McDonald’s fries might be bad for your health, but there’s a chance they’ll put hair on your head.
In a study published in the journal Biomaterials, a stem cell research team at Yokohama National University developed a method that could lead to a new treatment for hair loss.
Dimethylpolysiloxane, which Newseek reports is a silicone added to McDonald’s fries to stop cooking oil from frothing, was used to regrow hair on mice.
Early tests showed that the “simple” method used was likely to be just as successful when tested on human skin cells. Scientists were able to successfully mass-produce “hair follicle germs” (HFG) for the first time ever in this manner.
HFGs are the cells that drive follicle development and they’re the key to hair-loss research.
Professor Junji Fukunda wrote in the study that 5000 HFGs were successfully prepared simultaneously, leading to new hair growth after they were transplanted onto the bodies of mice with a chip.
“The key for the mass production of HFGs was a choice of substrate materials for the culture vessel,” Fukuda said in the study. “We used oxygen-permeable dimethylpolysiloxane (PDMS) at the bottom of culture vessel, and it worked very well.”
Fukuda later reported black hairs were found on the parts of the mouse where the chip was placed.
“This simple method is very robust and promising,” Fukuda said. “We hope this technique will improve human hair regenerative therapy to treat hair loss such as androgenic alopecia (male pattern baldness).”
