L'Oréal is working on the tech with a French bioprinting firm 

The 3D printed hair follicles could be used to grow new hair

If perfected, the process could eventually be much cheaper and faster than hair transplants 

A new 3D printing technique could finally result in a cure for baldness.

While hair transplants, such as those had by England footballer Wayne Rooney, are possible, they involving a painstakingly long and expensive process.

New technology being developed by L'Oréal could lead to 3D printing of new hair follicles that are capable of sprouting new hair.
