Are your eyebrows getting patchy? Perhaps you'd like to consider an eyebrow transplant. Or perhaps you wouldn't: In the restoration procedure—which takes two to three hours in a doctor's office—individual hair follicles from the back or side of the head (where they aren't noticeable) are removed and placed into the brow area to re-create whatever density you like, says Washenik. But wait a minute: Why wouldn't the hair grow as long as it would if it were still on your scalp? It does, says Washenik. The transplanted follicles don't know that they've been moved, so you get something like bangs growing from your browbone. To avoid this potentially tragic state of affairs, forget transplants and try an eyebrow pencil or powder. Choose one that's a shade lighter than your haircolor, and with feathery strokes, fill in the patchy areas, says brow expert Sania Vucetaj. Brows grow a little longer as we age; brush them upward and trim.
