With hair topiary I may have invented a new style, a new vogue. Time will tell. For a few years I have been working on a series about hair. I wrote a children's story about hair. In A BOOK OF AGES it forms a leitmotif––when Hitler grew his moustache, when Steve Martin went gray, when Darwin grew his beard, when Hemingway's turned white like Santa Claus's. When he was a child Mike Nichols lost all his hair because of a short, acute illness, including his eyebrows; he's had eyebrow toupees throughout adulthood. I do not go into the topic of merkins, but perhaps that is next.
