I don't recall the name but there is a salon in Simpson Bay, Georgina's maybe? In the Palapa Building? But those names are just a guess. It's upstairs in the long dark brown two story building on the left hand side if you're coming from the airport. Several of the women at our timeshare have recommended it to me in the past but I could never manage to tear myself away from the beach long enough to get a fill. You might also check with the Good Life Spa or the spa at the Cliff.
