When do girls start developing pubic hair?

Generally, girls grow pubic hair at around 10 to 13 years old, when menstruation begins, indicating the maturity of the ovaries. Under the stimulation of sex hormones, pubic hair gradually grows, initially sparse and soft, and its color darkens with age. If a girl has not menstruated by age 16, consideration should be given to primary amenorrhea, and she should seek medical attention promptly.

During the period of 10-13 years old, girls' ovaries gradually mature, and under the stimulation of sex hormones secreted by the ovaries, pubic hair grows slowly. Pubic hair is a secondary sexual characteristic, marking girls' gradual entry into sexual maturity. The initial emergence of pubic hair appears sparse and soft, and its color darkens with age, forming an inverted triangle above the mons pubis. In the process of development, girls usually experience the emergence of pubic hair before menstruation. Generally, puberty for females occurs at around 11-13 years old, and the secondary sexual characteristics are fully developed by the latest age of 16. If there is no development of secondary sexual characteristics by age 16, consideration should be given to congenital developmental abnormalities, and a timely hospital visit is necessary.

Usually, menstruation occurs around half a day after the emergence of pubic hair, so girls' menstruation usually occurs between 11-13 years old. If there is the development of secondary sexual characteristics but no menstruation by age 14, or no development of secondary sexual characteristics and no menstruation by age 16, consideration should be given to primary amenorrhea, and a timely visit to a doctor is recommended. Precautions: During the developmental process, girls should avoid consuming stimulating foods, especially cold foods, to prevent dysmenorrhea during menarche. At the same time, attention should be paid to breast development, and a comprehensive judgment should be made based on factors such as height, age, etc., to determine whether there are symptoms of precocious puberty.
