A 27-year-old male with diffuse hair loss, including the donor area, did not respond to finasteride, dutasteride, or minoxidil. He suspects his hair loss may be linked to a mild connective tissue disorder, possibly affecting the structural support of hair follicles, rather than being purely hormonal.
The conversation discusses the delay in the PP405 Phase 2 study results, now expected by the end of 2025, and skepticism about research practices. There is also mention of optimism for Amplifica's AMP303 and a topical treatment in early testing.
Finasteride and minoxidil are used together for hair regrowth, as finasteride blocks DHT and minoxidil enhances blood flow. Some hair types require both treatments for regrowth, while others may only need one.
People are hopeful for a permanent hair loss solution by the 2030s, considering options like hair cloning and treatments like pp405. Synthetic hair transplants have been attempted but are not effective long-term.
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.
