 20-35%.

Immediately after the treatment, a redness of the skin appears due to the action of the laser beam, which varies according to the degree of individual epidermal sensitivity. The redness is temporary and disappears after a few minutes.

Cost of Laser Hair Removal in Delhi

The number of sessions varies according to individual cases and the area treated with laser hair removal.

Usually, several appointments required, established monthly or bimonthly. The individual results depend, in fact, on a series of factors, including age, skin type, hair characteristics and hormonal structure.

To remove unwanted hair from the face with laser hair removal, for example, 4 to 6 sessions may be sufficient. In the case of large body surfaces, such as arms or legs, on the other hand, approximately 5-10 treatments required. Typically, between one session and another, there is an interval of 4-6 weeks.

The results obtained with laser hair removal are long-lasting. Especially, if maintenance session repeated once or twice a year.

When to do the sessions?

Laser hair removal sessions performed at least 30–40 days before sun exposure. As they can predispose to the formation of dark skin spots on the treated area.

If laser hair removal carried out on tanned skin, on the other hand, hypopigmentations may occur, the result of damage to melanin.

For this reason, The better to undergo treatment in periods far from summer. In general, when there is the certainty of not getting tanned.

If hyperpigmented spots appear on the skin, creams based on hydroquinone and retinoic acid used, which, as a rule, solve the problem. There is, however, no specific therapy for light spots, which tend to resolve, however, when the tan disappears.

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. This is why it is better to abandon the idea if the hair is light or the complexion is very dark, and, generally, if there is little contrast between hair and skin.

Laser hair removal does not eliminate hair permanently, as the effects of the aesthetic treatment do not last for a lifetime. However, the procedure has the advantage of strongly slowing down hair growth; therefore it allows thinning out waxes or other hair removal systems.

Hair removal with laser hair removal is not 100% total. In general, a treatment that eliminates the hair of the treated area by 80% can be considered excellent. These results maintained for a long time, if regular sessions repeated. Hair that has not been completely removed is however transformed into a thin hair, not visible to the naked eye.

Contraindications and risks

Laser hair removal is not indicated for those who have little contrast between hair and complexion (light hair on light skin. Medium-dark hair on dark complexion etc.), considering the risks of skin depigmentation. In any case, the specialized aesthetic or medical staff will evaluate the possibility of carrying out the treatment. Always for the same reason, it would always be good to do a small test on a small, slightly exposed surface, to ascertain the effects of the laser on your skin type.

risk of laser hair removal

Laser hair removal is a safe technique, which has no contraindications. However, if hirsutism and hypertrichosis secondary to hormonal dysfunctions are present, it is always better to seek advice from your primary care physician or contact a dermatologist. Even moles should always be evaluated before treatment, avoiding treating the skin areas where the melanocytic ones are present, as they are subject to modifications in case of absorption of the laser energy.

Laser hair removal is not indicated during oral therapies with high dose corticosteroids, antibiotics, hormone replacement treatments, immunosuppressive drugs and other photosensitizers (such as isotretinoin for acne ). The risk is that of provoking the onset of skin spots or produce only a temporary effect of hair loss.

Side effects include erythema , which will spontaneously decrease in a few days, the result of too energetic or unprofessional laser treatment.

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.
