My daughter Katie recently regaled me with details of Drybar, a salon in which you can get only one service: a perfect “blowout” for your hair—along with the attendant experiences that help you prepare for a special night out and make you feel good about yourself while you’re there. (I had no idea such things were coveted, but I stand duly corrected.) In just a few years, Drybar has become a visible success in cities around the country.
