Pubic and Axillary Hair: The growth of
pubic hair and
axillary hair follows shortly after thelarche.

Hormonal Therapies: Used to correct hormonal imbalances.
Lifestyle Changes: Diet and exercise modifications can be beneficial, especially in cases like PCOS.
Medical Interventions: Surgery or other medical treatments may be necessary for structural or genetic abnormalities.
