Quick answer: Most people need about 6 to 8 underarm laser hair removal sessions, spaced roughly 4 to 8 weeks apart, to get long-lasting hair reduction. The treatment feels like a quick snap or warm pinch, takes only a few minutes per visit, and often reduces ingrown hairs and razor bumps as the hair gets finer. You can choose per-session pricing or a package. Oxygen Med Spa in Orland Park offers laser hair removal with a personal consultation and treatment plan.
Personalized treatment plans · Quick, comfortable sessions · Per-session and package options · Clear guidance on prep and aftercare
If you are tired of shaving every other day and dealing with stubble, razor burn or ingrown hairs, underarm laser hair removal is one of the most popular ways to get long-lasting smoothness. The underarm is a small, quick area to treat, and many people notice a clear difference within the first few sessions.
This guide explains how many sessions the underarms usually need, how the treatment feels, what to expect with darkening and ingrown hairs, how to prepare and care for your skin, and how pricing typically works. You can also read about our full laser hair removal services at Oxygen Med Spa.

How Underarm Laser Hair Removal Works
Laser hair removal uses concentrated light that is absorbed by the pigment in the hair. The energy travels down to the follicle and reduces its ability to grow new hair. Because hair grows in cycles, and hairs respond best when they are in the active growth phase, treatment is done as a series of sessions rather than just once.
How Many Sessions Do Underarms Need?
The number of sessions depends on your hair colour and thickness, skin tone, hormones and how your hair responds. The table below shows what many people experience.
| Stage | What you may notice |
|---|---|
| Sessions 1 to 2 | Hair grows back thinner and more slowly |
| Sessions 3 to 4 | Visible reduction, fewer regrowth days and less stubble |
| Sessions 5 to 8 | Most treated hair is gone, with only fine or sparse regrowth |
| After your series | Long-lasting smoothness, with an occasional touch-up if needed |
Does Underarm Laser Hair Removal Hurt?
Most people describe the feeling as a quick snap or a warm pinch. Underarm skin can feel a little more sensitive than the legs because it is thin and the hair is dense, but each session is very short, so the discomfort passes quickly. Treatment often feels easier over time because there is less hair left to treat in later sessions.
- Avoid booking right before your period if your skin feels more sensitive then.
- Tell your provider if the treatment feels too strong so the settings can be adjusted.
- Arrive with clean, dry skin and no products on the area.
Darkening and Ingrown Hairs Under the Arms
Many people look into laser because of ingrown hairs, razor bumps and underarm darkening caused by years of shaving, waxing and friction.
| Concern | What to know |
|---|---|
| Ingrown hairs | As hair becomes finer and sparser, fewer hairs curl back into the skin, so ingrowns often reduce over the course of treatment |
| Razor bumps | Less shaving means less irritation, which can calm the area |
| Underarm darkening | Some darkness comes from repeated shaving or waxing irritation, and reducing that irritation may help the area look more even. Laser hair removal is not a dedicated pigmentation treatment |
| Temporary redness | Mild redness or small bumps around the follicles after a session are common and usually settle within a day or two |
How to Prepare for Your Appointment
- Shave the area the day before or the morning of your session. Do not wax, tweeze or thread, because the hair root needs to be present for the laser to work.
- Avoid sun exposure and tanning on the area for several weeks before treatment.
- Skip deodorant, creams and perfume on the day of your appointment.
- Tell your provider about any medications, recent sun exposure, skin conditions or products you use on the area.
Aftercare: What to Do After Treatment
- Use a gentle, fragrance-free moisturiser or soothing gel if the skin feels warm or tight.
- Avoid hot showers, saunas, intense workouts and heavy sweating for the first day or two.
- Wear loose, breathable clothing to reduce friction.
- Hold off on harsh deodorants and exfoliants until the skin feels normal, and ask your provider which products are safe to use.
- Keep the area out of direct sun and use sunscreen if it will be exposed.
- Do not pluck or wax between sessions. Shaving is fine if needed.
Results Timeline
| When | What to expect |
|---|---|
| First 1 to 2 weeks | Treated hairs shed gradually |

Laser vs Shaving Underarms
| Factor | Shaving | Laser hair removal |
|---|---|---|
| How long results last | A day or two | Long-lasting reduction |
| Ingrown hairs and razor bumps | Common | Often reduced over time |
| Time spent | Ongoing, several times a week | A few quick sessions, then little upkeep |
| Upfront cost | Low | Higher, but you stop buying razors and products |
Cost: Per Session vs Package
Underarms are one of the smaller and more affordable areas to treat. You can usually choose between paying per session or buying a package. A package typically lowers the cost per visit and helps you finish the full series, which is what gives the best results.
| Option | Best for |
|---|---|
| Single session | Trying treatment first or topping up after your series |
| Package of sessions | Completing a full course at a lower cost per visit |
| Combined areas | Treating underarms with other areas for added savings |

Who Is a Good Candidate?
Laser hair removal works for many skin tones and hair types when the right technology and settings are used. Very light, grey or white hair responds less well, and recent tanning or certain medications can affect whether treatment is safe. A consultation will confirm whether underarm laser is right for you.
Before You Book: A Quick Checklist
- Avoid sun exposure and tanning on the area.
- Shave the area before your appointment, and do not wax or tweeze.
- Arrive without deodorant, lotion or perfume on the skin.
- List any medications or skin conditions to share with your provider.
- Decide whether you prefer single sessions or a package.

Underarm Laser Hair Removal FAQs
Is underarm laser hair removal permanent?
Laser hair removal gives long-lasting hair reduction rather than a guarantee of permanent removal. Many people enjoy smooth skin for years, and some choose occasional maintenance sessions.
How many sessions do underarms need?
Many people need around 6 to 8 sessions, spaced about 4 to 8 weeks apart. Your provider will give you a personal estimate at your consultation.
Does underarm laser hair removal hurt?
Most people feel a quick snap or warm pinch. Sessions are very short, and treatment often feels easier over time as the hair thins.
How long does an underarm session take?
Underarms are quick to treat, and many sessions take just a few minutes, plus time for your skin check and preparation.
Can I shave between sessions?
Yes. Shaving is fine between sessions. Avoid waxing, plucking and threading, because they remove the hair root that the laser needs to target.
Will laser help with ingrown hairs?
Often yes. As hair becomes finer and sparser, fewer hairs get trapped under the skin, so ingrowns and razor bumps commonly reduce over time.
Will laser lighten dark underarms?
Laser hair removal is not a pigmentation treatment, but less shaving and waxing irritation may help the area look more even. Ask your provider about other options if darkness is your main concern.
Is it safe to get underarm laser in the winter?
Yes. Fall and winter are popular times to start because there is usually less sun exposure, and you can finish your series before summer.
Is it cheaper to buy a package?
Packages usually lower the cost per session and help you complete the full series. Contact our team for current pricing and offers.
