Aortocaval Paraganglioma in Von Hippel-Lindau Disease

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.

A 27-year-old male with AGA and diffused thinning has been using oral Minoxidil, Finasteride, Vitamin D, B12, Iron, and Ketoconazole shampoo. Despite a hair transplant and improved blood levels, he continues to experience hair loss and suspects a possible misdiagnosis of Alopecia Areata Incognita.

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.

A 25-year-old is experiencing chronic telogen effluvium (TE) and androgenetic alopecia (AGA) after surgery, using finasteride, red light therapy, and supplements, and considering oral minoxidil despite heart concerns. They are unsure whether to start minoxidil before or after an upcoming surgery, which may trigger another hair shed.

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.

The post discusses a theory that hair regrowth after transplant is due to the angiogenesis process (new blood vessels forming), not because the transplanted hair is unaffected by DHT. The responses highlight the established belief in 'donor dominance' (the importance of the hair's origin in transplantation) and skepticism about the new theory.
