Step-by-step explanation:
In androgenetic alopecia, a combination of heredity, hormones, and age causes hair loss. This condition is characterized by progressive hair loss and reduced hair regrowth. Heredity plays a significant role in androgenetic alopecia, as certain genes can make individuals more susceptible to the condition. Hormones, such as androgens, can also contribute to hair loss by affecting the hair follicles. As people age, changes in hormone levels and reduced hair growth cycles can further contribute to hair loss.
