In Vivo Follicular Unit Multiplication: Is It Possible to Harvest an Unlimited Donor Supply?

Longitudinal partial follicular unit transplantation involves extracting part of the donor follicular unit, allowing the donor area to be overharvested without noticeable hair loss. The conversation questions if this method is practiced in clinics or if it's theoretical, and whether it relates to hair cloning or multiplication.

Chinese researchers have successfully created hair follicles in vitro, potentially offering unlimited hair for transplantation and a cure for hair loss. They plan to test these follicles in vivo on human scalps.

Hair/scalp cloning for unlimited transplants is likely a decade away, with prior transplants not significantly affecting future options. Advances in AI and research in wound-induced hair neogenesis are promising, but infrastructure and technology constraints remain challenges.

A breakthrough in hair follicle cultivation using induced pluripotent stem cells (iPSCs) has been achieved, producing large hair follicles suitable for transplantation. Clinical trials for this hair multiplication technology are planned in partnership with Yinguan Biotechnology.

The conversation discusses the potential cost of hair transplants if verteporfin allows for an unlimited donor area, suggesting that prices could vary based on the number of grafts needed. The user speculates that costs could be calculated per graft or a set amount for a specific number of grafts.

Stem-cell hair transplants could potentially create thousands of grafts from a single donor graft, offering a solution for hair loss with DHT-resistant hair. Companies like Stemson Therapeutics and OrganTech are working on this technology, which may become available in the future, possibly reducing the cost and making it widely accessible.
