Underarm Hair Removal: 5 Methods Compared and the Best Choice

Removing underarm hair is very common today, and the underarms are the area most people care about. Overgrown underarm hair can hurt your appearance and even make some people shy about wearing sleeveless tops or tank tops. So what are the ways to remove underarm hair, and are you using the right one? This article introduces 5 common underarm hair removal methods with their pros and cons, and recommends the aesthetic medicine treatment that is the most effective without harming the skin.

Why Remove Underarm Hair? 3 Benefits at a Glance

1. Appearance

A thick tuft of underarm hair affects the first impression people get of your appearance and can easily come across as untidy or unclean. Some people even associate body odor and unpleasant smells with underarm hair. In contrast, after underarm hair removal you get smooth, clean underarms and feel more confident and look better with every movement.

2. Prevent sweat from sticking and causing odor

The underarms have a very dense distribution of sweat glands. If the underarm hair is too thick, sweat easily clings to and builds up in the hair, making it hard to wipe off. Over time, bacteria multiply and odor can even develop, so many people choose underarm hair removal to reduce sweat sticking and body odor.

3. Keep the area ventilated and dry

The underarms have many skin folds, so friction and trapped bacteria and dirt are common, and when covered by clothing the area lacks airflow and can develop odor. With underarm hair removal, you can not only clean the underarm folds more easily and keep them hygienic, but also reduce the stuffy feeling and keep the underarms fresh and well ventilated.

5 Common Underarm Hair Removal Methods

1. Razor

Razor blades are usually made of stainless steel or other metal, and their sharp edge cuts hair off at the surface of the skin. The process is extremely simple, convenient, and fast, but one slip can easily cause bleeding or scarring. In addition, after shaving, the underarms only have the hair cut at the surface, while the hair follicles are actually left intact, and dark stubble starts showing up after a while. The effect is therefore short-lived, and you need to shave again, which can actually make hair look thicker and grow faster the more you shave, so using a razor for underarm hair removal is not recommended.

2. Depilatory cream

Depilatory creams usually contain chemicals such as potassium sulfide or sodium sulfide, which dissolve the protein in hair, making it weak and easy to wipe away. However, the dissolving process can irritate the skin, causing side effects such as allergic reactions and a thickened stratum corneum; in addition, depilatory cream cannot remove hair from the root, so the results usually last only a few days before the hair grows back.

3. Tweezing

Some people are used to using tweezers to remove underarm hair. Although this pulls the hair out from the root, it is not only very painful, but also easily irritates the surrounding skin, leading to follicle inflammation, hyperpigmentation, and allergic redness and swelling and other problems.

4. Hot wax

Melted wax is used to pull hair out at the root. Once the wax is applied to the skin and cools, its stickiness makes it adhere to the hair and skin. When the wax is quickly ripped off, it takes the attached hair with it, so it can remove hair more cleanly and last longer, with results lasting about 1 month, and with long-term use, follicles shrink and hair becomes finer.

However, this method is very painful, and may cause discomfort on sensitive skin. The technician's skill also matters a great deal, and the wax temperature must be controlled, otherwise the underarm skin may be burned or damaged.

5. Laser hair removal

Hair follicles contain melanin, so with laser underarm hair removal, specific nanometer wavelengths deliver energy deep into the follicle and the melanin absorbs the laser light, which further carbonizes the growth structure of the follicle and slows hair growth. With underarm laser hair removal, as long as sessions are timed to the hair growth cycle and repeated regularly over a few treatments, a semi-permanent hair removal result can be achieved.

What Is Triton Hair Removal?

TRITON hair removal laser combines two popular lasers on the market, the 755nm Alexandrite laser and the 810nm diode laser, and is cleared by the US FDA and approved by Taiwan FDA. It uses a unique high-power, multi-wavelength hair removal system that provides safe and effective treatment even for fine hair, light-colored hair, and wheat-toned skin, which are harder to treat. Thanks to the advantages of multi-wavelength laser, it can also treat hair in a wider range of growth phases and remove new follicles and deep follicles together, so noticeable results can be seen with fewer hair removal sessions.

The 3 Phases of the Hair Growth Cycle:

Hair grows and is replaced in cycles, in three phases: the growth phase (anagen), the regression phase (catagen), and the resting phase (telogen). Each follicle cycles independently, and when the process ends, it re-enters the next growth phase.

1. Growth phase (anagen)

About 80%-90% of the hair on the body is in the growth phase, when the follicle and hair shaft are both intact. The hair contains a large amount of melanin and absorbs laser light very well, making this the best time for hair removal.

2. Regression phase (catagen)

Next, hair enters a regression phase lasting 2-5 weeks. Nutrient delivery beneath the skin decreases, melanin is no longer produced, follicle cells begin to die off, and hair growth pauses. Although there is less melanin at this point, Triton hair removal, with its combined wavelengths, can still treat hair in this phase.

3. Resting phase (telogen)

The follicle gradually shrinks due to insufficient nutrients, and the hair enters a shedding state. There is almost no melanin around the stem cells, so no laser light can be absorbed at this stage and treatment is ineffective.

3 Key Features of Triton Hair Removal

1. Nearly painless

Triton hair removal features 3P cooling technology, which cools the skin before, during, and after each laser pulse. Combined with a gel and a gliding technique, it allows the skin to stay at a normal temperature before, during, and after treatment for a nearly painless experience, making it the most comfortable laser hair removal treatment!

- Patented 3P cooling technology:

Triple cooling technology, with a Pre-Cooling Plate, Parallel Cooling at the sapphire tip, and a Post-Cooling Plate, effectively reduces the stinging sensation during laser treatment and the thermal effect afterward, so you don't have to endure the procedure. It lowers treatment pain and makes the procedure safer and more comfortable.

STEP 1: The pre-cooling plate cools the skin for the first time

STEP 2: As the laser fires, the sapphire tip cools the skin at the same time

STEP 3: After the laser fires, the post-cooling plate cools the skin a third time

2. High hair removal efficiency

Traditional hair removal lasers use a single wavelength, so the laser energy only acts on hair in the growth phase. Triton hair removal uses a laser with combined wavelengths, which can deliver energy to follicle cells deeper down as well as to growth-phase hair, removing new follicles and deep-seated hair together, and one Triton session is equal to one session at the 755 wavelength plus one at the 810 wavelength, so fewer sessions are needed and hair removal is more efficient.

3. Suitable for all hair types and skin tones

The Triton hair removal laser can deliver two different wavelengths of energy at the same time. The 755nm wavelength is better absorbed by melanin, while the 810nm wavelength reaches follicle cells deeper in the skin and addresses hair in different growth phases. Compared with traditional laser hair removal, the combined wavelengths have the advantage of being able to handle more hair concerns and suit all skin tones and hair types, which makes treatment planning more flexible.
