Intracellular and Extracellular Signaling Between Dermal Papilla Cells and Hair Follicle Epithelial Cells

The conversation discusses using hair follicle dermal papilla exosomes for hair loss treatment. It inquires about purchasing options for this treatment.

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.

Adipose fat cells and stem cells may help treat hair loss by restoring the scalp's thickness. Treatments like NanoFat injections and Botox are discussed for their potential to promote hair growth.

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.

A new "third cell" discovery in Japan could be key to fully regenerating hair follicles, with human trials possibly starting in 2027-2028. AI is expected to accelerate medical discoveries, potentially leading to a hair loss cure within a few years.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.
