Why Does Male Pattern Baldness Occur?

Male pattern baldness, known as androgenetic alopecia, affects men more commonly than women. This condition is characterized by hair loss, typically at the top and front of the scalp.

Recent research has emphasized the role of genetic predisposition to baldness, suggesting a strong hereditary influence with genes from both maternal and paternal lineages contributing to the development of this condition.

Hormonal factors, particularly dihydrotestosterone (DHT), have also been implicated in male pattern baldness. DHT, a potent form of testosterone, binds to receptors in hair follicles, causing their shrinkage and eventual cessation of hair growth, primarily on the scalp.

In addition to genetic and hormonal influences, the sensitivity of hair follicles to DHT varies across the body, with hair follicles on the scalp exhibiting heightened sensitivity to DHT, whereas follicles in other regions of the body are less affected.

Male pattern baldness is a complex interplay of genetic predisposition, hormonal activity, and follicular sensitivity, leading to differences in baldness patterns among males.
