Could an Idaho staple help cure one of your man's most embarrassing traits? Some experts say this actually works.

McDonald's adds the chemical dimethylpolysiloxane to their famous french fries (in the cooking oil). Why is this a big deal? Apparently, that chemical has been shown to help with hair regeneration in lab tests on mice. The person who discovered this breakthrough, Professor Junji Fukuda, says that the chemical can help create thousands of large hair follicle germs. In plain English, it can help regrow hair:

This simple method is very robust and promising. We hope that this technique will improve human hair regenerative therapy to treat hair loss such as androgenic alopecia.

Does this mean feeding your boyfriend lots of McDonald's french fries can cure his baldness? The theory hasn't been tested on humans yet, so why not be their case study? Hit up Mickey D's, slide your boo a supersize fry, and pray to the science gods that he gets those luscious locks back.
