3D Printing of hair transplants is relatively new, but the potential is huge for patients who may not have enough hair available for other methods. In theory, 3D printing would require a digital map of a person’s scalp in order to determine where the cells and components would need to be placed. Through precision printing, follicles could be printed for implantation using bio-ink. Bio-printing is already being tested, but is not ready for consumers yet.
