The salon sits at the corner of Fillmore and Union Streets. Its building has a family history: Antone Zietich, great-grandfather of co-founder Jessica Allen, came from Croatia to San Francisco more than a century ago and bought the Fillmore building at age 23. Founders named on the about page are Alexa Nelson and Monique Ginocchio. Since July 2025 the salon has been owned and operated by Jen Betti and Kopal Maheshwari.
The salon says it has more than ten years in San Francisco, around 1,000 happy clients and 15 expert stylists. Each stylist or barber runs an independent business and sets their own prices, so services and prices vary by stylist, and clients are asked to book directly with the person they want. New clients call the salon at 415.374.7026, while existing clients call or text their stylist. Cancellations and reschedules need at least 24 hours' notice, and some stylists charge a cancellation fee.
Every visit can begin with a complimentary consultation to talk through hair goals and which services might fit. Haircuts include a consultation, shampoo and style, and extensive style-out or heat work during a cut costs extra. Brides need a trial appointment and a bridal consultation before the trial run. Tape-in extensions and hand-tied wefts require a consultation and a deposit, and chemical smoothing or straightening requires a consultation first.
Street parking has meters allowing 30 minutes to 4 hours. Nearby garages are Lombard Street Garage at Lombard and Webster and Union Street Plaza Garage at Union and Webster.
The salon says it shapes each service around the client's style and goals, and it aims to use high-quality products and sustainable practices where it can.
A calm, spa-like setting.
