  https://www.ncbi.nlm.nih.gov/books/NBK278957/

  Male androgenetic alopecia (MAA) is the most common form of hair loss in men, affecting 30-50% of men by age 50. MAA occurs in a highly reproducible pattern, preferentially affecting the temples, vertex and mid frontal scalp. […] Hair loss impacts self-image and is a great cause of anxiety and depression in some men. MAA is increasingly identified as a risk factor for arterial stiffness and cardiovascular disease. […] The key pathophysiological features of MAA are alteration in hair cycle development, follicular miniaturization, and inflammation. In MAA, the anagen phase decreases with each cycle, while the length of telogen remains constant or is prolonged. Ultimately, anagen duration becomes so short that the growing hair fails to achieve sufficient length to reach the surface of the skin, leaving an empty follicular pore. Hair follicle miniaturization is the histological hallmark of androgenetic alopecia. Once the arrector pili muscle, that attaches circumferentially around the primary follicle, has detached from all secondary follicles and primary follicles have undergone miniaturization and detachment, hair loss is likely irreversible.

  https://www.ncbi.nlm.nih.gov/books/NBK278957/

  Male androgenetic alopecia (MAA) is the most common form of hair loss in men, affecting 30-50% of men by age 50. MAA occurs in a highly reproducible pattern, preferentially affecting the temples, vertex and mid frontal scalp. […] Hair loss impacts self-image and is a great cause of anxiety and depression in some men. MAA is increasingly identified as a risk factor for arterial stiffness and cardiovascular disease. […] The key pathophysiological features of MAA are alteration in hair cycle development, follicular miniaturization, and inflammation. In MAA, the anagen phase decreases with each cycle, while the length of telogen remains constant or is prolonged. Ultimately, anagen duration becomes so short that the growing hair fails to achieve sufficient length to reach the surface of the skin, leaving an empty follicular pore. Hair follicle miniaturization is the histological hallmark of androgenetic alopecia. Once the arrector pili muscle, that attaches circumferentially around the primary follicle, has detached from all secondary follicles and primary follicles have undergone miniaturization and detachment, hair loss is likely irreversible.
