Researchers have developed a method using 3D printing to create a mold that mimics the natural environment of human hair cells. This involves engineering human skin to grow around the mold and seeding it with hair follicle cells. The process is enhanced by a cocktail of growth factors, including JAK inhibitors, which stimulate hair growth by reactivating dormant hair follicles. This technique shows promise for hair restoration surgery, allowing for the creation of a grid of engineered hairs that can be transplanted back into the patient's scalp.
