Hair Transplantation Between Identical Twins

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.

The user is considering another hair transplant or scalp micropigmentation (SMP) for a congenital bald spot, but previous transplants were less effective due to scar tissue. Suggestions include using hair fibers, changing hairstyles, or doing nothing, as the spot is not very noticeable.

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.

Longitudinal partial follicular unit transplantation involves extracting part of the donor follicular unit, allowing the donor area to maintain hair production and potentially increasing transplant yield. The conversation questions if this method is practiced in clinics or remains theoretical, and whether it relates to hair cloning or multiplication.

Hair transplants typically involve spreading follicle extraction across the back and sides of the head to maintain an even appearance, rather than taking a solid rectangle of grafts. FUT procedures, which involve taking a strip of skin, are less common now due to advancements in techniques like FUE, which heal well and are less invasive.

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.
