Balmain Professionnel Couleurs Couture Permanent Hair Color in shade 4.5 Mahogany Brown is a professional hair color solution for long-lasting color results. This 60 ml formulation delivers rich, multidimensional mahogany brown tones with permanent color retention. The product features an ammonia-based formula that provides complete gray coverage while maintaining hair structure with nourishing components. Suitable for salon use or experienced at-home application, it offers predictable color development with consistent results across various hair types. The mahogany brown shade combines warm reddish-brown undertones with deep brown as the base color, creating a multidimensional hue with a naturally appearing depth. Application requires mixing with developer in the correct ratios for optimal performance. The typical processing time is 30-45 minutes, depending on the desired color intensity and hair condition. The permanent formula ensures that the color remains vibrant over multiple washes, with gradual fading rather than abrupt color change. The packaging includes precise measurement scales for accurate mixing. The product is formulated to minimize damage through balanced pH levels and integrated care substances. Color results may vary based on natural hair color, previous treatments, and application technique. For best results, a strand test is recommended before full application. The compact 60 ml size is suitable for touch-ups at the roots or complete color applications on shorter hair lengths. Store in a cool, dry place, avoiding direct sunlight. Clean application tools thoroughly after use. The professional formulation meets salon standards for color consistency and performance reliability.
