TikTok's 'pheromone maxxing' trend skips showers, deodorant, and hygiene before dates. Scientists say there is no evidence humans secrete or detect pheromones.
A new TikTok trend called "pheromone maxxing" has users skipping showers, ditching deodorant, wearing sweaty shirts, and even drinking their own urine before dates. The idea is to boost natural "sex pheromones" to make oneself biologically irresistible. But the scientific community is pushing back hard: there is no clear evidence that humans secrete or can detect pheromones the way animals do.
The trend is the latest in a series of "maxxing" fads on social media, following ballmaxxing, climaxxing, and fibermaxxing. While some of those, like fibermaxxing, have a basis in real science, pheromone maxxing rests on a shaky belief that humans work like ants, moths, or mice.
Pheromones are chemicals that trigger social responses in certain animals. Alarm pheromones warn of danger; food trail pheromones lead to meals. Sex pheromones attract mates and trigger mating behaviors. The logic behind pheromone maxxing is that staying dirty maximizes one's "natural musk," making the wearer irresistible.
The biological problem is fundamental. Scientists have not isolated human sex pheromones from any part of the body. The same issue surfaced last year with the "vabbing" trend–dabbing vaginal secretions on pulse points–which also lacked scientific backing, as I covered in Forbes.
Even if humans did secrete pheromones, they may lack the equipment to detect them. The vomeronasal organ (VNO) inside the nose is used by other mammals to process pheromones, but the human VNO is relatively small and likely too underdeveloped to do the same job.
Sensing and liking a smell is not the same as reacting to a pheromone. Pumpkin spice may trigger fond memories, but that is psychological association, not chemical signaling. If you once dated someone who smelled like Pig Pen from Peanuts, a stinky date might bring back memories–but that is about association, not stimulation.
When you skip a shower, you cannot select what stays on your body. Everything accumulates: dirt, crumbs, and potentially alarm pheromones if they exist in humans. Signaling "danger" to a date is probably not the goal. Food trail pheromones could send a very different message.
Drinking urine as part of the trend carries real health risks. Urine contains waste products and harmful microbes that should not re-enter the body. Despite what the movie "Dodgeball" suggests, urine is not sterile. The same risks were highlighted in 2022 when an anti-vaxx website claimed urine could treat COVID-19.
Experts advise against the trend entirely. Personality, they say, is a more effective dating strategy than unscientific and unsanitary practices.
