How Underarm Laser Hair Removal Works
Underarm laser treatment uses focused light energy to target hair follicles under your skin and stop them from producing new hair.
The process takes advantage of how hair grows in different stages to achieve permanent hair reduction over multiple sessions.
The Procedure of Underarm Laser Hair Removal
The underarm laser hair removal session will be quick and straightforward.
When you arrive, your provider will clean your underarms and check that the area is freshly shaved.
Darker hair absorbs more light energy, which is why laser technology works best on darker hair against lighter skin.
However, newer machines can treat a wider range of skin tones safely.
During the actual treatment, you’ll feel quick warm sensations as the laser passes over your skin.
Some laser systems include cooling features that protect your skin and reduce discomfort.
Most appointments take only 10 to 15 minutes from start to finish.
When Should I Go Underarm Hair Removal?
Hair grows in three stages, and laser hair removal for underarms only works on hair in the active growth phase. This is why you need shaving before treatment.
The anagen phase is when hair actively grows and stays connected to blood supply.
The catagen phase is a short transition period when hair stops growing.
The telogen phase is the resting stage before hair falls out.
Only hair in anagen can be effectively treated because the follicle is most vulnerable during active growth.
At any given time, only 20 to 30 percent of your underarm hair is in the growth phase. This means each laser hair removal treatment catches a different portion of follicles.
Benefits of Underarm Laser Hair Removal
Smoother Skin and Confidence Boost
Your underarms become noticeably smoother after laser treatments.
Many people notice their skin texture improves after a few sessions.
You can wear sleeveless tops, tank tops, and swimwear without worrying about visible hair or skin bumps.
Preventing Ingrown Hairs
Ingrown hairs are a common problem with shaving and waxing. They happen when hair grows back into the skin instead of outward.
This causes painful red bumps, inflammation, and sometimes infection.
This benefit is especially helpful if you have coarse or curly underarm hair that’s more prone to growing inward.
Long-Term Results
After completing a full series of sessions, most people see 80 to 90 percent permanent hair removal in the treated area.
Cost-Effectiveness Over Time
Laser hair removal requires an initial investment but provides benefits of laser hair removal that last for years. After your treatment series is complete, you’ll rarely need to buy hair removal products again.
The time you save is valuable too—no more daily shaving routines or monthly waxing appointments.
Do You Really Need to Get Underarm Hair Removed?
It is a completely personal decision. There is no medical reason to remove underarm hair, nor is there any harm in leaving it.
Why Some People Choose to Remove It?
- Body Odor: Removing the hair helps to reduce body odor, and deodorants can be applied more directly and evenly to the skin when there is no hair.
- Aesthetics: Many people prefer the look and feel of smooth, hairless underarms.
- Comfort: For some, especially athletes, underarm hair can cause friction or feel uncomfortable during physical activity.
Why Some People Choose to Keep It?
- It’s Natural: Hair is a natural part of the human body, and there is no inherent need to remove it.
- Pheromones: Some theories suggest that underarm hair helps to trap natural scents called pheromones, which may play a subtle role in attraction.
People Who Shouldn’t Get Underarm Laser Hair Removal
If you’re pregnant, you should wait until after delivery since there isn’t enough research on how lasers affect pregnancy.
Tanned or sunburned skin increases your risk of complications like hyperpigmentation or burns. Your medical history matters too, so discuss any health conditions or medications with your technician during consultation.
