MATRIX SoColor Sync Pre-Bonded ammonia-free demi-permanent hair colour 6NGA, 90 ml

MATRIX SoColor Sync Pre-Bonded 6NGA is designed for tone-on-tone colouring when the lengths have lost tonal definition or no longer match the roots. A coordinated formula refreshes mid-lengths, refines transitions and restores shine without using the same permanent colour mixture throughout.

Taurine and cationic polymers form a built-in hair bond-protection system. It helps protect internal hair structure during repeated colouring, while the conditioning ammonia-free base leaves hair looking smoother and shinier. Its coordination with the SoColor palette is useful when roots and lengths have different needs.

After repeated colouring, the lengths often need refreshing to match the root shade. A tone-on-tone formula creates a soft transition and restores colour vibrancy with an approach suited to the mid-lengths and ends.

MATRIX SoColor Sync Pre-Bonded 6NGA is a demi-permanent hair colour for precise colouring and creating the desired shade.

The alkaline SoColor Sync series refreshes colour and harmonises tonal transitions. Its shades are coordinated with the SoColor permanent colour palette so the stylist can select different formulas for roots and lengths within one service.

Who is this hair colour suitable for?

For professional use with shade 6NGA. Before colouring, assess the starting base, previous treatments and porosity. The final tone depends on the starting hair colour and application technique.

How to use

Mix 1:1 with SoColor Sync Activator 2.7% (9 Vol). Apply to dry hair or hair that is approximately 80% dry. Monitor visually and process for up to 20 minutes. Rinse thoroughly. Wear suitable gloves and follow the instructions for the specific colour pack, including allergy testing.

Practical application guidance

• Before adding activator, choose a formula suited to the existing colour of the mid-lengths and ends. The permanent root colour number alone does not determine the intensity needed on porous ends.
• Apply throughout the lengths, only in the transition area at the roots or to individual strands. Ensure even coverage in each area and monitor tone development visually for the specified time of up to 20 minutes.
• For example, mix 45 g of colour with 45 ml of the 2.7% activator specified for this SoColor Sync version. Apply evenly to the selected areas and monitor tone development for up to 20 minutes.
• For repeat colouring, select the mid-lengths and ends formula according to porosity and existing tone rather than automatically reusing the permanent root colour mixture.

Key ingredients and their roles

• Taurine and cationic polymers — components of the built-in bond-protection complex for internal hair structure protection.

Product story

SoColor Sync is based on consistent colour from roots to ends. Different areas may need different approaches in one service: the base colour changes at the roots, while existing colour is refreshed through the lengths. The series' tone-on-tone formulas are coordinated with the SoColor permanent palette so these steps can be combined in a carefully planned professional service.

Pre-Bonded technology complements toning with internal structure protection. The ammonia-free formula adds colour and a soft, conditioned feel, while the wide shade range supports cool and warm accents. This lets the stylist choose tone to suit the starting base and intended transition, maintaining a coordinated result throughout. SoColor Sync fulfils this colour-harmonising and refreshing role.
