At What Age Do Girls Start to Develop Body Hair?
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.
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.
