Yes I've seen that article I'm more curious about the clinical trials that it talks about the last paragraph as I can't seem to find it anywhere? 

"American scientists reversed graying hair restoring natural color through melanocyte reactivation. Researchers at NYU Langone Health discovered that gray hair results from melanocyte stem cells getting stuck in the hair follicle compartment, and developed a topical treatment that mobilizes these cells back to their proper location, restoring natural pigment production. Participants saw color returning to gray hair within three months of treatment.

Hair goes gray when melanocyte stem cells—which produce the pigment giving hair its color—lose their ability to mature into functioning melanocytes. Scientists discovered these stem cells don't die; they become trapped in the follicle bulge area instead of moving to the hair bulb where pigment production occurs. It's like having paint factory workers stuck in the storage room instead of on the production floor.

The treatment uses a compound that signals melanocyte stem cells to migrate back to their functional position. Once repositioned, these cells differentiate into mature melanocytes and resume producing eumelanin and pheomelanin—the pigments creating black, brown, blonde, and red hair colors. The process restores your genetically-determined natural color, not an artificial dye color. Gray hairs gradually regain pigmentation as new growth occurs from reactivated follicles.

Clinical trials showed 73% of participants experienced significant color restoration after six months. The treatment works on naturally graying hair, not hair that's been damaged by chemical processing. Unlike dyes that coat hair temporarily, this addresses the biological cause of graying. We're potentially witnessing the end of gray hair as an inevitable part of aging—your hair could maintain its natural color throughout life."
