Frequently Asked Questions

Get answers to common questions about Double Process.

A double process first lifts natural pigment with a lightener, then applies a toner or color to achieve the final shade. The service includes consultation, strand testing, bond-repair treatments as needed, processing time, and a professional finish.

Yes, but suitability depends on prior color history and hair condition. Dark or previously colored hair may require additional sessions or careful lifting to avoid damage. Your stylist will assess and recommend a safe plan with bond repair if necessary.

Appointments usually take between two and four hours depending on hair length, density, desired lift, and processing times. Extra time may be needed for consultations, corrective work, or additional bond-building treatments to preserve hair health.

Because it involves lifting then coloring, a double process can be more stressful to hair. Professional techniques, proper timing, and bond-repair treatments significantly reduce risk, and your stylist will recommend aftercare to maintain strength and minimize breakage.

Come with clean, product-free hair and disclose recent chemical services. Avoid at-home coloring for several weeks. Bring reference photos and be prepared for a consultation; sometimes staged sessions are advised for the healthiest outcome.

Longevity depends on porosity, aftercare, and sun exposure. Expect vibrant results for several weeks, with toning maintenance recommended every 6–8 weeks. Use color-safe formulas, bond-supporting treatments, and sulfate-free products to extend vibrancy.
