Prosthetic Follicles?

Do you have any knowledge or opinion about prosthetic follicles? I was imagining a tiny hypo- or non-allergenic device of plastic, silicone, etc that could even eject broken hairs and be reloaded. If they can replace heart valves and if they can make silicon wafers with microscopic transistors, artificial follicles hardly seems unfeasible. I googled my idea and actually found something:
A hair prosthesis consisting of allogeneic hair and polypropylene mimicking follicular units: long-term result and histocompatibility in rabbits

This sounds wonderful for balding or bald rabbits. There’s still a lot that needs to be done before it is shown to be safe for humans.
There is reasonable experience in artificial hairs and the history is not pretty, with infections that really mess up the scalp. I have personally seen the results of artificial hair over the years and have removed them in patients I’ve seen, but the problems never seem to clear. They look good when they are initially done, but hopefully people will live long enough to regret the decision to do this.
