There has been a common conception that plucking out of hairs is not good for their health. However, a new study offers an entirely different story.
According to the scientists, selectively plucking of hair that is in very close proximity can help in stimulating its dense re-growth.
For the study, the researchers involved a mouse and plucked its 200 hairs in a specific pattern and density. It was found that the researchers can induce roughly 1,200 replacement hairs to grow in a mouse.
Cheng-Ming Chuong, a researcher from the University of Southern California (USC), said, “It is a good example of how basic research can lead to a work with potential translational value. The work leads to potential new targets for treating alopecia, a form of hair loss.”
The study commenced a couple of years ago when Chih-Chiang Chen, visiting scholar and study’s first author, arrived at the USC from Veterans General Hospital, Taiwan and National Yang-Ming University.
Chen, who is a dermatologist, very well knew that the hair follicle injury affects its adjoining environment. Moreover, Chuong lab had already proved that such an environment can influence hair regeneration.
To ascertain this concept, Chen worked on an elegant strategy and plucked as many as 200 hair follicles one by one in various configurations on the mouse’s back.
The higher-density plucking in the circular areas with diameters ranging three to five millimeters, the regeneration of hairs was between 450 and 1,300, including those outside of the plucked region.
