Hypertrichosis is a rare condition characterized by excessive hair growth on the body. This can occur in various forms, affecting different areas such as the face, arms, and back. The hair can be fine and light or thick and dark, depending on the individual. The condition can be congenital, meaning it is present at birth, or acquired later in life due to factors like hormonal changes or certain medications. While hypertrichosis is not harmful to health, it can lead to psychological distress for those affected, impacting their self-esteem and social interactions.
