Effect of Heat Treatment on Human Hair Keratin Film

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.

The conversation discusses the lack of public information on the chemical structure of PP405, a hair loss treatment, and the challenges of synthesizing it without a patent. It also explores a patent related to hydrogen-based topical formulations for reducing oxidative stress and inflammation.

Topical 2-deoxy-D-ribose (2dDR) regrows hair in mice almost as well as 2% Minoxidil. However, 2dDR may contribute to oxidative stress and hair loss due to the formation of advanced glycation end products (AGEs).

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.

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.

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.
