Olaplex No.4c Bond Maintenance Clarifying Shampoo & No. 5 Bond Maintenance Conditioner Duo 250ml x 2

OLAPLEX No.4C Bond Maintenance Clarifying Shampoo & No.5 Bond Maintenance Conditioner Duo pairs a deep-cleansing clarifying shampoo with a strengthening conditioner to help reset your hair after product build-up and mineral exposure. The brand’s aim is to refresh and “clear the way for lighter, cleaner hair”, while the conditioner follows through with conditioning for softer, more manageable results. OLAPLEX highlights that the duo is a good wash-day pairing to complete the routine, supporting healthier-looking hair after just one wash.

What makes No.4C special is its broad-spectrum clarifying system, which is designed to remove a wide range of impurities that can damage hair, including surface-level build-up. OLAPLEX also positions No.4C as free from protein, silicones, sulfates, and other specified free-from categories, and notes it is suitable for chemically treated hair and colour-safe. No.5 Bond Maintenance Conditioner then helps to strengthen and condition, with an ingredient list featuring moisturising and conditioning agents.

Notable ingredients and technologies (as listed by OLAPLEX): No.4C uses a “Broad-Spectrum Clarifying System” and includes surfactants such as Sodium Lauroyl Methyl Isethionate and Cocamidopropyl Hydroxysultaine, plus Panthenol. No.5 is formulated with conditioning ingredients including Cetearyl Alcohol and Behentrimonium Chloride, along with Bis-Aminopropyl Diglycol Dimaleate, Hydrolyzed Hyaluronic Acid and Biotin.
