The causes of hypertrichosis can be multifactorial. It can be congenital, meaning it is present at birth, or acquired later in life. Some common causes include:
- Genetic disorders: Certain genetic conditions can predispose individuals to hypertrichosis. - Medications: Drugs like cyclosporine, minoxidil, and some anticonvulsants can induce excessive hair growth. - Hormonal imbalances: Conditions such as polycystic ovary syndrome ([PCOS]()) and [Cushing's syndrome]() can lead to increased hair growth. - Metabolic disorders: Disorders like [porphyria]() can also cause hypertrichosis.
