Unwanted hair, also referred to as excessive or abnormal hair growth, occurs when hair appears in areas where it is not desired or grows at an accelerated rate due to factors such as hormonal imbalances, genetics, or underlying medical conditions. While body and facial hair are natural, excessive, thick, or coarse hair can become a cosmetic concern, leading to frustration and frequent maintenance. This condition can affect both men and women, with common problem areas including the face, arms, legs, chest, back, underarms, and bikini line. Hormonal fluctuations, aging, certain medications, and conditions like polycystic ovary syndrome (PCOS) can all contribute to increased hair growth.
