McDonald's (MCD) french fries include an ingredient that could pave the way toward a cure for baldness. But that doesn't mean those concerned about receding hair lines should make a run to the Golden Arches.
Researchers at Japan's Yokohama National University found that a chemical McDonald's uses in its fries can be used as a base to grow hair follicles on mice.
In a news release, the scientists said a formula using oxygen-permeable dimethylpolysiloxane helped them grow hair on the backs and scalps of rodents.
The findings, published in the peer-reviewed journal Biomaterials, involved using dimethylpolysiloxane in a formula to ready 5,000 hair follicle germs, which "were shown to be capable of efficient hair-follicle and shaft generation upon intracutaneous transplantation into the backs of nude mice."
In other words, the chemical helped the process, but in and of itself did not spark a growth spurt of hair.
