First off, I have to confess that I’ve always been fascinated with Extreme Makeover, What Not to Wear, and other physical transformation shows. Of course, I know that beauty is not only skin deep and Gabrio Staff was the first to tell me so when I visited his Centro Benessere on the très chic Via dei Tornabuoni. His new centre, he told me, wasn’t just another hair salon. It was a place where beauty was treated from head to toe and from inside out. “Prove it,” I challenged.
