excessive growth of fine, soft, unpigmented hair
Hypertrichosis Lanuginosa is a rare condition characterized by the excessive growth of fine, soft, and unpigmented hair, known as lanugo, which typically covers the body of a fetus and is usually shed before birth. In individuals with this condition, the lanugo hair persists or reappears later in life, often as a result of genetic factors or as a symptom of certain medical conditions, such as cancer or metabolic disorders.
