Chinese scientists have built Detangle, a comb designed to treat hair loss simply while you brush. In experiments on mice, fur grew back over almost all of the bare skin within 28 days.
This was reported by Cherie FM.
The results were published on 3 November in Nature Communications. Eighteen researchers from Beihang University in Beijing, City University of Hong Kong and other institutions worked on the study.
The comb targets androgenetic alopecia, which gradually thins the hair of both men and women. Its teeth hide electrodes and capsules of medicine: as you brush, an electric field stimulates the hair follicles and carries the drug deep into the skin.
The device was tested on mice in which hair loss had been induced with testosterone. Those brushed with Detangle were almost fully covered with fur again, while mice given the popular treatment minoxidil every day regrew about 70%.
The comb was named after the Disney film Tangled, and the English word detangle means to untangle.
However, Detangle has not yet been tested on people. Further research will have to show whether it is safe for human skin and how long the effect lasts.
