What type of alopecia is commonly referred to as male pattern baldness?

1. Alopecia areata

2. Alopecia senilis

3. Androgenetic alopecia

4. Diffuse alopecia

The correct answer is: Androgenetic alopecia

Androgenetic alopecia is the medical term for what is commonly known as male pattern baldness. This condition is characterized by a gradual thinning of hair, typically beginning at the temples and crown of the head. It is largely influenced by genetic factors and hormonal changes, particularly involving androgens, which are hormones that regulate hair growth. The condition can occur in both men and women, but it manifests differently. In men, it often leads to a receding hairline and thinning on the crown, while in women, it usually results in general thinning across the scalp. Recognizing this specific type of alopecia is important for understanding its causes and exploring potential treatments. The other types of alopecia mentioned do not specifically refer to male pattern baldness. Alopecia areata is an autoimmune condition that leads to sudden hair loss in patches. Alopecia senilis relates to hair loss associated with aging, and diffuse alopecia refers to widespread thinning across the scalp. Each of these conditions has different underlying causes and presentations, distinguishing them from androgenetic alopecia.
