Hair Color Additives & Fillers

Achieve more predictable results with professional hair color additives and fillers designed for tone control, porosity management, and longer-lasting vibrancy. This curated assortment brings together targeted add-ins commonly used alongside permanent hair colour, demi-permanent colour, and hair bleach services to help deliver cleaner, more even outcomes—especially on lightened hair, grey hair, or highly porous strands.

In many colour correction routines, additives and fillers help balance the hair canvas before you apply your final shade. They can support more uniform deposit, reduce patchiness caused by uneven absorption, and refine undertones such as warmth, brass, or ash. Whether you’re refreshing faded mids and ends, rebuilding pigment before going darker, or preparing for a richer brunette or red, these tools help improve consistency and finish.

What these formulas can support

• Filling missing pigment for smoother brunette and red results
• Porosity control after highlights, lifting, or bleaching
• Undertone correction for brass neutralization and tone refinement
• Richer-looking deposit to support grey coverage appearance
• Improved feel and slip during colour services

Choosing the right additive or filler

Select based on your starting level, desired shade family, and the underlying pigment you need to rebuild. For best precision, pair with hair color mixing bowls and measure ratios carefully for consistent processing.
