Gray hair pill being developed

There are more questions than answers about a pill being developed to prevent gray hair.

The L'Oreal Cosmetic Company says the idea is still in the research phase.

It would be based on a fruit extract that mimics pigment-producing cells.

In theory it would prevent graying.

But scientists say effects of such a pill would be hard to prove because there's no way of predicting who will eventually go gray.
