Ive only just turned 24 and ive had a few grey hairs. Ive heard it can be caused by stress.

Ive also heard of people going grey overnight. Like my cousins friend, she reckons he went grey basically overnight after his father died.

Has anyone else heard of this?

Sometimes i find a really long strand of grey, and i think OMG how did i miss that! (cause i tweeze em out) So maybe it turned grey overnight????!!!
