    Underarm laser hair removal: prices, sessions and results

    Armpits are one of the most popular areas for laser hair removal, for both men and women. No more daily shaving, no more irritation and no more deodorant that won’t stick: underarm laser hair removal offers a long-lasting solution for smooth, clear skin every day. At CtrlZ, it’s one of our flagship services. Here’s everything you need to know before getting started.

    Why use laser to remove underarm hair?

    Laser underarm hair removal offers many advantages over traditional methods:

    • No more need to shave every day or every other day
    • Odor reduction: less hair means less surface area for odor-causing bacteria
    • Improved perspiration: sweat evacuates more easily without a hair barrier
    • No more irritation: no more redness, pimples or itching from shaving
    • Goodbye ingrown hairs: underarm folliculitis disappears with laser treatment
    • Softer skin: no more “rough” effect a few hours after shaving

    💡 Did you know?

    Armpits are an ideal area for laser hair removal: hair is generally thick and dark, making it highly receptive to treatment. What’s more, the area is small, making sessions quick and results visible quickly.

    How does underarm laser hair removal work?

    Laser hair removal is based on the principle of selective photothermolysis. The laser beam targets the melanin in the hair. The light energy is converted into heat and destroys the hair bulb, without damaging the surrounding skin.

    The armpits are ideal for laser treatment:

    • Generally thick, pigmented hairs, highly reactive to lasers
    • Small area for fast sessions (5 to 10 minutes)
    • Skin rarely exposed to the sun, making treatment easier

    At CtrlZ, we use dual-wavelength lasers (Alexandrite 755 nm and Nd-Yag 1064 nm) adapted to all phototypes, from the lightest to the darkest skins.

    ⚙️ Pre-session preparation

    • Shave your armpits the day before or the morning of your appointment
    • Do not apply deodorant on the day of the session.
    • Avoid exposure to the sun in the preceding 4 weeks
    • No waxing or tweezing in the 4 weeks preceding the session

    How much does underarm laser hair removal cost?

    How many sessions for underarms?

    The number of sessions required for underarm laser hair removal is generally 6 to 8.

    This number is explained by the hair growth cycle: the laser is only effective on hair in its active growth phase (anagen phase). However, only 20% to 30% of hairs are in this phase at any given time. Several sessions, spaced out, are therefore needed to treat all follicles.

    The interval between sessions is 6 to 8 weeks for underarms, to allow dormant hair to enter the active phase.

    ⏱️ Your career in a nutshell

    • 6 to 8 sessions on average
    • 6 to 8 weeks between sessions
    • 5 to 10 minutes per session
    • Total treatment time: approximately 9 to 12 months

    What results to expect (before/after)

    Laser hair removal in the armpits can reduce hair growth by 80-95%. This is one of the areas where results are most spectacular, thanks to the nature of the hair (thick and dark).

    The results are gradually becoming apparent:

    • After 1 to 2 sessions: treated hair falls out within 5 to 15 days, and regrowth is already visibly reduced.
    • After 3 to 4 sessions: reduction of about 50%, hair grows back finer and lighter
    • After 6 to 8 sessions: virtually definitive result with very fine, sparse residual hair.

    CtrlZ transparency: we’re talking about long-term reduction, not “permanent” hair removal. A few fine hairs may grow back over the years, necessitating an occasional maintenance session.

    ✓ What our patients see

    No more daily shaving, permanently soft skin, less odour even at the end of the day, and the confidence to lift your arms without a thought. Armpits are often the area that convinces our patients to go on to other parts of the body.

    Is underarm laser hair removal painful?

    Armpits are a moderately sensitive area. The skin is thin and the area is rich in nerve endings.

    The sensations experienced vary from person to person, but are generally described as :

    • Tingling or “rubber band” tingling
    • A brief sensation of warmth with each pulse
    • Discomfort is quite bearable and short-lived (5 to 10 minutes).

    Our lasers are equipped with a pulsed cold air system that cools the skin continuously during treatment, significantly reducing discomfort.

    🧊 Comfort tips

    • Avoid coffee and other stimulants on the day of your session
    • Don’t shave too short: 1-2 mm is ideal
    • Anesthetic cream available on prescription if you are very sensitive
    • Subsequent sessions are often less sensitive as the hair becomes thinner.

    Underarm laser hair removal and perspiration

    It’s a common question: does laser hair removal affect perspiration?

    The answer is no. The laser only targets hair follicles and does not affect the sweat glands responsible for perspiration. You’ll continue to perspire normally.

    On the other hand, many patients report improved comfort after treatment:

    • Sweat evacuates more easily without the hair barrier
    • Odors are reduced because bacteria have less surface area to grow on
    • Deodorants work best on smooth skin
    • The feeling of freshness lasts longer

    💧 Perspiration and odors

    Laser hair removal does not reduce the amount of sweat produced, but it does improve comfort. Without hair, sweat evaporates faster and the bacteria responsible for unpleasant odors have less of a grip. The result: you feel fresher for longer.

    Risks and side effects

    The side effects of underarm laser hair removal are transient and not serious:

    • Redness lasting from a few hours to 24 hours
    • Slight swelling around follicles (perifollicular edema)
    • Sensation of heat similar to a mild sunburn

    Rarer risks (burns, pigment spots) are minimized at CtrlZ thanks to :

    • Systematic medical tele-expertise before any treatment
    • An initial laser test to assess your skin’s reaction
    • Settings adapted to your phototype
    • A 24/7 medical hotline

    🚿 Post-session care

    • No deodorant for 24 to 48 hours after the session
    • Soothing cream (such as Cicaplast or Cicalfate) if needed
    • Avoid intensive sports for 24 hours (perspiration = irritation)
    • No sauna or steam bath for 48 hours
    • Sun protection if exposed (rare for armpits)
