Olaplex No 4C Bond Maintenance Clarifying Shampoo is a powerful weekly deep-cleansing shampoo specially formulated to remove product buildup, excess oil, pollution, chlorine, and mineral deposits from hard water while restoring hair softness, shine, and colour vibrancy. Powered by Olaplex's patented bond-building technology featuring Bis-Aminopropyl Diglycol Dimaleate, it supports hair strength, repairs everyday damage, and reduces future breakage. Its advanced Broad-Spectrum Clarifying System effectively removes stubborn impurities without excessively stripping natural moisture or compromising colour-treated hair. The formula contains Panthenol to condition and soften hair, Glycerin for moisture retention, and amino acids including Arginine, Glycine, Alanine, and Serine to support hair conditioning and manageability. Its pH-optimized cleansing action lifts the hair cuticle to remove accumulated impurities, preparing hair for subsequent conditioning and repair treatments. Free from sulfates, silicones, parabens, and proteins, this vegan-friendly, colour-safe clarifying shampoo is suitable for all hair types, including chemically treated hair, leaving strands feeling refreshed, smoother, stronger, and healthier-looking.
