Studio No. 4

Studio No. 4 is a Boston hair salon at 129 Newbury Street, Suite 406, founded by four stylists. According to the salon, it is a destination where beauty and luxury come together.

Services are grouped into Color, Styling and Extensions. The color menu includes full and partial foil, Sunburst foil with around 20 foils around the crown for a sun-kissed effect, single-process color to cover gray or change shade, glazes that add shine and tonal depth, and Base Break, which lightens the roots for a gradual transition and includes a glaze. Color correction for previous coloring mistakes is priced after consultation. Styling covers haircuts, cut and blow dry, and House Call appointments where cutting and blow dries take place at the client's location, starting at $250 per person. Extensions begin with a consultation, with Bonded and Tape-In options that add length, volume and fullness using natural hair attached to existing hair.

The salon says it uses only the products and techniques it considers the best. Prices and durations are starting-point quotes, and prices for color correction and extensions depend on consultation.
