So, what’s the difference between Nº.3 and Nº.3PLUS? 

For years, Nº.3 Hair Perfector® has been the gold standard hair repair treatment for damaged hair. Well loved by professionals and consumers, it transformed at-home hair repair by addressing broken bonds at the molecular level. Now, OLAPLEX is building upon that legacy.

Introducing Nº.3PLUS Complete Repair Treatment, a next-generation, bond-building hair treatment designed to repair, protect, and future-proof hair in just 3 minutes. It’s everything you love about Nº.3...only better.

The Legacy: What Made Nº.3 Hair Perfector® Iconic?

Nº.3 Hair Perfector® set a new standard for damaged hair treatment. Powered by OLAPLEX Patented Bond-Building Technology®, it was designed as a pre-wash treatment that:

  • Repaired broken disulfide bonds inside the hair
  • Helped restore strength after chemical services
  • Targeted damage from coloring, bleaching, and heat styling
  • Improved hair health over time with consistent use 

Nº.3 focused mainly on yesterday’s damage and restoring hair from the inside out. But as hair habits, styling frequency, and consumer expectations changed, so did the need for a more complete approach to repair. 

The Upgrade: What is Nº.3PLUS Complete Repair Treatment?

Nº.3PLUS Complete Repair Treatment is the evolution of Nº.3. It goes beyond repair to protect hair and help prevent future damage.

This new formula is designed to support foundational hair health, addressing hair’s full lifecycle: past, present, and future damage.

Past: Repairs all types of hair damage 
Present: Delivers immediate softness, smoothness, and strength
Future: Defends against breakage, split ends, and daily stressors

What’s New with Nº.3PLUS Complete Repair Treatment?

Nº.3PLUS doesn’t just address damage–it supports long-term hair integrity. It moves beyond “repair only” and into complete hair health.  And it works in just 3 minutes.

Here’s how Nº.3PLUS Complete Repair Treatment builds healthier, stronger hair:

  • Repairs hair in just 3 minutes, restoring strength and softness quickly
  • 3x stronger hair, reinforcing the cortex to reduce breakage over time
  • 3x softer hair, instantly improving smoothness and manageability
  • 360° cuticle-to-cortex repair focused on all 3 hair bonds, strengthening the hair from the inside out
  • Improved length retention for all hair types, helping hair grow longer by preventing future damage from heat, color, and mechanical stress
