SECONDARY USES

1. Root Touch-Up on Golden Copper Blonde Hair: Apply only to regrowth area where natural hair needs to be recolored to match previously colored lengths, using 20 volume oxidant and processing for 35 minutes. For the person maintaining their vibrant golden copper color between full applications, this provides a precise root touch-up solution that keeps color consistent and even.
2. Global Application on Virgin Hair: Apply evenly to dry, unwashed virgin hair for an all-over golden copper blonde transformation, starting with lengths and ends for 10-15 minutes before applying to roots, then processing for an additional 20 minutes. For the person wanting to achieve a warm, radiant golden copper blonde from natural hair, this provides the ideal single-process solution.
3. Warmth Enhancement for Dull Blonde: Apply to blonde hair that has become dull or ashy to restore warm golden-copper reflects and add vibrancy and dimension. For the person whose warm blonde has lost its radiance, this provides a refresh that brings back vibrant golden-copper tones.
4. Lengths and Ends Refresh: For a quick refresh of mid-lengths and ends on previously colored hair, if only slightly faded, take through 5 minutes before end of development; if completely faded, add 10-15ml warm water to remaining mixture and take through immediately. For the person whose ends have faded faster than their roots, this provides a seamless refresh that extends the life of their color.
5. Partial Coloring Technique: Suitable for both complete full-head coloring and partial coloring services, allowing versatility in application based on the client’s specific needs. For the person needing targeted color application, this provides flexibility for custom color services.
