(CNN) -- French fries may not be good for your waistline, but your hairline is a whole different story.
Japanese scientists say they've found a new treatment for hair loss...using the same chemical that many fast food restaurants use to cook french fries.
It's a type of silicon that's used to prevent the oil from frothing.
Scientists say that silicon helped create "hair follicle germs" --- a key ingredient in hair growth.
Right now, they're only testing the use in mice, but early research suggests -- the same method will be just as successful when it's used on people.
