Olaplex Nº.0 Intensive Bond Building Hair Treatment - Priming Treatment, 155 mL

Amplify your hair repair results with Olaplex Nº.0 Intensive Bond Building Hair Treatment – a professional-inspired primer that prepares hair to absorb the maximum benefits of No.3 Hair Perfector for visibly healthier, stronger hair.

Key Benefits:

• Primes Hair: Prepares hair to receive deeper bond-building repair when used before No.3
• Strengthens Bonds: Rebuilds broken disulfide bonds for stronger, more resilient hair
• Boosts Repair: Increases repair results by up to 68% when used as part of the Nº.0 + No.3 system
• Repairs Damage: Targets damage from chemical treatments, heat styling, and environmental stress
• Protects Hair: Shields hair from future damage while restoring health and vitality
• Universal Formula: Works on all hair types – coily, curly, wavy, and straight

How It Works:

Powered by Olaplex's highest concentration of patented bond-building technology, Nº.0 acts as an intensive primer that opens the hair cuticle and saturates strands with active ingredients. When followed by No.3 Hair Perfector, it delivers professional-level repair results at home.

Perfect For:

Anyone with severely damaged, over-processed, or fragile hair seeking maximum repair and strengthening. Ideal for colour-treated, bleached, chemically processed, or heat-damaged hair that needs intensive restoration.

How to Use:

Apply Nº.0 to dry hair, saturating from roots to ends. Do not rinse. Follow immediately with No.3 Hair Perfector, applying generously over Nº.0. Leave on for a minimum of 10 minutes (or up to 90 minutes for deeper repair). Rinse thoroughly, then shampoo and condition with Olaplex Nº.4 and Nº.5. Use 1-2 times per week for best results.
