Nini B, a nurse and content creator in Los Angeles, only wanted to lower her hairline a little.
In February, surgeon Robert Drummond transplanted 2,500 grafts from the back of her head to her forehead. Everything was going well until the third week of recovery, when the new hair—and some of the old hair around the operated area—started growing in completely gray. She is naturally brunette and had almost no gray hair before the surgery.

Drummond was as baffled as his patient. In hundreds of transplants, he had never seen anything similar, and neither had his lead technician, with more than 20 years of experience and 5,000 procedures under her belt. The doctor suspects that stress on the scalp may have altered pigment production in the follicles, though he admits there is no clear evidence explaining why it happens. He now plans to document Nini’s case for future studies, while she waits with bangs covering the area to find out whether her original color will return.
