Ivy Spa Club in downtown Minneapolis is adding a full service hair salon. They're currently recruiting stylists and plan to open by mid-February. Because the salon will be part of the spa, customers can turn a haircut into a mini-retreat, using Ivy's fitness center, relaxation areas and whirlpool - heck, even the bathrooms feel like a vacation. I'm thinking this makes a lot of sense for Ivy, especially given its hotel setting. Stay tuned for more details.
