SECONDARY USES

1. Pre-Coloration Treatment: Apply as a preparatory step 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.
2. Toning Services: Use with INOA shades to neutralize unwanted undertones and refresh existing color on lengths and ends. For the person who wants to maintain cool, neutral, or ash tones between salon visits, this provides a targeted correction service.
3. Grey Coverage Enhancement: While 10 volume is primarily for darkening and same-level coloring, it can be used on fine or less resistant white hair for subtle grey blending. For the person with minimal grey coverage needs who wants natural-looking results, this provides a gentle option.
4. Root Touch-Up Applications: Use with matching INOA shade for precise root retouch services where no lift is required on previously colored hair. For the person whose roots have grown out and need refreshing, this provides a seamless match to existing color.
5. Travel-Friendly Salon Backup: The 1L professional bottle is designed for salon use, offering a reliable supply of developer for daily color services. For salons with high-volume color departments, this means never running out of essential product.
