Underarm hair can be a source of discomfort and embarrassment, specifically for those who prefer a clean, smooth complexion. While traditional hair removal methods like shaving or waxing can be effective in the short term, they often require frequent maintenance and may even cause skin irritation or ingrown hairs. 

Fortunately, laser hair removal has become a prevalent long-lasting solution for removing unwanted hair, including underarm hair. Laser hair removal can effectively reduce hair growth in the treated area by targeting hair follicles with a concentrated light beam. 

With this blog, we want to help you discover and explore the benefits of laser hair removal for underarm hair, and better understand the important considerations to keep in mind before undergoing the procedure.

Why do we have underarm hair?

Underarm hair, like other types of body hair, is thought to have evolved to regulate body temperature and protect against friction and chafing. However, the exact purpose and function of underarm hair needs to be better understood, considering that different individuals may have varied motivations.

One theory is that underarm hair helps trap sweat and other bodily fluids, which can cool the body. When sweat evaporates from the skin, it can help to lower body temperature, and the hair may help to hold the sweat in place, allowing it to evaporate more slowly.

It was also said that underarm hair might protect against friction and chafing, particularly for people who engage in activities that involve a lot of arm movement or who wear tight-fitting clothing. In addition, the hair may help to reduce friction between the skin and clothing or between the arms themselves, reducing the risk of irritation and discomfort.

Why do we remove underarm hair?

Hygiene is a reason why some people choose to remove underarm hair. Hair can trap sweat and bacteria, leading to unpleasant odours and irritation. Removing underarm hair can help reduce the number of microbes that accumulate in the area, improving hygiene and reducing odour.

Overall, whether or not to remove underarm hair is a personal choice that can depend on various factors, including personal preference, cultural norms, and hygiene concerns.

What is laser underarm hair removal?

Underarm laser hair removal is a cosmetic procedure that removes hair from the underarm area. The laser targets and damages the hair follicles, inhibiting hair growth. Laser hair removal is a safe and effective way to remove underarm hair. It is typically performed in a medical spa or dermatologist’s office and requires multiple sessions to achieve optimal results. The number of sessions needed can vary depending on the individual’s hair type, skin type, and the size of the treatment area.


During underarm laser hair removal, a handheld device delivers pulses of laser energy to the skin. The melanin absorbs the energy in the hair follicles, which causes them to heat up and become damaged. Over time, the damaged follicles cannot produce new hair, leading to permanent hair reduction. Here’s what happens during an underarm hair laser removal.

1. Consultation

Before the procedure, you will talk with a qualified professional to discuss your medical history, skin type, and the details of the process. They may also perform a patch test to determine how your skin reacts to the laser.

2. Preparation

You will be asked to shave the underarm area and avoid using any lotions, deodorants, or other products that may interfere with the laser. They will also apply a cooling gel to the skin to protect it from the laser’s heat.

3. Laser treatment

During the procedure, the doctor will use a handheld laser device to deliver pulses of laser energy to the underarm area. The melanin absorbs the energy in the hair follicles, which causes them to heat up and become damaged. As a result, the treatment may cause mild discomfort or a sensation of heat or stinging, but this can be minimised by using cooling techniques or numbing creams.

4. Aftercare

After the procedure, the doctor will provide instructions for aftercare. This may include avoiding sun exposure, wearing loose clothing, and avoiding hot showers or baths for a few days. You may also be advised to use a mild moisturiser or anti-inflammatory cream to soothe the skin.

Benefits of laser underarm hair removal

Underarm laser hair removal has many benefits. First, it is long-lasting compared to other hair removal options such as shaving, threading or waxing. A series of treatments can reduce hair growth, making you feel more confident to show off your underarms. 

Laser hair removal targets hair follicles without damaging the surrounding skin, making it a precise and effective way to remove hair from the underarm area. This can help reduce skin irritation and ingrown hairs with other methods, such as shaving or waxing.

Lastly, it is faster and more convenient. Underarm laser hair removal can be performed relatively quickly, with most sessions lasting 15-30 minutes. Meanwhile, it is more convenient since hair growth has been significantly reduced. Underarm laser hair removal can reduce the need for frequent maintenance, saving time and money in the long run.
