Women have removed underarm hair in various cultures for many centuries, but it became a broad social norm for Western women only in the early 1900s.

Quick Scoop: The Short Answer

If you’re asking “when did women start shaving their armpits” in the sense of a modern Western beauty expectation , the turning point was the 1910s–1920s.

That’s when sleeveless fashion, new safety razors, and aggressive marketing converged to make hairless underarms the “proper” look for middle‑class women.

But if you zoom out historically, women’s underarm and body hair removal shows up in ancient Egypt, medieval Europe, and Islamic societies long before that, just not as a universal, gendered norm like today.

Deep History: Long Before the 1900s

Even though the phrase “when did women start shaving their armpits” sounds modern, body hair removal goes way back.

  • Ancient Egypt: Elite women and priests used flint or bronze razors, tweezers, and even sugaring‑like pastes to remove body hair, including underarms, as part of cleanliness and status rituals.
  • Classical and medieval worlds: European and Middle Eastern texts mention women removing body hair (often “everything below the head”), for ideals of youth, beauty, and purity.
  • Medieval Islam: Hair removal—including underarms—was tied to ritual cleanliness alongside nail cutting and beard care.

These practices were common in certain classes and cultures , but they were not a single global standard or specifically “all women must shave armpits” in the modern sense.

The Modern Shift: 1910s–1920s

The social norm most people mean by “when did women start shaving their armpits” really crystallized in the early 20th century, especially in the United States and Western Europe.

Key moments:

  1. Fashion changes (mid‑1910s)
    • Sleeveless and lower‑cut dresses became newly fashionable, exposing the underarm in public in a way it hadn’t been for centuries.
 * That suddenly made visible underarm hair something for advertisers to frame as a “problem.”
  1. Women’s razors hit the market
    • Companies like Gillette launched razors marketed specifically to women, just as shorter, sleeveless styles took off.
 * Advertising pitched underarm hair as “unsightly” or unfeminine and linked shaving to being modern, hygienic, and respectable.
  1. Media reinforcement
    • In 1915, a Harper’s Bazaar article promoted underarm hair removal for women wearing the new sleeveless styles, framing smooth armpits as part of a “clean” look.
 * By the 1920s, the trend had spread widely in the urban middle class; underarm shaving became a normalized part of women’s grooming.

By the 1940s–1950s, in much of the U.S., a woman with visible underarm hair could be seen as unkempt or even defiant of gender norms.

Beyond “When”: Why It Became a Norm

The “why” behind “when did women start shaving their armpits” is mostly cultural, not medical.

  • Beauty standards and femininity
    • Ads and magazines framed hairless underarms as more feminine, refined, and attractive, sometimes promising “unexpected charm” or romantic success.
  • Hygiene rhetoric
    • Marketers leaned on ideas of “freshness” and “cleanliness,” even though men with underarm hair weren’t labeled unhygienic in the same way.
  • Consumer culture
    • The norm conveniently supported sales of razors, depilatory creams, and later waxing and laser treatments.

In other words, the social rule that “women should shave their armpits” is a relatively recent, commercialized expectation layered on top of much older grooming traditions.

Today: Norms, Pushback, and “Latest News” Vibes

In the 21st century, the question “when did women start shaving their armpits” often comes up in debates about gender norms and body autonomy.

  • Many women in Western countries still shave or remove underarm hair as a default habit, often starting in early teens.
  • At the same time, there’s a visible pushback: from celebrities and influencers showing natural underarm hair to social media discussions about rejecting “mandatory” shaving as a beauty rule.
  • Online forums and Q&A communities regularly dissect where the expectation came from and why it is applied so differently to men and women, treating it as an ongoing cultural topic rather than settled tradition.

So the timeline looks something like this:

  • Ancient and medieval periods: Various cultures, especially elites, practice body hair removal including underarms, but not as a universal female norm.
  • 1910s–1920s: In the West, visible underarms plus new razors plus targeted advertising turn shaved pits into a mainstream expectation for women.
  • Mid‑20th century onward: The norm solidifies, then gradually becomes something younger generations question, remix, or reject.

TL;DR: Women have removed underarm hair in different cultures for many centuries, but the widespread Western expectation that women should shave their armpits dates mainly from the 1910s–1920s, driven by fashion changes and advertising, and it’s now an active topic of debate and re‑negotiation rather than a timeless rule.
