blue: a complete hair salon

Soothing shades in gray and blue (of course) set the tone at this cool-but-comfortable salon. And color here is indeed the key: Owner Paula Donovan and her diligently trained staff blend cutting-edge systems (Bumble & Bumble is the mainstay) with down-to-earth reality checks. (Few in Lexington want magenta hair, no matter how great it looked in W.) The result is always glamorous—but tasteful—tresses. 10 Muzzey St., Lexington, 781-862-2030.
