Photo-Downregulation of SIRT4 Mitigates Aging in Mice by Enhancing H3K9ac via Fatty Acid 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.

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.

The user does not respond well to minoxidil and is seeking an alternative to Tretinoin to upregulate sulfurtransferase activity for hair loss treatment. No specific alternative treatments were mentioned.

Korean scientists developed a red light therapy that reduces a hair loss marker by 92%. Users discussed the benefits and drawbacks of natural sunlight versus red light caps for hair health, with some suggesting supplements for vitamin D.

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.

Microneedling and tretinoin may enhance minoxidil absorption for hair loss, but evidence on their effectiveness is limited. Iron supplements and broccoli sprouts are suggested for enzyme activation, but their impact on hair is unclear.
