Preventing hidradenitis suppurativa flare-ups requires a combination of lifestyle changes, skin care habits, and in some cases medical treatment. HS flares begin when hair follicles become blocked, rupture beneath the skin, and trigger an intense inflammatory response. You can’t cure HS, but you can significantly reduce how often and how severely flares strike by targeting the factors that set off that cycle.
Why Flares Happen
The root problem in HS is the hair follicle. Follicles in areas like the armpits, groin, and under the breasts become clogged, then rupture below the skin surface. Your immune system treats the released material like a foreign invader, launching an aggressive inflammatory reaction that produces the painful nodules, abscesses, and tunneling tracts characteristic of a flare. Anything that increases follicular blockage, skin friction, sweating, or systemic inflammation can tip this process into motion.
Dietary Changes With the Strongest Evidence
Diet is one of the most actionable levers for flare prevention, and the research points to a few specific culprits. In a survey of 728 HS patients, those who identified foods that worsened their symptoms most commonly named sweets (68%), bread and pasta (51%), dairy (51%), and high-fat foods (42%). These aren’t random associations. Elimination studies back them up.
In one study, 83% of 47 HS patients placed on a dairy-free diet experienced clinical improvement compared to a control group with no dietary restrictions. A separate study found that patients on a combined low-dairy, low-carbohydrate diet saw measurable improvement in disease severity staging.
Brewer’s yeast is another trigger worth knowing about. It shows up in beer, bread, and some fermented foods. Among 37 patients who followed a yeast-exclusion diet, 70% reported improvement. The striking detail: 87% of those who went back to eating yeast-containing foods saw lesions return within a week. If you’re looking for a place to start, cutting back on dairy, refined carbohydrates, and brewer’s yeast for several weeks is a reasonable first experiment.
Clothing and Friction Management
Friction and trapped moisture are reliable flare triggers, especially in warm weather. Breathable fabrics like cotton, bamboo, and linen allow air to circulate and reduce sweat buildup in skin folds. Moisture-wicking athletic fabrics are another good option for pulling sweat away from the skin before it pools in problem areas.
Loose, flowy clothing consistently outperforms anything tight or restrictive. For women, soft bralettes or going braless can reduce irritation under the breasts. Flowy dresses paired with biker shorts or long underwear underneath help prevent thigh chafing without sacrificing airflow. Applying a thin layer of zinc oxide cream or talc-free body powder to friction-prone spots adds another layer of protection.
Skin Care to Reduce Bacterial Load
Antimicrobial washes aim to keep skin and follicle bacteria in check, reducing the chance that a blocked follicle escalates into a full inflammatory event. Options include chlorhexidine wash, benzoyl peroxide wash, zinc pyrithione wash, and dilute bleach (sodium hypochlorite) body wash. These are used across all stages of HS as a low-risk daily maintenance strategy.
One approach gaining traction is a 0.006% sodium hypochlorite body wash used daily during bathing. In real-world use, patients applied it as part of their regular shower routine, sometimes also dabbing it directly on active areas between showers. The goal with any antimicrobial wash isn’t to sterilize the skin but to keep bacterial overgrowth from compounding the inflammation that HS already creates. Whichever wash you choose, gentle application matters. Scrubbing aggressively can damage the skin and make things worse.
Weight Loss and Its Impact
Excess weight increases skin-on-skin friction, traps heat and moisture, and promotes systemic inflammation, all of which feed the HS cycle. The data here is concrete: among patients who lost weight, 35% fewer reported ongoing HS symptoms afterward, and the average number of affected body sites dropped from nearly two to about one. The threshold for meaningful improvement appears to be a weight loss of more than 15% of body weight. That’s a significant amount, but it correlates with a significant reduction in disease severity. Even modest weight loss can reduce friction in skin folds, so any progress in this direction is likely to help.
Hormonal Treatment for Women
Hormones play a clear role in HS. Many women notice flares worsening around their menstrual cycle, and androgen hormones (the same hormones involved in acne and excess hair growth) appear to drive follicular plugging in HS. Anti-androgen medications can help stabilize this.
Spironolactone is the most commonly studied option, used exclusively in female patients at doses that typically start low and may go up to 100 mg daily. Multiple studies across hundreds of women show improvement. Finasteride, another anti-androgen, has been used at 5 mg daily as a standalone treatment in smaller studies involving both women and men, with generally good tolerability. Some women benefit from specific combined oral contraceptives that contain anti-androgenic components. If your flares clearly track with your cycle, bringing this up with your dermatologist opens a category of treatment that directly addresses one of HS’s root drivers.
Zinc Supplementation
Oral zinc gluconate at 90 mg daily has shown enough benefit in HS that European guidelines list it as a second-line maintenance treatment. The relationship between zinc and flare prevention appears dose-dependent. Studies found that when patients in remission had their zinc reduced from 90 mg to 60 mg or lower, lesions relapsed. This suggests zinc needs to stay at the higher dose to maintain its effect. Taking zinc on an empty stomach can cause nausea, so pairing it with food helps. Because 90 mg is well above the standard recommended daily intake, this is worth discussing with a provider to monitor for side effects like copper depletion over time.
Stress Reduction
Stress is one of the most commonly reported flare triggers among HS patients, and the mechanism is straightforward. Psychological stress raises cortisol and other stress hormones, which amplify inflammatory signaling throughout the body. For a condition already driven by an overactive immune response, this added fuel can push a quiet period into a full flare. There’s no single “right” stress management technique, but the principle matters: anything that reliably lowers your stress load, whether that’s exercise, therapy, sleep hygiene, or meditation, is functioning as flare prevention.
Medical Maintenance Therapy
When lifestyle changes alone aren’t enough, maintenance medications can reduce flare frequency. Oral antibiotics, particularly tetracyclines, are a common first step. They work partly through their anti-inflammatory properties, not just their antibacterial effects. For moderate to severe HS that doesn’t respond to standard treatments, biologic injections that target specific parts of the immune system have been approved. These are typically self-administered at home on a set schedule and work by dampening the overactive inflammatory pathways that drive HS. They’re reserved for cases where first and second-line approaches haven’t provided adequate control, but for the right patients, they can dramatically reduce flare frequency and severity.
The most effective flare prevention strategy combines several of these approaches simultaneously. Changing your diet, managing friction, using an antimicrobial wash, and addressing weight or hormonal factors together will generally outperform any single intervention on its own.
