However, it is known that by the early 1900s, being "clean-shaven" had become associated with basic hygiene, and concerns about personal appearance have often motivated hair removal practices. In the 1920s, the new fashion for sleeveless tops and short dresses meant that the legs and armpits of American women were now visible in social situations, and advertisers seized the opportunity to encourage women to shave their legs and their armpits.
The search results also provide information on products and techniques for shaving armpit hair. Some tips for shaving armpits include soaking the underarms in warm water to soften the skin and hair, cleaning the armpits before shaving to ensure they are clear of sweat and deodorant, and shaving lightly in short strokes in all directions.
