Madison Reed Color Bar, an up-and-coming chain of hair salons, is on the way to Congressional Plaza. The shop will open this spring next to the new Barnes & Noble store, selling its own brand of hair color products and offering on-site coloring services for $30 to $60. (What won’t it offer? Haircuts.) This will be the second Montgomery County location for Madison Reed, which arrived in downtown Bethesda last month. Meanwhile, there may be more shakeups ahead on the hair scene: Hair Cuttery and Bubbles will be closing multiple locations in the next few weeks.
