- Pubic-hair growth in girls is considered early when the girl is younger than eight years old. (See References 1)
- Causes of early public-hair growth in girls include infections (such as meningitis), tumors or a malfunctioning hypothalamus. However, for some girls, there is no known cause. (See References 1)
- To identify the cause of early public-hair growth in a girl, a doctor will order a urine and blood test to determine if sex hormones are elevated. The doctor will then perform a CT scan and MRI to see if the child has a tumor. (See References 1)
- If an underlying condition is identified, treatment may include medications. LHRH analog medications contain synthetic hormones that stop a girl's body from producing the sex hormones that cause her to grow pubic hair. (See References 1)
- Girls who develop pubic hair early may have other signs of early puberty, such as menstruation and breast development. (See References 2)
