Choose Between Two Options

Stylists slather tresses with Salon Tech's keratin-rich concoctions. Once the hair is dry, they activate the ingredients by passing locks through a flat iron heated to 450 degrees Fahrenheit. Alternatively, they use Milbon Japanese hair-straightening products, along with flat irons, to chemically change the structure of the hair from curly to completely straight.

Hair OSH

The curved metal sign outside Hair OSH stands in stark contrast to the surrounding buildings, which are made of brick and engraved stone. But behind this modern façade, the 3,000-square-foot interior takes on a more organic tone. Planks of wood and earth-toned tiles line the walls and surround minimalist furnishings. They also shelter a team of specialists who draw on a decade's worth of hair-straightening knowledge accumulated from Japan and Korea. Rather than cater to a wider audience, they focus their efforts on curly 'dos assailed by frizz, tangles, and nesting birds.
