There’s something to be said for that whole “destiny” thing. After a stretch in the movie biz, Elan Sassoon (yes, he’s the son of the legendary Vidal) proceeded to forge his own way in the beauty industry, launching a skincare line, running a chain of medi-spas, and developing a suburban spa concept called Green Tangerine. But he truly hit his stride with the practically concurrent openings of two Mizu salon locations: the first in Boston’s swank Mandarin Oriental Hotel this past October and the second only a couple of months later on Park Avenue in New York City. (Beverly Hills is the next market he’ll tackle.) But the thing that most intrigued us? Sassoon, the brains behind the business, doesn’t actually cut hair — though that may change, he’s quick to point out, when he opens up the 90,000-square-foot flagship “beauty academy” he has planned for Comm Ave.
