Plucking multiple hairs close together may actually promote hair growth

study done on mice at the University of Southern California found that tweezing hairs that grow closely together in a small, densely packed location may actually promote new hair growth.

Plucking hairs that were located far away from each other didn’t produce the same effect.

The researchers determined that hair follicles located close to each other can orchestrate a unified response to the injury and inflammation caused by tweezing.

This response is known as quorum sensing. The plucked, distressed follicles secreted CCL2, a chemical that generates a white blood cell response. This generated regrowth in the plucked hairs, plus stimulated new hairs to grow.

This study may hold promise as a potential cure for balding.
