“Pheromone maxxing”: the TikTok trend encouraging skipping showers and deodorant, what science says

A new variation of “maxxing” is circulating on TikTok and other social networks: “pheromone maxxing”. The idea is to avoid showering, deodorant, antiperspirant, or perfume before a romantic date in order to let a body odor, supposedly rich in “pheromones,” express itself and thus be more attractive.

The phenomenon gained visibility in early September 2026. Media outlets such as Nine, Brut, and, on September 8, The Indian Express documented videos and testimonies from young men claiming to want to “maximize” their natural scent to attract others. The vocabulary fits within the “maxxing” universe: turning a detail of the body or routine into a lever for optimizing appearance or attractiveness.

The problem is that the promise goes far beyond what research can support. Human odors can influence social perception, but this does not mean that there is an identified bodily substance capable of automatically triggering sexual attraction in another person.

In 2015, a review published in Proceedings of the Royal Society B concluded that there was no robust evidence to classify the molecules often presented as “human pheromones” as true sexual pheromones. Another review published in 2020 in Philosophical Transactions of the Royal Society B once again highlighted issues of reproducibility and the lack of solid evidence surrounding the main compounds studied.

What “pheromone maxxing” promises… and what it does not prove

In many animals and insects, pheromones are well-documented chemical signals. In humans, the situation is much more complex. Researchers have been studying chemical communication, body odors, and their possible effects on behavior for decades, but no “human sexual pheromone” has been identified as a reliable biological trigger of attraction.

In other words, a person may appreciate the natural scent of their partner, associate a fragrance with a memory, or feel more attracted to a familiar smell. But this does not allow the conclusion that not washing or deliberately letting one’s scent intensify increases the chances of seduction.

The viral shortcut is mainly due to a confusion: “natural odor” does not mean “proven sexual signal.” A subjective sensation can be real without validating the biological theory used to explain it.

Why Body Odor Becomes Stronger Without Showering

Sweat itself is not necessarily odorous. The Mayo Clinic notes that secretions from the apocrine glands, found notably in the armpits and groin, are initially odorless. The smell appears when they interact with bacteria naturally present on the skin.

Heat, humidity, clothing, and time can promote the accumulation of sweat and its interaction with skin bacteria, making the odor more noticeable. This explains why a very hot day, a workout session, or a long journey can significantly change body odor, without the need to invoke pheromones.

Deodorants and antiperspirants do not, in fact, serve exactly the same purpose. The former primarily aim to limit or mask odor, while the latter reduce the amount of sweat that reaches the skin. Neither category is mandatory for everyone: the choice depends on comfort, skin type, level of perspiration, and personal preferences.

Maintaining a natural scent does not mean neglecting hygiene

It is perfectly possible to prefer a minimalist routine, to dislike strong fragrances, or to choose an unscented deodorant. What is different is deliberately stopping washing oneself in the hope of increasing one’s attractiveness.

For daily hygiene, public recommendations remain simple: wash regularly, thoroughly dry damp areas, change clothes after heavy sweating, and prefer breathable fabrics when the heat is intense. In a hot and often humid climate like Benin, these practices are primarily a matter of comfort and moisture management, not adherence to an aesthetic standard.

Sensitive skin does not need to be stripped. Showers that are too long or very hot, as well as harsh cleansers, can irritate the skin. The right balance is therefore to stay clean without using multiple products or scrubbing excessively.

The real warning sign: an unusual change in smell

A usual body odor varies with diet, hormones, stress, heat, or physical activity. However, the Mayo Clinic advises seeking medical advice when body odor suddenly changes without a clear reason, when sweating becomes significantly heavier than before, or when it is accompanied by other unusual symptoms.

“Pheromone maxxing” can therefore remain a fun topic of conversation on social media, but not a scientific method of seduction. The most useful approach remains to distinguish a personal preference—perfume, no perfume, deodorant or not—from a biological promise presented as certain when the evidence does not support it.
