Is it possible to fill in a scar on my eyebrow with the hairs from my other eyebrow? If so, would it be a good idea to pluck and collect hairs from my good eyebrow to transplant them later?
Plucking and collecting the hairs for future transplant is not going to work! When we harvest the donor grafts, we are taking the full follicular unit, something that can not be accomplished with plucking. For eyebrows, we generally take the donor hair from the permanent zone in the back of your head, being careful to match the characteristics of your eyebrow hair. If they do not match, then there may be other options. You would need to trim the donated hair, unless you like the unruly look and want ever growing eyebrows with an unusual look. If you let it grow out, it might grow to pony-tail length, so cutting them is important!
There is presently no proof, contrary to claims by some doctors, that a hair that has been plucked will produce a new hair and another hair will grow from the bed of the plucked hair. That would mean that we could manufacture as many hairs as we need, giving unlimited supplies of hair. We have actually tried it based upon reports by a physician at a medical meeting. The plucked hair did not grow a new hair, but the old plucked bed did re-grow another hair.
