Description
Professional Ammonia-Free Permanent Colour – Shine, Comfort, and Luxurious Performance
Imagine opening the tube and immediately feeling the creamy, more pliable texture gliding between your fingers. Permanent colouring takes on another dimension: it mixes instantly, envelops every strand, and transforms application into a safe, quick, and precise gesture. There's no stinging. No harshness. Just a feeling of absolute scalp comfort… as the colour begins to reveal itself.
When working with the hair, you notice the real impact of the oil-powered formula. The ODS technology – exclusive, patented, and 60% present – acts as a catalyst for shine and nourishment. The colour sets uniformly, deeply, and luminously. And when the hair dries? That mirrored reflection appears, capturing light from any angle. A 48% superior shine that doesn't fade after a few washes. It stays. It evolves. It lasts.
For those seeking total grey hair coverage and high-impact ammonia-free colour, this vegan formula becomes an ally. Professionals feel the difference in mixing speed. Clients feel their hair is softer to the touch, more nourished, and easier to comb.
There's always the question: will it last? Yes - the enhanced durability guarantees intense and vibrant shades for much longer, without compromising hair health. It's a ritual that simplifies the process, elevates the result, and meets the demands of those who accept nothing less than excellence in professional ammonia-free colouring.
Colour level: 4.0 Fundamental Deep Brown.
