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.
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.
Hair loss in men is primarily caused by androgenetic alopecia, with treatments like finasteride and dutasteride often recommended. Other causes include stress, nutritional deficiencies, medications, and scalp infections.
The post discusses concerns about the practicality of using Minoxidil foam for hair loss, including the frequency of application, preparation, coverage area, and drying time. Responses suggest that missing a dose isn't detrimental, it can be applied once a day, it works on all hair areas, and it doesn't need to be perfectly dry before application.
Hair loss theory suggests imbalance between Vitamin D Receptor (VDR) and Androgen Receptor (AR) activation. Proposed treatment includes upregulating VDR, downregulating AR, and improving mitochondrial health.
