Unwanted hair growth can be frustrating and time-consuming. Over the years, many attempts have been made to tackle this problem, from shaving to waxing. Both methods have challenges; shaving is less long-lasting, and waxing can be painful. Fortunately, another method is growing in popularity: laser hair removal. This technique has been performed for decades and is a popular approach. But how does it work, and is it permanent? Let’s take a look.
The science behind laser hair removal
This is a technique by which light energy is used to destroy hair follicles. The treatment targets the pigment in the hair and sends pulses of light into the hair shaft, which then absorbs the energy and heats up. As the hair heats up, it damages the follicle, making it unable to produce any more hair growth. Since darker hair contains more pigment, it tends to be more receptive to the laser treatment.
The process of laser hair removal
The technician will shave the treated area before a patient undergoes the laser hair removal procedure. This ensures that the laser focuses solely on the hair follicles, not the hair itself. This best avoids folliculitis. Once the area is shaved, the patient will wear protective goggles to shield their eyes from the laser light. The technician will then apply a cooling gel to the treatment area, which helps to soothe the skin and minimize any potential side effects. Finally, the laser is set to a specific wavelength, and the technician pulses it over the treatment area.

Is laser hair removal permanent?
Laser removal is often advertised as a permanent method; it is more accurate to say that it drastically reduces hair growth. It is not guaranteed that all hair will be permanently removed, but most will. However, achieving the desired results may take several sessions, and some maintenance may be required. It’s also essential to note that the success of the treatment can depend on a few factors, such as the patient’s skin type, hair type, and color.
Potential side effects
Like any cosmetic procedure, laser hair removal has potential side effects. Some of the most common side effects include redness, itching, and swelling, which usually subside within a few hours of the treatment. In some cases, patients may experience temporary hyperpigmentation, which causes dark patches of skin to appear where the treatment was performed. However, this is usually only temporary.
Aftercare
After a session, it’s essential to properly care for the treated area. Avoid any activities that may cause friction, such as tight-fitting clothing, and refrain from using skincare products containing acids or retinoids. It’s also crucial to avoid exposing the treated area to the sun, as the skin may be more sensitive to UV rays after a laser treatment.
Final thoughts
Laser hair removal is a popular cosmetic procedure that reduces unwanted hair growth. Its results can last a long time and are mostly pain-free, making it a more effective and preferred alternative to traditional methods.
