Fast Food Additive Could Help Regrow Hair, Study Says

'I'm loving it' is a common reaction people have after learning a fast food favorite uses a chemical that a Japanese study found could help with baldness.

Doctors say the discovery could be a game-changer in the way hair is grown.


Several McDonald's menu items, including the french fries, contain a chemical that Japanese researchers used to successfully treat hair loss in mice.

"When I first heard about it on the news this morning, it gave me something to think about," said Henderson Gee.

Gee is a McDonald's regular, going in about four times each week to order his usual "McDouble, fries, and a sweet tea."

With confusing headlines abound, many have the idea that eating the famed fries can help regrow hair; however, that's not the case.

In reality, it's a silicone chemical used in the oil at McDonald's called Dimethylpolysiloxane, which is FDA-approved for use in the food industry as a defoaming agent.

"I don't know why they would put silicone on french fries," said Dr. Carl Shory, a Birmingham doctor who runs a hair clinic.

Japanese scientists say they've found a way to use it to make a matrix, or environment, for hair follicle growth.

Explaining the process, Dr. Shory says the cells absorb oxygen and nutrients in the gel matrix before being transplanted onto mice.

The researchers called the experiment "a promising strategy for improving current hair-regenerative medicine techniques."

So, fries anyone?
