Turn Permanent Colour Into a Tone-on-Tone Service

ASP Converter gives professional colourists more flexibility from the permanent colour shades they already stock. When mixed with permanent colour, Converter transforms the formula into a tone-on-tone / demi-permanent colour service, helping salons expand their service menu without carrying a completely separate demi-permanent colour range.

The result is rich, glossy colour deposit with minimal lift—ideal for refreshing, toning, grey blending and lower-commitment colour services.

Why Stylists Love ASP Converter

• Converts permanent colour to tone-on-tone colour by reducing the lifting action of the permanent formula.
• Up to 50% grey coverage for natural-looking blending and beautiful shine.
• 20–25 minute processing time at room temperature with no heat required.
• Wet or dry application allows the stylist to customize the intensity and longevity of the finished result.
• Works with most permanent colour shades, excluding High Lift / 12 Series shades.
• Vegan and sulfate-free formula designed for professional salon use.

More Colour Services — Less Inventory

ASP Converter allows salons to get more from the colour shades already on the shelf. Instead of stocking separate permanent and demi-permanent ranges, stylists can use their existing permanent palette to create additional tone-on-tone services.

Perfect for:

Toning • Glossing • Grey Blending • Colour Refreshes • Mids & Ends • Low-Commitment Colour • Shade Expansion

Clients can also transition easily from a tone-on-tone service to permanent colour while staying within the same shade family.
