They say blondes have more fun, but I really like it when it's taken up a notch by going slightly grey or silver. It's a work in progress for me because I did not bleach my hair completely at first (just a full set of highlights) and rather take the time than turning violet... or bald.
At the moment it's a blonde/ashy tone, with silver streaks when the sun hits my hair. But for the Summer I am aiming for a white-blonde shade. Good thing I don't really tan ;-)
