A growing number of young men on TikTok have stopped showering, ditched deodorant, and quit washing their hair before dates, convinced their raw body odor will make women swoon, a strategy experts say has no scientific support.
They call it "pheromone-maxxing." The idea, circulating on TikTok among Gen Z men, is simple: ditch every hygiene product, let your natural scent build up, and wait for the compliments to roll in. One user claimed he "stopped using cologne" and started "getting more compliments on my disgusting onion smell than ever." Another posted on TikTok that "the reason you can't pull baddies is because you wear cologne and deodorant."
The trend sits inside a broader online subculture known as "looksmaxxing," where young men pursue sometimes extreme measures to optimize their physical appearance. Past looksmaxxing advice has included "bonesmashing", repeatedly striking one's own face to reshape bone structure, and self-injected filler, both debunked and dangerous. Pheromone-maxxing is the latest offshoot, and while it skips the physical harm, it trades one form of bad advice for another.
Dr. Shereen Teymour, a board-certified dermatologist in New York, did not mince words. She told USA TODAY the trend misreads real science and runs it off a cliff:
"Pheromone-maxxing takes a kernel of legitimate science, the fact that humans produce individual chemical odors and that smell can influence how we perceive other people, and stretches it into a conclusion the science doesn't support."
Her blunter summary landed harder. Skipping showers, she said, is not pheromone-maxxing, "for the most part, it's bacteria-maxxing." When you stop bathing, what accumulates on the skin is not some primal chemical signal. It is bacteria breaking down sweat, producing the odors most people associate with a locker room, not a first date.
Teymour also pushed back on the all-or-nothing framing popular in the trend's TikTok videos. Good hygiene, she said, does not mean scrubbing away every trace of natural scent or wrecking the skin's microbiome. It means "keeping the skin clean, comfortable and healthy." That is a far cry from swearing off soap.
Pamela Dalton, a psychologist and olfactory scientist at the Monell Chemical Senses Center, addressed the core claim directly. Pheromones drive mating behavior in insects and some mammals. Humans are a different story.
"Human chemical communication does not really influence behavior in the same way that pheromones in other species do."
That distinction matters. Pheromone-maxxing advocates treat animal biology as a one-to-one map for human attraction. Dalton's research says it is not. While body odor may play some role in how people perceive one another, particularly with an intimate partner, she noted that a stranger finding your unwashed scent appealing is rare. The leap from "smell can matter" to "stop showering and women will flock to you" has no bridge in the published science.
Fox News reported that Scientific American has stated flatly: "There is no evidence of a consistent and strong behavioral response to any human-produced chemical cue." A frequently cited 1995 "sweaty T-shirt study" did find that women preferred the body odors of men whose immune-system genes differed from their own, but a 2020 analysis found no strong evidence supporting that preference in broader populations.
The trend's more committed followers take things further than just laying off the Old Spice. The New York Post reported that some proponents wear unwashed shirts on dates, hoping the accumulated scent will work as a natural attractant. Others have reportedly gone so far as to drink their own urine, claiming it helps them "sweat out toxins", a claim with zero basis in medical science.
The trend has been circulating online since at least 2024 and appears to have gained fresh momentum on TikTok, where "pheromone perfume" advertisements, products marketed as bottled attraction, have racked up millions of views. The overlap between the perfume ads and the anti-shower crowd is ironic: one side sells you a product to smell irresistible, and the other tells you to smell like nothing at all. Neither has the science to back it up.
Fox News panelist Tyrus offered a more practical take on the hygiene question: "You don't want to smell like gym class, but you also don't want to smell like you're cheap." That lands closer to common sense than anything the pheromone-maxxing crowd has produced.
USA TODAY noted that the trend does not appear to be widespread. But "not widespread" and "harmless" are not the same thing. The looksmaxxing pipeline has a pattern: a real insecurity meets bad online advice, which gets packaged in confident TikTok delivery and passed off as hidden knowledge. Bonesmashing. Self-injected filler. Now skipping basic hygiene. Each iteration targets young men who feel they are losing a game no one explained the rules to.
The pheromone-maxxing trend is not dangerous in the way bonesmashing is. Nobody is going to the emergency room because they skipped a shower. But it reflects something worth paying attention to: a generation of young men so starved for practical guidance on dating and self-presentation that they will take grooming advice from anonymous TikTok accounts over board-certified doctors.
Dr. Teymour and Dalton both pointed to the same gap. Real science says human scent can play a minor, context-dependent role in attraction. TikTok influencers took that sliver and built an entire lifestyle around it, one that tells young men the path to confidence runs through a week of unwashed armpits.
When a culture's young men are getting their self-improvement advice from people who recommend drinking urine, the problem is not hygiene. It is the absence of anyone credible willing to tell them the truth, and a generation too online to go looking for it.
