Body hair really gets going during puberty. Some boys will start to notice hair growing on their face around the chin, on the cheeks, and above the lip. Also, hair grows on the chest, the armpits, and even down there in the pubic region.
Two of the most significant differences between puberty in girls and puberty in boys are the age at which it begins, and the major sex steroids involved, the testosterones and the estrogens. Although there is a wide range of normal ages, girls typically begin the process of puberty at age 10 or 11; boys at ages 11â12.
