1 A new study finds girls are developing breasts earlier than ever before; American boys and girls are entering puberty about five years younger than they did in 1920.
For most girls, the second sign of puberty is the appearance of pubic hair in the pubic area. (About 10 to 15 percent will develop pubic hair before the breasts begin to bud.) At first the hair is sparse, straight and soft, but as it fills in it becomes darker, curlier and coarser.n a study of seventeen thousand girls, it was concluded that girls do not need to be evaluated for precocious puberty unless they are Caucasian girls showing breast development before age seven or African American girls with breast development before age six.
