Everything you need to know about laser hair removal

Hair removal from any part of the body is a matter of choice for individualistic tastes. But if one chooses to remove it, then there are plenty of options available in the market. The most common types of hair removal include shaving and waxing. Shaving is the cheapest and fastest forms of hair removal that can be done in the shower anytime but for those who have been using this method for a while now know that it can cause razor burns and cuts and knicks during the process as well. The hair also grows back within days, and it's a hassle to shave everything once more. Waxing will prolong the time for the reappearance of hair but its painful and time-consuming just like threading. So the next best option is the laser hair removal process. The laser hair removal cost might be a deterrent for many as it can be quite expensive depending upon the area to be covered and the place it is being done. But the money is well invested. Especially if you are opting for at-home laser hair removal device, then it’s even more convenient.


How does the laser hair removal works?

The primary principle behind laser hair removal is that the concentrated beam of light destroys the hair follicle. The wavelength of the light only has targeted effect on the particular area and not the surrounding tissue. The selective heating does localized damage to the darker pigments called melanin present on the skin. Hence, the darker and coarser the hair, the more effective laser hair treatment will be. As there is selective absorption, therefore only hair with brown, black, reddish-brown and dirty blonde colors will respond better to the procedure. Hair colors such as white, strawberry blonde, and light blonde will not respond well. The ideal combination for the laser hair removal to work is light skin and dark hair. They produce the most effective result. But there are lasers like Nd: YAG laser that is very beneficial for patients with dark skin and dark hair.

Laser hair removal is not exactly a permanent technique of hair removal. According to the FDA's definition "permanent" hair reduction is the stable, long term reduction in the hair growth after the treatment regime. Sometimes patients also have noticed hair growth in the areas treated after years of the last session had been conducted. This implies that the laser hair removal will reduce the total number of body hairs but will not result in the complete or permanent removal of all hair. The laser hair removal whether done at a clinic or done by at-home devices will give more or less similar outcomes, but at-home devices will give lesser laser hair removal cost. The point is that have reasonable expectations from this procedure. The hair follicle might be damaged by the laser therapy resulting in the slowing of the process of hair growth but might not have utterly destroyed the follicles in some cases. However, be assured that the hair won’t grow back like it had done before. The regrowth will be thinner and comparatively less visible.

How many number of sessions are required?

The laser therapy can only affect the actively growing hair follicles as hair grows in several phases. Therefore several sessions are required to force the hair to revert to a vellus non- colored small hair by damaging the hair in all phases of growth. Long term reduction in the growth of the hair has been seen by following up multiple treatments which depend on the type of the skin and hair color. Most patients need a minimum of eight sessions to see the desired results. Depending on the area to be treated it is generally advised to wait between there to eight weeks between sessions. It also depends on the device, whether it's the clinical-grade or the at-home ones in both cases, a waiting period between sessions has to be maintained to let the skin heal. The number of sessions also depends on various parameters such as the skin color, the area being treated, coarseness of hair, gender and reason for hirsute in any. Certain areas like a man’s face might need considerably more treatment sessions to achieve the desired result.

Laser hair doesn’t work effectively or at all on light or thin-haired people. Generally, the shedding of the treated hair takes about two to three weeks. These hairs should be allowed to fall off on their own and should not be manipulated by the patients in any which way possible as there can be chances of infection. Pulling the hair out after the treatment can be counter intuitive and be more painful so it must be avoided at all costs.

Side effects and risks

Certain typically shown side effects are related to laser hair removals like swelling of the follicles or follicular edema, swelling around the treatment area, itching, redness or pink skin, etc. These side effects can persist only for a day or two after which they will subside eventually. The most common serious side effects are skin discoloration and acne. There is a certain level of pain that can be experienced during the treatments. Sometimes for an additional cost, there are numbing creams available as well. Some of these numbing creams are also available over the counter. The cream can be used thirty minutes before the treatment, and ice can be applied to the area after the procedure to lessen the visibility of the side effects. However, if a large area is being treated at a time, then the use of numbing cream must be avoided at all costs as it can be detrimental to health.

To avoid the severe side effects, it is advised first to do thorough research on which clinic or physician, the procedure needs to be done. Always choose a certified technician and read the reviews before investing in their offerings. Even while selecting the at-home laser hair removal devices, the reliability of the manufacturer must be checked as well. With the right awareness and precautions, laser hair removal will be the most effective way to get rid of unwanted hair in the body.
