Davines Heart of Glass Intense Treatment is a deep repair mask formulated specifically for blonde and lightened hair. This 5.07 oz product is designed to restore strength and manageability to chemically processed hair while maintaining the desired cool or warm tones of blonde shades. The treatment features a blend of natural ingredients, including sunflower seed extract and lemon extract, which work to protect hair color from fading and reduce the appearance of brassiness. The formula is enriched with nourishing oils and proteins that penetrate the hair shaft to repair damage caused by bleaching, coloring, or heat styling. This mask is suitable for all hair types, particularly those with fine to medium texture, as it provides intensive moisture without weighing hair down. The creamy texture is easily applied and rinsed out, leaving hair feeling soft and smooth. It is free from parabens and sulfates, making it a gentle option for daily or weekly use depending on hair condition. The product is designed for individuals seeking to maintain the vibrancy of their blonde or lightened hair while addressing issues like dryness, breakage, and lack of shine. It is not intended for use on uncolored or very dark hair, as its clarifying properties may alter tone. For best results, apply to clean, damp hair, leave on for five to ten minutes, and rinse thoroughly. This mask is compatible with other Davines Heart of Glass products for a complete haircare routine. The packaging is compact and practical for travel or home storage.
