Grey hair - prevention?

[PaddyBateman]

Hi,

A question not related to balding, but the other thing everyone has to go through .. Going grey!

At 29 I'm not currently going grey myself, but am curious as to whether there's anything out there to help prevent it for the future?

I have seen plenty of supplements that claim to do it, but the only real thing coming that I've seen is L'oreals "revolutionary" drug that is going through trials right now, and due out in 2015.

Anyone know much about this, and is there anything worth doing now to help prevent it in the longer run?

Thanks.
