Yes, one of the times I saw it was on one of the 'Top Model' programmes. However, they did it on both blond/fair girls and dark hair/skinned girls. I do think both time was in America but, bearing in mind how world trends filter through - I was interested to hear if anyone had been asked to do it in the salon yet!?
I shall keep my eyes open in the glossies to see if it filters through there too.
