I got a haircut from Christy at Local B about a month ago. Christy was so friendly and chill. I don't know much about hair at all but she immediately understood what I was trying to ask for, despite my giving her very little to go on. I ended up with a great haircut. I'll definitely be back.
The actual salon has a cleanly stylish vibe without being intimidating or too cool for school. Despite the chic staff and atmosphere, the place still feels warm and welcoming. You may be lucky enough to meet the so-cute-it-hurts pomeranian Marni when you visit.
One small friendly suggestion for Local B, that I personally think would make the experience even better: it would be really cool if there were a different way to tip your staff. Maybe it's just me, but it feels a bit awkward handing cash directly to the hairdresser at the end.
