Skin Metabolism in Obesity: A Narrative Review

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

Being overweight may increase finasteride side effects due to higher aromatase activity converting testosterone to estradiol. Maintaining a healthy weight could reduce these side effects.

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 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.

Male pattern baldness (MPB) may be an early warning sign for type 2 diabetes due to its association with insulin resistance. Treatments discussed include testosterone therapy and finasteride, which affects hormone levels related to hair loss and insulin sensitivity.

Akkermansia bacteria can improve hair growth inhibited by testosterone, and metformin may increase Akkermansia, which could help with hair loss related to aging, insulin resistance, and inflammation.
