The 6-volume developer provides soft color deposit for natural, more transparent results ideal for blondes; 9-volume delivers standard tone-on-tone results for brunettes. Development time ranges from 2 to 20 minutes depending on desired outcome .
-

6. Milky Cream Texture for Precision Application
-

-
How it helps your hair: For the stylist performing precise color work, this provides a manageable, non-drip formula that enables clean, professional application. For the client, the creamy consistency ensures even coverage and predictable results with minimal mess.
SECONDARY USES
1. Toning After Lightening Services: Apply to pre-lightened or bleached hair to neutralize unwanted yellow or brassy undertones using 6 volume developer, processing for up to 20 minutes. For the person who has just had highlights or balayage and wants a clean, warm finish with golden tones, this provides the perfect toning solution.
2. Refreshing Faded Lengths and Ends: Apply specifically to mid-lengths and ends after a permanent color root touch-up to revive faded color and ensure a seamless match, using 9 volume developer. For the person whose ends have faded faster than their roots, this provides an even, refreshed result without re-coloring the entire head.
3. Glossing Service: Apply to all-over hair for 5-20 minutes to add intense shine, improve manageability, and deposit subtle color reflection without altering the base shade. For the person who wants a “gloss” service between color appointments, this provides a quick, low-commitment shine boost.
4. Corrective Color and Lowlights: Suitable for corrective color applications, pre-coloration, and creating lowlights to add dimension to blonde or highlighted hair. For the person wanting to add depth and contrast to their color without a full-color service, this provides a versatile option for dimensional results.
5. Pre-Coloration Treatment: Apply before permanent color to even out porosity and improve color absorption on porous ends. For the person whose color turns out darker on the ends than at the roots, this provides a preparatory step that creates a more uniform canvas.
