There s hope for (us) people suffering from hair loss. A new study from scientists at the University of Southern California, University of California, and others, found that plucking some hair may induce more hair to grow.
The new research was based on the successful plucking and regrowing of hairs of a mouse. One of the authors of the new study, Professor Cheng-Ming Chuong of USC, said in a press release that they have successfully induced up to 1,200 new hairs after plucking 200 hairs in a mouse.
But don t pluck your hair just yet. The research is about how to attract certain cells that will literally call for follicles to grow more hair by plucking. But methods involve a particular pattern, and specific density.
Prof. Cheng-Ming Chuong said they plucked 200 hair follicles of a mouse, one by one. They found that no hairs will regenerate when hairs were plucked in a low-density pattern exceeding six millimeters in diameter. But after plucking mouse hairs from circular areas with diameters between three and five millimeters, the mouse s skin reacted and triggered a regeneration of 450 to around 1,300 hairs including portions outside of the plucked areas.
Could this discovery lead to biological treatment of men baldness? Maybe. But this study is not just about growing more hair, or finding more effective treatments for human baldness or extensive loss of hairs. It also underlines the fact that mammal cells communicate with one another, just like bacterias.
Through molecular analyses, researchers found that upon plucking of hairs, follicles secrete CCL2, a cytokine, or small proteins. CCL2 will then recruit macrophages, a type of white blood cell, to the whole plucked region.
These cells will then signal Tumor necrosis factor alpha, or TNF-α which will communicate to both plucked and not plucked follicles, and tell them to start growing hair.
The research is entitled Organ-Level Quorum Sensing Directs Regeneration in Hair Stem Cell Populations and was published Thursday in peer reviewed journal Cell with first author Chih-Chiang Chen from the Department of Pathology of the University of Southern California.
