What Makes Olaplex No. 3 Different?
While most treatments only coat the surface of your hair, Olaplex goes deeper. Its patented ingredient, Bis-Aminopropyl Diglycol Dimaleate, works at a molecular level to rebuild broken disulfide bonds caused by chemical, thermal, and mechanical damage.
Key Benefits:
Repairs damaged and compromised hair
Strengthens and protects hair structure
Restores healthy appearance and texture
Safe for color-treated hair
How to Use It for Maximum Results
Using Olaplex No. 3 at home is super simple. Here’s the step-by-step:
Apply to damp, towel-dried hair (before shampooing).
Leave on for at least 10 minutes (some users go for 30+ for deeper repair).
Rinse, then shampoo and condition as usual.
Use 1-2 times per week for ongoing damage or once a week for maintenance.
