Reexamining the Role of Diet in Dermatology

Controlling insulin levels through intermittent fasting and a low glycemic diet may improve hair quality by reducing androgens. It's important to maintain proper nutrition, including electrolytes and protein, during fasting.

Insulin resistance may increase DHT production, contributing to hair loss, and addressing it through diet, nutrients, and natural DHT blockers like saw palmetto and pumpkin seed oil could help reverse hair loss. Some users prefer medications like finasteride for more effective results.

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.

Ketoconazole shampoo does not significantly reduce systemic or scalp DHT levels and is considered a mild topical antiandrogen. Users discuss its use for scalp health rather than DHT reduction, with some preferring alternatives like dutasteride over finasteride due to perceived side effects.

Creatine may increase DHT levels, potentially causing symptoms like acne, oily hair, and hair shedding. Users report mixed experiences, with some avoiding creatine due to hair loss concerns and others seeing no impact.

A 57-year-old man with male pattern hair loss and insulin resistance experienced hair regrowth and weight loss after using tirzepatide, without other hair treatments. Dysregulated glucose metabolism is linked to hair loss, with tirzepatide potentially improving hair density by normalizing insulin resistance.
