First-time underarm waxing: prep, pain, and what to expect

5 min read·November 6, 2025·By the GetMarkd team

So, you're thinking about ditching the razor and trying underarm waxing? That's a great choice for smooth, long-lasting results. Many of us start with shaving our underarms, but once you experience the freedom of not having to think about stubble for weeks, you might never go back. If you're a little nervous about your first time, don't worry! It's completely normal, and we're here to walk you through everything you need to know.

Getting a first time underarm wax is a simple process, but some good preparation can make a big difference in your experience. We'll cover how to get ready, what it actually feels like, and how to keep those underarms looking and feeling fantastic afterward.

Prepping Your Underarms for Wax Day

Preparation is key for a successful first time underarm wax. First, make sure your hair is the right length. It should be about ¼ inch long, or roughly the length of a grain of rice. This usually means letting it grow out for 2-3 weeks after your last shave. If it's too short, the wax won't grab it effectively; if it's too long, it can be more uncomfortable.

The day before your appointment, gently exfoliate your underarms. You can use a mild scrub or even just a washcloth to slough off dead skin cells. This helps prevent ingrown hairs and allows for a cleaner wax. On the day of, clean your skin with soap and water to remove any deodorant, oils, or lotions. Come to your appointment fresh and clean, but skip the antiperspirant.

What to Expect: The Waxing Process Step-by-Step

Once you're in the salon, your esthetician will have you lie down or sit in a comfortable position that allows easy access to your underarms. They'll cleanse the area again with a pre-wax solution to ensure it's free of any residue and to prepare the skin. Sometimes a bit of powder might be applied to protect the skin and help the wax adhere better to the hair.

Next, the esthetician will apply warm wax in small sections, moving quickly. They'll press a strip over the wax (if using soft wax), or let the wax cool and harden slightly (if using hard wax), and then pull it off swiftly against the direction of hair growth. This happens incredibly fast! They'll repeat this a few times until all the hair is removed. It's usually a quick process, often taking only 5-10 minutes in total for both underarms.

After waxing, any leftover wax residue will be removed, and a soothing oil or lotion will be applied to calm your skin and reduce redness. Your esthetician might also press a cool compress on the area to help with any initial tenderness.

Addressing the 'Ouch Factor' – Pain Expectations

Let's be real: waxing isn't pain-free, especially for a first time underarm wax. However, the pain is very quick and temporary. It's often described as a sharp sting or a rubber band snap. The first pull is usually the most intense, and it gets a little easier with each subsequent pull as your skin gets used to the sensation.

Many clients find underarm waxing less painful than other areas like the bikini line, as the area is smaller and the hair isn't quite as coarse. Your pain tolerance is unique, but it’s over in seconds. Taking an over-the-counter pain reliever like ibuprofen 30-45 minutes before your appointment can help dull the sensation. Avoid caffeine or alcohol before waxing, as they can make your skin more sensitive.

Aftercare for Smooth, Happy Underarms

The first 24-48 hours after your wax are crucial for proper aftercare. Avoid hot showers, baths, swimming pools, saunas, and intense exercise that causes excessive sweating. These activities can irritate freshly waxed skin and lead to breakouts. Wear loose-fitting clothing to prevent friction and allow your skin to breathe.

To prevent ingrown hairs, start exfoliating a few days after your wax, once the redness has subsided. Use a gentle exfoliating mitt or a salicylic-acid serum a few times a week. Keeping your skin hydrated with a light, non-comedogenic moisturizer will also help maintain softness and prevent dryness. Avoid antiperspirants with harsh chemicals for the first day or two; opt for a natural deodorant or skip it entirely if you can.

Long-Term Benefits and What to Expect Between Waxes

After your first time underarm wax, you can enjoy smooth skin for about 2-4 weeks. When the hair starts to grow back, it will typically be finer, softer, and sparser than what you're used to when shaving. Regular waxing (every 3-4 weeks) can actually lead to permanent hair reduction over time, as it damages the hair follicle.

Consistent waxing also means less irritation, fewer ingrown hairs if you follow proper aftercare, and freedom from daily shaving. Your underarms might even appear brighter and smoother overall. It's a game-changer for many, offering a low-maintenance solution for hair removal.

FAQ

How long should my underarm hair be for a first time underarm wax?

For your first underarm wax, your hair should be about ¼ inch long, or roughly the size of a grain of rice. This usually means letting it grow for 2-3 weeks after your last shave, ensuring the wax can properly grip the hair for effective removal.

Does underarm waxing really hurt a lot?

Underarm waxing involves a quick, sharp sting, often compared to flicking a rubber band. While not pain-free, it's very brief and the area is small. Many find it less painful than other body parts, and the discomfort lessens with regular waxing.

What should I avoid after my first underarm wax?

For the first 24-48 hours after waxing, avoid hot showers, baths, swimming, saunas, and intense exercise. Also, skip harsh antiperspirants, tight clothing, and direct sun exposure to prevent irritation and allow your skin to heal properly.

How often do I need to wax my underarms after the first time?

After your first time underarm wax, you can typically go 3-4 weeks between appointments. Regular waxing encourages finer hair growth and can lead to longer-lasting smoothness. Your esthetician can recommend the best schedule for your hair growth cycle.

Can I use deodorant right after underarm waxing?

It's best to avoid antiperspirants with harsh chemicals for at least 24-48 hours after your wax, as they can irritate freshly waxed skin. Opt for a natural deodorant, or skip it entirely if you can, allowing your pores to breathe and heal.
