What It Does

• Helps protect hair and support bond repair during color, lightening, and chemical processing
• Reduces breakage and leaves hair stronger-feeling, softer, and more manageable
• Integrates into highlights, balayage, global lightening, permanent color, relaxers, and waves
• Supports fiber integrity without changing standard processing time
• Designed to be followed by Nº.2 Bond Perfector® after rinsing

Complete Bond Technology

Powered by OLAPLEX Complete Bond Technology with the patented molecule Bis-Aminopropyl Diglycol Dimaleate, Nº.1 works at the molecular level to support the hair's internal bond network during chemical, thermal, and mechanical stress.

The three pillars of OLAPLEX repair

• Disulfide (covalent) bonds - supports relinking for strength, resilience, and elasticity during color and lightening.
• Hydrogen bonds - supports bond realignment for improved manageability, softness, and shape memory after services.
• Ionic bonds - helps reinforce internal structure for smoother cuticles, reduced porosity, and enhanced shine.

Key Ingredients

Who Is It For?

• Professional stylists performing color, lightening, and chemical services
• Salons wanting consistent in-formula bond support with backbar efficiency (525ml)
• Clients prone to breakage or hair that feels compromised during processing
• Stylists who prefer flexible restocking with the additional 100ml size option

How to Use
