Cloning Eyebrows?

Is hair cloning only limited to the top of the head or are they also working on cloning eyebrows? Hence they grow at the same length and density or are they soley working on head hair because it is of more concern to the majority of people?

When hair cloning is available, it will have a genetic clock that should dictate the hair cycle for each particular hair, hence its length. But saying much about something that is not here now and possibly won’t be available for 10+ years, would be foolish for me at this time. It would be like having a long discussion about flying cars and the speeds at which they travel.
