Urban pollution and sun exposure speed up skin aging and wrinkle formation in Chinese women, with pollution's effects becoming significant after age 45.
The conversation discusses whether sunlight exposure affects hair growth or loss, with mixed anecdotes and theories but no clear consensus. Some suggest moderate sunlight can benefit hair by providing vitamin D, while others doubt its effectiveness compared to treatments like Minoxidil or finasteride.
The conversation is about making topical finasteride using ethanol. The user is advised to use non-denatured or food-grade ethanol, as denatured ethanol may be harmful with prolonged skin exposure.
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.
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.
Concerns about the long-term safety of VDPHL01, an extended-release minoxidil, due to potential risks similar to Cantu syndrome, were raised, highlighting the lack of monitoring for chronic connective tissue changes. The conversation suggests that while the treatment may improve hair growth, it could lead to issues not detected in short-term trials.
