When do girls grow hair?

Both girls and boys will begin to develop at a certain stage. Generally, girls' development is divided into several steps. First, breasts appear, and finally pubic hair and head hair begin to grow. There is no pubic hair before the age of ten. Around the age of 10 to 11, there will be sparser pubic hair, and by the age of 18, it will be completely formed.

Pubic hair is a secondary sexual characteristic of humans. During female puberty, there are two more prominent developmental characteristics: one is breasts, and the other is the growth of pubic hair.

The growth of female pubic hair is divided into six stages:

In the first stage, before the age of 10, there is no visible pubic hair.

The second stage, around 10-11 years old, is when pubic hair begins to grow sparsely, long, and soft, and is slightly curly.

The third stage, from 12 to 13 years old, is when the pubic hair increases in number and gradually becomes curly, thicker and darker in color.

Stage 4, 14-15 years old, pubic hair expands to cover the labia.

The fifth stage, 16-17 years old, the pubic hair expands to the pubic area and becomes adult type.

In the sixth stage, at the age of 18, the pubic hair is distributed in a typical inverted triangle shape to the inner thighs.
