A deep and magnetic red, rich in warmth and enveloping reflections. Grace Color 7.66 Medium Red Red Natural Blonde gives hair a vibrant, fiery blonde-red hue that captures light with extraordinary brilliance. Imagine the vibrant shade of autumn maple leaves or the velvety red of a fine wine: a sophisticated and bold color, perfect for those who want to stand out. Thanks to its ammonia-free formula, it provides impeccable gray coverage and long-lasting luminosity. The perfect ally for every professional hairstylist, delivering high performance while fully respecting the hair fiber.

Why choose this product: Grace Color 7.66 is the ideal choice for those who want to achieve a vibrant red without compromise. 100% gray coverage, intense and long-lasting pigments, and an ammonia-free formula make this dye perfect for both a full-color transformation and bold, deep highlights.

Enriched with grape seed oil (Vitis Vinifera Seed Oil), it nourishes and protects the hair, preventing the dryness often associated with intense shades. Hydrolyzed keratin helps to rebuild the hair fiber, keeping it strong and shiny. The pigment responsible for the deep and uniform shade is Toluene-2,5-Diamine Sulfate, ensuring long-lasting vibrancy and superior coverage.

If you are looking for a warm and sophisticated red, Grace Color 7.66 is the perfect choice to enhance your personality with a bold and luminous color.

How to achieve the chosen color step by step: To prepare the mixture, blend 50 ml of Grace Color 7.66 with 75 ml of NIKA Grace Activator, choosing the appropriate volume:

• For complete and intense coverage, use 20 volumes (6%) with a processing time of 40-45 minutes.
• For a brighter, more reflective result, opt for 30 volumes (9%) to enhance shine and depth.

On virgin hair, apply the mixture first to mid-lengths and ends, leaving it on for 15 minutes. Then, distribute the color to the roots and leave it for an additional 30 minutes.

On previously colored hair, apply only to the regrowth and let it process for 30 minutes. To even out the color, emulsify it onto the lengths during the last 5-10 minutes.

Emulsification and rinsing: At the end of the processing time, add a small amount of warm water and gently massage the scalp to emulsify the color. This helps remove excess product and enhances the final shine. Rinse thoroughly until the water runs clear, then proceed with a color-safe shampoo to lock in the pigment and extend its vibrancy.

Tips for maintaining the perfect color: To prolong the brilliance and longevity of this intense red shade, follow a targeted hair care routine.

• Use sulfate-free shampoo and conditioner specifically for colored hair to maintain vibrancy.
• Avoid frequent washing: washing 2-3 times a week helps prevent premature fading.
• Protect hair from heat and UV rays with thermal protectant sprays and sun filters.
• Apply hydrating treatments weekly, such as oil-based masks, to keep the color radiant and the hair soft and healthy.
