It's an early Christmas miracle for Bruce Willis, Vin Diesel, Patrick Stewart and co: a potential cure for baldness could be on the way.
The Daily Mail UK report that scientists have created "hairy skin" in the lab for the very first time using stem cells from mice.
They were able to grow both upper and lower layers of skin which developed hair follicles and resembles natural hair more closely than any other previous models.
The research, which was conducted at the Indiana University School of Medicine in Indianapolis, originally grew tiny versions of real organs called 'organdies', including a tiny ear that could potentially be used to treat deafness before the scientists had the idea to develop hair follicles as well.
The research was published in Cell Reports, with lead scientist Professor Koehler saying: 'It (the hairy skin) looks like a little ball of pocket lint that floats around in the culture medium. The skin develops as a spherical cyst and then the hair follicles grow outward in all directions - like dandelion seeds.'
Looks like vivacious hair is on the way, folks!
