Hair loss is among one of the more serious aesthetic woes men and women deal with, and it鈥檚 more prevalent than many of us might realize: according to the North American Hair Research Society, half of women aged 50 and older will experience some degree of female pattern hair loss. While bald聽can *certainly* be beautiful, scientists just discovered a promising ingredient that could help聽those who are fighting to聽hold onto their hair. And here鈥檚 the kicker: if you鈥檙e one of the millions of Americans who has been to McDonald鈥檚, you鈥檝e probably eaten聽鈥 yes, eaten聽鈥 this ingredient.

Dimethylpolysiloxane聽(a type of silicone) is used as an anti-foaming agent in McDonald鈥檚 fries聽鈥 but it turns out that the stuff could be a golden ticket to regrowing hair!聽Scientists from the聽Yokohama National University discovered that the chemical compound can聽create hair follicles, which can then grow into actual, visible聽strands once it鈥檚 been transferred. The study was conducted on mice, who grew some wiry-looking black hairs within days of follicle transplantation.

While the compound has yet to be tested on humans, the scientists are optimistic that the effects will translate. 鈥淭his simple method is very robust and promising,鈥 study co-author Professor Junji Fukuda noted. 鈥淲e hope that this technique will improve human hair regenerative therapy to treat hair loss such as androgenic alopecia.鈥

While we鈥檙e totally pro french fries, it鈥檚 worth noting that eating more of the crispy golden goodies *probably* won鈥檛 make your hair thicker (sorry, guys!). Nevertheless, we鈥檙e excited to see how this discovery could possibly help millions of people regain their tresses.
