Plucking hairs in a precise pattern can make even more pop up in their place, a US study suggests.<\/p>\n
Playing with the density of hair removed altered how serious an injury the body recognised and in turn how much hair regrew.<\/p>\n
The team managed to regenerate 1,300 hairs by plucking 200, in the study using mice reported in Cell journal.<\/p>\n
Experts said it was “really nice science” but were uncertain if it could lead to a cure for human baldness.<\/p>\n
Half of men have male-pattern baldness by the age of 50.<\/p>\n
The team at the University of Southern California were investigating how hair follicles communicate with each other to decide on the scale of repair job needed.<\/p>\n
Inflammation<\/strong><\/p>\n In a series of experiments they removed 200 hair follicles from a circular patch of skin in mice.<\/p>\n A low-density pluck – removing follicles from a patch 6mm in diameter – led to no regeneration at all.<\/p>\n A medium-density pluck, with 200 removed from a 5mm circle, led to 1,300 new hairs.<\/p>\n A higher-density effort, with the same number of hairs but from a 4mm diameters circle, led to 780 new hairs.<\/p>\n Pulling every hair out led to every hair coming back, but no extra regeneration.<\/p>\n
