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.
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.
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.
Oral minoxidil may cause dry skin and dark eye bags but doesn't significantly age the skin. Topical minoxidil is toxic to cats, and some users prefer finasteride.
Tretinoin may enhance minoxidil's effectiveness for those not responding to minoxidil alone, but it could reduce efficacy for some who are already responding to minoxidil. Tretinoin requires careful use, including skin moisturizing and sun protection due to increased sensitivity.
