Which of the following terms describes hair growth that is abnormal for a person's age and sex?

• A. Hirsutism
• B. Superfluous hair
• C. Hypertrichosis
• D. Alopecia

Answer: (A)

The term that describes hair growth that is considered abnormal for a person's age and sex is hirsutism. Hirsutism specifically refers to excessive or unwanted hair growth in women, typically in areas where men usually grow hair, such as the face, chest, and back. This condition is often due to hormonal imbalances, particularly involving androgens, which can lead to the development of male-pattern hair growth in females.

On the other hand, superfluous hair generally refers to any excessive hair growth but does not specify the context related to age or sex. Hypertrichosis is a broader term that describes excessive hair growth anywhere on the body regardless of the person's age or sex and can be a genetic condition. Alopecia refers to hair loss and is unrelated to excessive hair growth; it describes conditions where hair is lost from some or all areas of the body.
