This is a professional-grade, ammonia-free demi-permanent hair dye from the Senseo line by Subrina Professional. It is formulated to deliver a vibrant Bright Copper Pearl Blonde shade while providing exceptional color longevity without the harshness of ammonia. Ideal for refreshing existing color, adding brilliant shine, or achieving subtle tone changes, this hair dye deposits color gently onto the hair shaft. The demi-permanent nature means the color will gradually fade over several weeks, offering a low-commitment way to maintain or experiment with your look. It is suitable for professional salon use or experienced at-home application.
