It was blonde for the first eight or nine years, then it was a rather nondescripit dull brown through my teens and twenties, but I used to say "it looks slightly red in a certain light." Not that anyone believed it, until recently. Now my hair's definitely burnishing or oxidising to a rather unusual dark copper colour - the kind of shade that almost looks like it's had some assistance. I like it - and hope it continues to oxidise.
At any rate - it'll be nice to finally have a proper hair colour.
