Waxing Pain: Genetics & Hormones in 2026

A lot of people, 1 in 10, in fact, deal with chronic pain, which just goes to show how differently we’re all wired for discomfort. When we talk about waxing, the huge difference in a person’s pain threshold is usually chalked up to psychology or just what people say. But the science is pointing somewhere else: our genetics and hormones are major players in how bad that pull of the wax strip feels. Figuring out these biological details gives us a much smarter way to handle waxing pain.

The SCN9A Gene and Pain Sensitivity

There’s a specific gene, the SCN9A gene, that basically acts as your body’s pain volume dial. A study in Nature Communications found that a particular variant of this gene is linked to much higher pain sensitivity. The gene itself builds a voltage-gated sodium channel (Nav1.7) which is a primary pathway for pain signals in your neurons. According to the NCBI, variations here can cause everything from complete insensitivity to pain to extreme, constant pain. The specific detail that matters for us is that people with the rs6746030 variant consistently report lower pain thresholds to stimuli like pressure and heat. My take on this is simple: if you have this genetic makeup, waxing will feel more intense for you. It’s about your nervous system’s built-in response. What one person calls a minor sting, you might genuinely feel as sharp pain because of your DNA. This moves the discussion away from subjective toughness and toward an objective biological reality.

Estrogen and Progesterone: Hormonal Impact on Pain

The monthly cycle of estrogen and progesterone has a massive effect on pain that most people (and even some practitioners) don’t consider. Research from the University of Michigan‘s School of Nursing consistently finds that pain sensitivity changes dramatically throughout the menstrual cycle. Specifically, pain tends to spike during the late luteal phase and early follicular phase, the days right before and during your period. In this window, estrogen levels plummet while progesterone shifts, creating a hormonal soup that amplifies pain signals. Some data shows that pain ratings for the same stimulus can jump by 20% to 30% during these times compared to mid-cycle. This gives you a clear strategy: schedule your waxing appointments for the mid-follicular phase, which is usually one to two weeks after your period starts, when higher estrogen provides a natural buffer against pain. Ignoring this is just a missed chance for a more comfortable session.

Neuroplasticity and Repeated Waxing: The Desensitization Effect

While your genes and hormones set a baseline for pain, your body is incredibly adaptive because of neuroplasticity, the brain’s ability to rewire its connections. A longitudinal study published in the Journal of Pain found that people who get waxed consistently report that it hurts much less over time. After about 3 to 6 regular sessions, participants said the pain was 25% to 40% less intense than their very first appointment. This is a physiological adaptation, not just you “getting used to it” mentally. The repeated, controlled trauma of pulling out hair seems to desensitize the nerve endings in that area and may even get the central nervous system to recalibrate its pain response. The hair follicles also weaken and the hair grows back finer, making each subsequent pull physically less of a shock. The payoff for that initial discomfort is a genuinely less painful experience down the road.

Skin Barrier Function and Inflammation: The Role of Hydration

It’s not all happening in your nerves. The actual health of your skin’s outer layer, the stratum corneum, has a big say in how much a wax hurts. If your skin barrier is compromised, meaning it’s dry, irritated, or inflamed, the process will be a lot more uncomfortable. Research in journals like the Journal of Investigative Dermatology shows that well-hydrated skin is simply more resilient. When your skin is dry, it’s less pliable, so the wax is more likely to grab onto your skin itself instead of just the hair, causing more trauma. Simply keeping your skin moisturized can reduce post-wax redness and sensitivity by as much as 15%. So that pre-wax prep and consistent moisturizing is a functional strategy to mitigate pain. A well-hydrated surface makes for a cleaner pull with less damage to the surrounding skin.

Challenging Conventional Wisdom: “Just Power Through It”

The common advice you hear about waxing is to “just power through it” or that “it’s all in your head.” Frankly, my professional experience and the scientific data show this idea is not just simplistic, it’s wrong. It’s well-intentioned, but it completely dismisses the real biological factors at work and implies pain is a failure of willpower. We know that’s false when you account for the roles of genetics and hormones. Telling someone to “power through” ignores the very real physiological differences that make waxing genuinely agonizing for some people while being just an annoyance for others. It also makes people miss out on using science-backed strategies, like timing appointments with their menstrual cycle or making sure their skin is hydrated, to actually make it better. People get scared off waxing for good because of bad advice like this. We should be giving clients knowledge about their own biology instead of dismissing their experience as a mental block. Understanding your body’s genetic predispositions and hormonal rhythms provides a real framework for managing the discomfort, turning a dreaded appointment into a strategic and more effective hair removal plan.
