Description
The Kadus Professional Demi-Permanent Hydrogen 4% 1000ml is a mild, ammonia-free hydrogen peroxide specifically formulated for demi-permanent coloring and color deepening without lightening the hair. This 4% (13 vol.) developer slightly opens the hair cuticle, allowing color pigments to penetrate the hair shaft more effectively. The result is a soft, natural, and shiny color that deepens and subtly nuances your natural hair color without causing permanent changes.
This product is ideal for clients starting to gray, who desire subtle coverage and a natural look. Its gentle action also makes it perfect for sensitive or damaged hair that can't tolerate strong oxidation. Thanks to its ammonia-free formula, hair stays in better condition and is less stressed during coloring.
The cream formula blends smoothly with all Kadus demi-permanent color products, is drip-free, and distributes evenly throughout the hair for a consistent, even result. The generous 1000ml salon packaging makes this product ideal for professional hairdressers who regularly perform demi-permanent services.
