Why do you become more hairy as you get older?

As people age, hormonal changes, particularly increases in androgens, can lead to increased hair growth in certain areas, such as the face and ears for men and women. Additionally, hair follicles may become more sensitive to these hormones, resulting in thicker or coarser hair. Conversely, other areas, especially the scalp, may experience hair thinning or loss due to a decrease in hair follicle activity. Overall, the balance of hormonal influences and changes in hair follicle health contribute to increased hairiness with age.
