A typical Global Color appointment lasts 60–120 minutes, depending on hair length, density and condition. Consultations and processing time vary; your stylist will confirm timing when assessing hair and desired shade to ensure optimal results.

Yes. Our Global Color technique is formulated to fully cover gray, blending roots through ends for an even, natural appearance. Complete coverage depends on gray percentage and hair porosity; your stylist recommends best formula for reliable coverage.

Absolutely. Global Color can lift or darken your natural shade within a limited range. For dramatic color shifts or major lightening, your stylist may suggest alternative services like highlights or lightening to achieve desired results safely.

You can usually wait 48 hours before shampooing, though many stylists recommend waiting 24–48 hours to allow initial color set. Use color-safe shampoos, lukewarm water, and avoid heavy washing or hot tools immediately to prolong vibrancy.

With proper care and professional formulation, Global Color typically lasts 4–8 weeks before noticeable fading. Longevity depends on hair porosity, sun exposure, and shampooing frequency; we recommend color-safe products and scheduled root touch-ups for consistency.

If you have a history of sensitivities, we recommend a patch test 48–72 hours prior. Though not always mandatory, tests help prevent allergic reactions and ensure safe application. Your stylist can advise if a test is necessary during consultation.
