Autotaxin-LPA Signaling Contributes to Obesity-Induced Insulin Resistance in Muscle and Impairs Mitochondrial Metabolism

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.

PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

Adipose-derived stem cells with ATP improved hair regrowth in male and female mice with androgenetic alopecia. The most effective treatments were low dose stem cells with ATP for males and medium dose stem cells with non-liposomal ATP for females.

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.

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.
