A chemical used in McDonald’s french fries might be able to cure baldness, USA Today reports.
Japanese scientists at Yokohoma National University discovered that the chemical, dimethylpolysiloxane, allowed hair follicles to grow on lab mice.
Eating the chemical will not prevent baldness. The chemical must be placed near the hair follicle to permit regrowth. Another important distinction is that the chemical may not work on human heads. Studies that work on one species do not automatically work on all species.
