When looking for an efficient and more long-lasting way to get rid of unwanted hair, laser hair removal is frequently the first option that comes to mind. You won’t have to worry about making mistakes, missing places, or ingrown hairs in addition to getting silky, smooth skin without the inconvenience of waxing or shaving. It takes expertise from many different fields to understand laser hair removal. This fascinating cosmetic method is influenced by quantum and optical physics, the biology of hair growth cycles, and the traditional and contemporary justifications for hair removal. Laser treatment for hair removal cost hence depends on the equipment being used. An intriguing vantage point from which to evaluate engineering as a component of beauty culture can be found in laser hair removal research.

What is Laser Hair Removal?

Unwanted body hair can be reduced or removed without surgery by using lasers. One of India’s most well-liked minimally invasive cosmetic operations is laser hair removal, with more than one million procedures carried out annually. It may be a viable solution for people with excessive body hair searching for a practical technique to efficiently reduce or eliminate hair from both large and small parts of the body.

The science behind Laser Hair Removers:

In laser hair removal, the entire area from which a person wants to lose hair is exposed to laser light. Targeting areas with a specific range of melanin is how laser hair removal works. The hair follicle heats up more quickly than the surrounding skin because the laser generates a wavelength of light that should be largely absorbed by the hair and primarily reflected by the skin. Inflammation brought on by this kills the hair follicle, which generates hair.

Since the laser hair removal method relies on a difference in skin and hair color for the hair to absorb the light without burning the skin, no single laser can treat every type of skin and hair. Even if inactive, the melanin beneath the skin will absorb light at the same rate as the melanin found in hair instead of reflecting it. The laser won’t be able to “target” the hair if the skin and hair absorb light at the same rate. Due to this, laser hair removal was previously only an option for those with light complexion and black hair. However, new lasers have been developed that are effective for many skin and hair types.

Remember that the targeted hairs must be in a particular growth phase for laser hair removal to be effective. The optimal time to use lasers and comparable technologies is during the anagen or active growth stage. This is so that the laser light can effectively remove the hairs, which are melanin and keratin-rich at this time.

Side effects of Laser Hair Removal:

1. Redness:

Laser hair removal’s most frequent adverse effects are temporary pimples and redness that generally go away in 1-2 hours. These side effects are negligible and frequently resemble what you could experience even after waxing. Within hours of the surgery, the general irritability should go away. Ice packs can be used to assist in relieving edema. You should contact your doctor if you suffer symptoms that are more severe than mild discomfort or if the adverse effects do not go away or worsen over time.

2. Pimples/Folliculitis:

The hair is first shaved before the laser is applied during a laser procedure. Dead skin and hide from the first week following laser treatment shed off. These hairs have a prickly texture and can induce folliculitis, which looks like tiny pimple-like bumps and is brought on by skin irritation. With an antibiotic cream after laser treatment, that pimple typically go away. Get in touch with your doctor if it doesn’t.

3. Pigmentation:

Skin color changes are another negative effect of laser hair removal. Some people can observe slight color changes in the skin’s treated area. The treated region typically becomes lighter as the laser also targets the skin’s melanin. However, if you expose the skin to the sun after laser treatment without proper sun protection, pigmentation in the treated area is also possible. Over time these alterations usually disappear over time, and the skin returns to its normal state.

4. Burns:

Burns and blisters are a relatively uncommon side effect of laser hair removal. If laser hair removal is performed incorrectly, it frequently occurs. This is why it’s crucial to emphasize that this therapy should only be carried out under a dermatologist’s supervision. It is also found in those with darker skin tones when the skin’s melanin absorbs more vital laser energies, resulting in a blister. If a blister appears, it is crucial to avoid picking at it to prevent scarring.

Final Words

Laser-damaged hair follicles may take days or weeks to fall out entirely. The hair does not fall out right once, and occasionally, the shedding process resembles continuing hair growth. Results differ significantly between individuals, possibly caused by several variables such as hair thickness, density, or placement. Even though laser hair removal efficiently stops hair growth for months to years, it typically does not remove hair permanently. It does, however, provide a more long-lasting solution in comparison to shaving and waxing. Targeting the various stages of the hair development cycle requires several sessions, often 4–10, spaced 4-6 weeks apart. For longer-term outcomes, a few maintenance sessions per year may also be required after these sessions.
