For a successful hair transplant operation, the patient needs healthy hair follicles. But how can completely bald people get them? Scientists from Columbia University have started printing them using a 3D printer.
The first hair transplant operations were performed in the beginning of World War II, on soldiers suffering from burns. Burn victims still make up a large part of the demand for these services. However, it is not always possible to deliver the service, because the patient needs to have some hair left on their body.
It looks like we are closer than ever to solving this problem, as scientists have created a new method that allows them to print hair follicles using a 3D printer. The entire operation is held in a micro-environment that is conducive to cell growth, inside a structure made of biocompatible plastic with multiple conduits with a 0.5 mm diameter. These conduits stimulate follicle growth, which can then be planted on skin cells.
This technology will lead to the creation of follicle farms, allowing many people around the globe to get their luscious locks back.
