You can safely go darker with Single Process Color in a single appointment. Lightening is limited — lifting several levels often requires lightener or balayage techniques. We’ll assess your hair to recommend the safest route to achieve your desired shade.

A typical Single Process Color appointment takes about 60–90 minutes, including consultation, color application, processing, and rinse. Time varies with hair length, thickness, and desired result. Longer timing may be needed for additional treatments or complex color corrections.

We recommend a patch test at least 48 hours before your Single Process Color if you have sensitive skin or a history of reactions. It helps identify allergies to color ingredients and ensures a safe service. Walk-ins may be treated at stylist discretion.

Use a sulfate-free, color-safe shampoo and conditioner to prolong Single Process Color. Add a UV protectant, weekly deep-conditioning gloss, and heat protectant before styling. Schedule gloss refreshes every 6–8 weeks to maintain shine and color depth.
