What It Is

This professional-only repair treatment is the first step of the revolutionary Original Bond Building system offered as a single step so you can restock at your own pace.

No.1 is an easy add-in to any color, lighten, and chemical services to help prevent and repair damage as it happens. No need to change the formulas or measurements of your chemical services.

Unlike built-in bonders, N°.1 seamlessly works at a molecular level in your chemical services to rebuild all three bonds, including disulfide bonds, for stronger, visibly healthier hair. Follow up with No.2 (sold separately) after the service to reinforce repair. 

What It Does

• Immediately repairs damage as you color, lighten, and chemically process
• Protects hair and helps prevent damage from salon services
• Reduces breakage and leaves hair stronger, softer, and more manageable

What Else You Need to Know

• 75% End-to-End Bond Repair vs. Bleach Alone* 
• 41% Less Damage vs. Bleach Alone** 
• Repairs and Protects Hair From The Inside Out In One Salon Session
• 3-Minute Damage Repair***
 

*Based on clinical testing done on curly hair when used as a system with N°.2

**Based on clinical testing done on straight hair

***When used as a system with N°.2.

 

1. No.1 Bond Multiplier®: Use as an easy additive to your color and chemical processes. 
2. No.2 Bond Perfector®: Use at the bowl to repair any bonds that may have been missed during chemical services boosted with N°.1.

Please refer to the included mixing chart for specific ratios and instructions for each service.
