Sugaring Underarms: 2026 Prep Myths Debunked

I see a lot of people frustrated with their underarm sugaring results, and honestly, it’s because of all the bad advice out there about prep and aftercare. They expect a perfectly smooth finish but end up with irritation and stubble because they’ve been told things like “just show up” or “you can put deodorant on right after,” which is just completely wrong.

Myth 1: You don’t need to do anything special before sugaring your underarms.

This idea that you can just walk in for an underarm sugaring with zero prep is what leads to most bad experiences. The underarms are a tricky spot, they’re concave, sensitive, and prone to moisture, so what you do beforehand really matters. If you don’t prep, you’re looking at a painful session with patchy results, where I have to go over the same spot multiple times, leading to angry, red skin. A client might come in with really dry, flaky skin, for example, and the sugar paste will just stick to the skin itself instead of grabbing the hair, making the whole process hurt more and work less. The bottom line is, exfoliation is non-negotiable. I tell every client to gently exfoliate their underarms 24 to 48 hours before they come in. This gets rid of the dead skin buildup that can clog the surface, allowing the sugar paste to get a clean grip on the hair. You can use a soft brush, a gentle scrub, or a chemical exfoliant with something like salicylic acid, but don’t go crazy with it, harsh scrubbing will just make your skin raw. A 2024 review in the Journal of Clinical and Aesthetic Dermatology confirmed that pre-exfoliation seriously cuts down on ingrown hairs after hair removal, even in the axilla (underarm) area. Hair length is also a deal-breaker. If it’s too short, the paste has nothing to hold onto. You need at least 1/4 inch of growth, which is about 10 to 14 days after shaving. On the flip side, if your hair is super long (over half an inch), it can make the pull more painful, so trimming it down a little is a good idea.

Myth 2: Any deodorant is fine to use before your sugaring appointment.

Showing up to your appointment with deodorant on is a recipe for failure. So many people do it without thinking, but antiperspirants and deodorants create a barrier on the skin that makes sugaring nearly impossible. Antiperspirants plug sweat glands with aluminum compounds, and deodorants often leave behind a film of oils and fragrances. Because sugar paste is water-soluble, it can’t stick to a surface that’s coated in these residues. This means clean, dry skin is paramount. Any slickness from deodorant prevents the paste from properly wrapping around the hair shaft, turning what should be a quick session into a frustrating one where we have to re-apply paste over and over, irritating your skin. This is about getting a clean result efficiently and protecting your skin from unnecessary trauma. Before any session starts, the area has to be cleansed with a gentle, non-comedogenic soap and water and then dried completely. I always use a pre-sugaring powder (usually just cornstarch or arrowroot) to absorb every last bit of moisture, which gives the sugar paste the perfect dry surface it needs to grip only the hair.

Myth 3: You should immediately apply antiperspirant or deodorant after sugaring.

I know it’s a habit, but you have to avoid putting on your normal deodorant right after your appointment. This is probably the most common mistake I see. After sugaring, your hair follicles are wide open and the skin’s protective barrier is down, making it very susceptible to irritation. Slapping on products with aluminum, alcohol, or synthetic fragrances at this point is asking for trouble, you’re basically inviting red bumps, painful ingrowns, or even folliculitis, which is an infection of the hair follicle. The point is, your skin needs to breathe and heal. For the first 24 to 48 hours, just leave it alone. No antiperspirants, no scented deodorants. If you’re really concerned, a light dusting of cornstarch or a very gentle, aluminum-free natural deodorant might be okay, but even that should be used sparingly. Your focus should be on calming the skin, not covering it up. The American Academy of Dermatology Association backs this up, advising people to avoid harsh chemicals on any freshly treated skin to let it heal properly. Giving your skin this recovery window is what prevents angry reactions and lets the follicles close up peacefully.

Myth 4: Hot showers and intense workouts are fine right after sugaring.

People often think they can leave a sugaring appointment and go straight to their hot yoga class or hit the sauna, but that’s a huge mistake. Your underarms are a unique area that’s all about friction and sweat, and exposing freshly sugared skin to that combination is a perfect storm for irritation. I’ve had so many clients call me with breakouts or intense redness because they went to the gym or took a scalding hot shower right after their session. Why does it matter? Because your skin needs a cool-down period. For the next 24 to 48 hours, you have to avoid anything that introduces excessive heat or sweat. That means no hot showers, saunas, steam rooms, or tough workouts. Heat opens your pores even more, and sweat introduces bacteria directly into those open follicles, which can easily lead to folliculitis. The National Eczema Association gives similar advice for compromised skin: stay away from hot water and sweat to avoid flare-ups. Stick to lukewarm showers and don’t scrub the area. Also, wear loose cotton tops to minimize friction and let your skin breathe. This isn’t about being overly cautious. It’s the basic requirement to prevent irritation.

Myth 5: You don’t need to moisturize sugared skin.

The idea that you don’t need to moisturize after sugaring is totally wrong and will just sabotage your results. People think the exfoliation from the sugar is enough, but that’s not how it works, especially for underarms which most people ignore other than swiping on deodorant. When you skip hydration, your skin gets dry and flaky. That dry surface then traps the new, softer hairs trying to grow back, causing more ingrown hairs. The fact is, consistent moisturizing is key to healthy, smooth skin. After a session, your skin is sensitive and needs moisture to repair its barrier and stay flexible. I tell my clients to start applying a gentle, alcohol-free moisturizer or serum twice a day, but wait 24 hours after the appointment to begin. Ingredients like aloe vera, hyaluronic acid, or shea butter are great for calming and hydrating. Just stick to a light, water-based lotion for the first few days to avoid clogging those open pores. Keeping the skin supple makes it much easier for the hair to grow through properly, and it also makes your next sugaring appointment go smoother because the hair releases more easily. Getting smooth results from underarm sugaring is totally achievable, but it depends entirely on doing the right prep and aftercare. Understanding these points will make your experience less painful and your results last longer.
