Fiber implantation for pattern baldness.

Examination of 20 patients who had fiber implantation for the treatment of pattern baldness showed that nearly all the fibers had fallen out by ten weeks. Complications observed were facial swelling, infection, foreign-body granulomas, scarring, and permanent hair loss. Scanning electron microscopy identified the fibers as modacrylic fibers. The complications, high monetary cost, and ultimate futility of fiber implantation make it an unacceptable procedure.
