Androgenetic Alopecia: Just a Cosmetic Defect or a Biomarker and Risk Factor for Systemic Diseases? Literature Review

Pattern hair loss before age 35 may be linked to higher risks of prostate cancer, cardiovascular diseases, and metabolic syndrome later in life. Finasteride is discussed as a treatment that may lower PSA levels and potentially prevent prostate issues.

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

A 31-year-old man with androgenic alopecia is considering treatments like finasteride, minoxidil, and ketoconazole shampoo but is worried about finasteride's side effects. Users recommend starting with finasteride or dutasteride for DHT blocking, suggesting topical solutions to reduce side effects.

Male pattern baldness (MPB) may be an early warning sign for type 2 diabetes due to its association with insulin resistance. Treatments discussed include testosterone therapy and finasteride, which affects hormone levels related to hair loss and insulin sensitivity.

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.
