How to use

1. Blend 50 ml of Grace Color 7.66 with 75 ml of NIKA Grace Activator (1:1.5): 20 vol (6%) for complete intense coverage with a 40-45 minute processing time, or 30 vol (9%) for a brighter, more reflective result.
2. On virgin hair, apply first to the mid-lengths and ends and leave for 15 minutes, then distribute the colour to the roots and process for a further 30 minutes.
3. On previously coloured hair, apply only to the regrowth and process for 30 minutes, then emulsify onto the lengths during the last 5-10 minutes to even out the colour.
4. Add a little warm water, massage gently to emulsify, then rinse until the water runs clear.
5. Finish with a colour-safe shampoo to lock in the pigment and extend its vibrancy.

Results and expectations

A medium blonde with a warm, intense double-red reflection, full 100% grey coverage and a fiery, luminous finish. The ammonia-free formula with hydrolyzed keratin, grape seed oil, argan oil and shea butter is gentle on the fibre and helps keep it soft. As a permanent colour it grows out at the roots: plan a touch-up every 4 to 6 weeks. Washing 2-3 times a week helps prevent premature fading.

What you need with it

Safety and patch test

Carry out an allergy alert test 48 hours before each application. This is an oxidative colour for professional use: for major changes, lightening or colour correction, rely on a qualified colourist. Wear gloves, avoid contact with the eyes and do not apply on an irritated scalp.

FAQ

Is it really ammonia-free?

Yes. Grace Color develops with an ethanolamine alkaliser instead of ammonia, for a gentler service on the scalp while keeping full grey coverage.

Which developer should I use?

Use 20 vol (6%) for complete intense coverage over 40-45 minutes, or 30 vol (9%) for a brighter, more reflective result, mixed 1:1.5 (50 ml colour + 75 ml Activator).
