What It Is

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

While No.1 (sold separately) is added to color, lightener, and chemical services, No.2 is the post-color/chemical service step to target bonds that may have been missed by No.1.

It rebuilds all three bonds, including disulfide bonds, to leave hair stronger, softer, more manageable hair in just 3 minutes at the bowl before shampooing. 

What It Does

• Reverses damage in 3 minutes after color, lightening, and chemical services
• 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

• Cut breakage in half during color or lightening services.*
• 75% End to End Bond Repair vs. Bleach Alone** 
• Repairs and Protects Hair From The Inside Out In One Salon Session
• 3-Minute Damage Repair***
            

*Result of using No.2 after processing No.1 mixed with lightener. 

**Based on clinical testing done on curly hair when used as a system with N°.1

***When used as a system with N°.1

1. No.1 Bond Multiplier®: 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 No.1.

Rated 5 out of 5 by from Amazing Treatment This treatment always helps revive my waves. I have mixed texture with waves and curls that fall easily and this also helps the texture become more even throughout. It’s a shame they got rid of the larger size.

Rated 4 out of 5 by from Still OK I still trust Olaplex, but miss the larger bottle. Not sure why they downsized.
