Which term refers to a condition characterized by excessive hair growth all over the body, which can be present at birth or develop later and can affect men and women?

• A. Vellus hair
• B. Superfluous hair
• C. Hypertrichosis
• D. Topical

Answer: (C)

Excessive hair growth all over the body, whether present at birth or developing later and affecting both men and women, is described by hypertrichosis. This term covers abnormal hair growth beyond what’s normal and can be generalized or widespread. Normal fine body hair that’s normally present is called vellus hair, so it isn’t considered a condition. The phrase superfluous hair is a non-technical way to describe extra hair but isn’t the clinical label for the condition. Topical refers to something applied to the skin, not to a hair growth disorder.
