Right, been doing a bit of research on cloning, so here goes,
It was thought that by injecting the new follicles into the scalp they may reactivate existing hairs, but this is still just a theory and there is no evidence to say this is the case, as of yet.
Hair will not be transplanted but injected into scalp, although they recken at first if you don't have a hairline, the hair there will have to be transplanted in the normal transplanted way to create a realistic hairline.
It is also thought that eventually you will be able to decide what colour you want your hair to be, so if your a Ginger and are sick of being called carrot top you could change your hair colour.
Also it will only take 3 months for the new injected hair follicles to start growing.
