At What Age Do Girls Start to Develop Body Hair?

Update Date: 2024-05-24 Source: Network

Girls generally enter puberty at around 11 to 12 years old, during which a series of bodily changes occur, such as the development of sexual organs, the emergence of secondary sexual characteristics, and the complete maturation of reproductive functions. Height and weight increase rapidly, and the functions of various organs in the body tend to mature. The adrenal glands begin to secrete estrogen, stimulating hair growth and the appearance of pubic hair and underarm hair.

Underarm hair, located under the armpits, is also one of the secondary sexual characteristics of women. Similar to pubic hair, it is the result of the adrenal glands beginning to secrete androgen. The appearance of underarm hair is generally 1 to 2 years later than pubic hair, and Chinese women typically develop underarm hair after 14 to 15 years old.

Once underarm hair grows in the armpits, the area is often sweaty. Compared to childhood, the sweat now has a special odor. If not cleaned in time, it will soon emit an unpleasant smell, commonly known as body odor. If frequent bathing and changing clothes do not improve this condition, it is best to consult a dermatologist. Some people believe that when wearing short-sleeved shirts in summer, exposing underarm hair is not aesthetic, so they use scissors to cut it off, or even use a razor to shave it. However, this is actually incorrect and harmful to health.

Regardless of whether you cut or shave your underarm hair, it cannot prevent the normal emergence of this physiological phenomenon. Moreover, it can easily lead to bacterial infections in the armpits. Therefore, we should face this normal physiological phenomenon of underarm hair squarely.
