Hair Loss and Genetics
Researchers suspect that several genes inherited from both parents play a role in androgenetic alopecia. Paternal hair loss has been shown to correlate with chances of alopecia in sons, while variations in the androgen receptor gene (AR), which can also correlate with baldness, are X linked and thus inherited from one's maternal grandfather or grandmother or both.

Receptors of Androgen allow the body to respond appropriately to dihydrotestosterone and other androgens. Studies suggest that variations in the AR gene lead to increased activity of androgen receptors in hair follicles. It remains unclear, however, how these genetic changes increase the incidence of patterned hair loss in men and women with androgenetic alopecia.
The actual inheritance pattern of androgenetic alopecia or male pattern baldness is unclear because many genetic and environmental factors are likely to be involved. This condition tends to cluster in families, however, and having a close relative with patterned hair loss appears to be a risk factor for developing the condition.
