Olaplex No.0 Bond Builder

Olaplex No.0 Intensive Bond Building Treatment is a professional-inspired pre-treatment that primes hair for deeper repair, delivering the highest dose of patented Olaplex technology found in any take-home product. It strengthens hair and repairs damage on a molecular level by rebuilding the disulfide bonds that give hair its structure, addressing damage caused by chemical, thermal, mechanical and environmental stressors. It is colour-safe, vegan and suitable for chemically treated hair, and is formulated without sulphates, silicones, phthalates, phosphates, parabens, MIT/MCI or protein.

No.0 Intensive Bond Building Treatment is not recommended for use by itself — it is designed to work as a repair "booster" alongside No.3 Hair Perfector, with studies showing 68% more repair in just one use when used as a three-part system of No.0, No.3 and No.4. Apply to dry hair in sections from roots to ends; hair does not need to be saturated, rather the product should be evenly distributed, like a primer. It is recommended for use before and after colouring the hair for maximum strengthening and repair, and does not need to be applied to clean hair, though this can be used at your discretion if there is product build-up.

• Phenoxyethanol — a widely used cosmetic preservative that helps maintain the stability and shelf life of the formula
• Sodium Benzoate — a preservative that works alongside Phenoxyethanol to protect the formula from microbial contamination
