Laser vs Waxing: What’s Better for Underarms?
Youmna Rehman • August 11, 2025
When it comes to underarm hair removal, two of the most popular methods are laser hair removal and waxing. Both promise smooth, hair-free skin, but they work in completely different ways, with varying costs, pain levels, results, and maintenance. Choosing the right one depends on your pain tolerance, budget, lifestyle, and desired long-term results.
Let’s break it down in detail so you can decide which option works best for you.
How to Prepare for Your First Underarm Laser Session
How Each Method Works
Laser Hair Removal
Laser hair removal uses concentrated light to target the pigment (melanin) in your hair follicles. The heat from the laser damages the follicle, slowing down or permanently reducing future growth. Multiple sessions are needed, as hair grows in cycles.
Waxing
Waxing involves applying warm or cold wax to the skin and pulling it off quickly to remove hair from the root. It works instantly, but the results are temporary since the follicle remains intact and hair will grow back in a few weeks.
Pain Level
- Laser: Often described as a quick snapping or tingling sensation, similar to a rubber band snap. Many people find it less painful than waxing after the first few sessions, and numbing creams can help.
- Waxing: Usually more painful because hair is pulled out directly from the root along with a layer of skin cells. The pain can be sharp, especially in sensitive underarm skin, and is repeated every few weeks.
Cost Comparison
- Laser: Higher upfront cost (per session), but fewer sessions needed long-term. After the initial 6–8 sessions, you may only need yearly touch-ups.
- Waxing: Lower cost per session, but since you need it every 3–4 weeks, the expenses add up over time.
Example:
Laser may cost $150–$300 per session, but after a year, your hair growth can be reduced by up to 90%. Waxing may cost $20–$50 per session, but you’ll be paying for it indefinitely.
Time Commitment
- Laser: An underarm laser session typically takes 10–20 minutes, with 4–6 weeks between sessions.
- Waxing: The actual session takes 10–15 minutes, but you need to let hair grow out to at least ¼ inch before your next appointment, which means you can’t be hair-free all the time.
Longevity of Results
- Laser: Can offer permanent hair reduction after a complete treatment plan, with many people staying hair-free for months or years.
- Waxing: Results last around 3–4 weeks, and hair regrows at the same thickness.
Skin Sensitivity & Side Effects
- Laser: Temporary redness, mild swelling, or slight irritation for a few hours. Risk of pigmentation changes if aftercare isn’t followed.
- Waxing: Can cause redness, irritation, ingrown hairs, and in some cases, skin tearing—especially if the skin is not properly prepped.
Hair Type & Skin Tone Suitability
- Laser: Works best on dark hair with light skin, but newer laser technologies are effective for a wide range of skin tones. Not very effective on very light, red, or grey hair.
- Waxing: Works on any hair color and skin tone, making it universally accessible.
Hygiene & Ingrown Hair Risk
- Laser: Significantly reduces ingrown hairs over time because it destroys the follicle.
- Waxing: Can cause ingrown hairs if dead skin cells clog pores or if hair breaks under the skin instead of being pulled out cleanly.
What Not to Do Before and After Underarm Laser Hair Removal
Which One Should You Choose?
Choose Laser Hair Removal if you want:
- Long-term results
- Less maintenance over time
- Reduced ingrown hairs
- Willingness to invest more upfront
Choose Waxing if you want:
- A more affordable short-term option
- Instant smoothness without technology
- A method that works for all hair colors
Final Verdict
If your goal is permanent reduction and freedom from frequent appointments, laser hair removal is the clear winner for underarms. However, if you want a quick fix for a special occasion or aren’t ready for a bigger financial commitment, waxing is a tried-and-true method that works instantly.

What Not to Do Before and After Underarm Laser Hair Removal Why Laser Hair Removal for Underarms Is So Popular The underarms are one of the most commonly treated areas for laser hair removal, and it’s easy to see why. The area is small, which means treatments are quick. Plus, the hair tends to be darker and coarser, making it more responsive to the laser. For many people, a few sessions can mean smoother skin and a serious reduction in regrowth. How Long Does the Actual Laser Session Take? Most underarm laser sessions take about 10 to 15 minutes . That’s it. This includes the time it takes for the technician to prepare the skin, adjust the laser settings, and apply the treatment to both underarms. If you’ve shaved properly beforehand (which is usually recommended), the session will go even faster. Here’s a breakdown of what usually happens during that time: Quick skin check by the technician Wiping the area clean if needed Application of the laser pulses (this usually takes just 5-7 minutes for both underarms) Optional application of soothing gel or aloe afterward You’ll be in and out in less time than it takes to scroll Instagram. Factors That Can Affect Session Duration While 10–15 minutes is the average, a few things can make your session take slightly longer or shorter. Skin and Hair Type : Coarser or denser hair might require more laser passes. Pain Tolerance : If you’re sensitive to the laser sensation, you might need breaks. Technician Technique : Some clinics use faster machines or more experienced technicians, which can speed things up. Pre-Treatment Preparation : If you forgot to shave or have residual deodorant on your skin, the technician may need to clean or prep the area, adding a few minutes. What About the First Appointment? Your first laser hair removal appointme nt will likely be a bit longer — around 20 to 30 minutes total. That’s because the technician will go over your medical history, explain the procedure, perform a patch test, and answer any questions you may have. But once you get into the routine of regular sessions, the actual laser part rema ins quick. Does Underarm Laser Hair Removal Really Work? How Many Sessions Will You Need? Most people need 6 to 8 sessions for optimal results, spaced about 4 to 6 weeks apart. Some people see a significant reduction in hair growth after just a few sessions, but consistency is key. The speed of the sessions makes it easier to stick to your treatment plan. Can You Schedule During a Lunch Break? Yes, and that’s one of the best things about underarm laser hair removal . Since the session is so short, it’s ideal for squeezing in between classes, errands, or during a break from work. There's no downtime required, so you can go back to your day immediately. Aftercare: Does That Add Time? After your session, you might experience mild redness or a warm sensation on your skin. Applying aloe vera or a soothing lotion is usually enough. The aftercare process is simple and doesn’t take much time, but avoid applying deodorant or taking hot showers for at least 24 hours. Laser vs. Other Hair Removal Methods (Time Comparison) If you’re used to shaving every few days or waxing every few weeks, laser hair removal is a major time-saver in the long run. Here’s how it compares: Shaving : Takes 3–5 minutes per session, multiple times a week Waxing : Takes about 30 minutes every 2–4 weeks Laser : 10–15 minutes every 4–6 weeks, and long-term results after 6–8 sessions Final Thoughts Laser hair removal for underarms is one of the quickest cosmetic treatments available.
