TLDR Transplanted skin on hooded rats often grows white hair instead of black.

In a study on hooded rats, researchers observed that skin transplanted from areas producing black hair often grew white hair in its new location. This change was also noted when the skin was sutured back to its original site, indicating that the white hair resulted from the surgical procedure rather than environmental factors. These findings contrast with previous research on guinea pigs, which showed that hair follicles retained their pigment-producing abilities after transplantation.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

community So we have 20k dollars human like machines available but no new effective treatment for hairloss since finasteride :)

community Some more realistic 15 months fin+min results. No loss, but also basically no growth. HT unfortunately seems like the only option left at this point :/
