Protein Kinase C Epsilon Is Linked to 12-O-Tetradecanoylphorbol-13-Acetate-Induced Tumor Necrosis Factor-Alpha Ectodomain Shedding and the Development of Metastatic Squamous Cell Carcinoma in Protein Kinase C Epsilon Transgenic Mice.

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.

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.

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.

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.

ABS-201 may block prolactin receptors in hair, potentially reducing androgen receptors and affecting hair loss. It could also aid collagen synthesis and stem cell pathways, similar to GHK-Cu.
