👉 Parosteosis is a medical condition that describes an abnormal growth of hair on the sides of the face, known as the parotid glands. This condition can be caused by various factors such as genetics, hormonal changes, or certain medications. It typically affects young children and adults with a history of facial trauma or overexposure to sunlight. The most common form of this condition is called "hair on the side" (parosteitis).
