A hair-raising trick may lead to better hair transplants. Engineered hair follicles patched into skin can be coaxed to connect to surrounding tissue and to grow hair in an organized way, a study in mice finds.

Unlike current hair transplant methods, which simply move existing hair follicles from one area of the scalp to another to cover a bald region, the approach would spur the creation of new hair follicles from existing cells.
“It’s exciting because it shows a cell-based approach for treating hair loss is maybe feasible,” says George Cotsarelis, a dermatologist at the University of Pennsylvania in Philadelphia.
