Keratins as Mediators of Glucose Sensing in the Pancreas

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.

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.

High sugar diets may worsen hair loss by increasing 5α-reductase activity and androgen levels, especially in women with PCOS. A low sugar diet might reduce scalp DHT levels, similar to finasteride, but genetics also significantly influence hair loss.

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.

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.

A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.
