Since opening the John Barrett Salon 15 years ago on the penthouse floor of Bergdorf Goodman, the Irish-born Mr. Barrett transformed the once-stuffy landscape of the hair salon into a vibrant, festive scene worthy of a chick-lit bestseller, a Broadway musical, or an over-the-top fashion shoot (all of which have been done).

While he has studiously avoided creating anything that could be called a “signature cut,” Barrett strives to give all his clients the same thing: a clean, warm, modern look that melds the glamour and grace of uptown with the youth and vitality of downtown. It’s the perfect formula, one that allows every woman to express herself easily, naturally and beautifully.

And yes, he does it for men, too.
