Supplementary Figure 2 From Male-Pattern Vertex Baldness Trajectories, Chest Hair Patterns, and Odds of Overall and Aggressive Prostate Cancer

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.

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.

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

Male Pattern Baldness, and identifying early signs of it. The treatments discussed to combat and slow balding include finasteride, dutasteride and minoxidil.

A 25-year-old male experienced significant hair loss due to telogen effluvium and androgenetic alopecia. He began using finasteride, minoxidil, and vitamins, seeing some regrowth but remains worried about hair density.
