What term describes excessive hair growth that is genetically determined?

1. Hypertrichosis

2. Hypotrichosis

3. Alopecia

4. Trichotillomania

The correct answer is: Hypertrichosis

The correct term for excessive hair growth that is genetically determined is hypertrichosis. This condition is characterized by an abnormal increase in hair growth over and above the normal levels. Hypertrichosis can occur in various forms and can affect different parts of the body, potentially resulting in a notable contrast to typical hair growth patterns. The emphasis on genetic determination highlights that this condition may not necessarily be linked to external factors such as hormonal changes or environmental influences; rather, it is intrinsically connected to one's genetic makeup. This distinction is crucial for understanding the biological mechanisms that drive hair growth and the variations among individuals. The other terms provided in the choices refer to different conditions related to hair. Hypotrichosis refers to insufficient hair growth, alopecia indicates hair loss, and trichotillomania involves compulsive hair pulling. Each of these conditions has distinct characteristics and causes, which do not relate to excessive hair growth as hypertrichosis does.
