Tsubaki is a no-frills Japanese hair salon that feels like the real thing. They’re fast, as the name implies, but the stylists never sacrifice the experience to move people through their chairs. It’s also one of the most affordable places in the city for an authentic Japanese hair straightening treatment. Cuts come in two classes: regular and trim. To qualify for the less-expensive trim rate, you must be getting less than an inch of hair cut off.
