Comparative Biology of Tissue Repair, Regeneration, and Aging

Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

A permanent hair loss solution could involve reprogramming hair follicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.

CRISPR shows promise for treating hair loss by targeting specific genes. Current treatments include Minoxidil and finasteride, but CRISPR could offer a more precise solution, though it is still expensive and in early stages.

Promising hair loss treatments in 2026 include GT20029, a topical androgen receptor degrader, and VDPHL01, an extended-release oral minoxidil, both offering safer alternatives with fewer side effects. Other treatments like sublingual minoxidil, OND-1, JW0061, TDM-105795, and AMP-303 are also being explored.

Federal funding cuts have delayed PP405 research, affecting hair loss treatment progress, though clinical trials will continue. The discussion highlights PP405's potential compared to minoxidil and finasteride and stresses the importance of government-funded research.
