Frequently Asked Questions
How to use Olaplex No.3?
Apply a generous amount to damp, towel-dried hair from roots to ends. Leave on for a minimum of 10 minutes (up to 90 minutes for deeper repair). Then rinse and follow with shampoo and conditioner. Use once a week for best results, or more often for severely damaged hair.
What does Olaplex No.3 do?
Olaplex No.3 is a bond-building treatment that repairs broken disulfide bonds inside your hair caused by chemical treatments, heat styling, and environmental damage. It restores strength, structure, and elasticity from within — making hair visibly healthier, shinier, and more resilient.
What is Olaplex No.3?
Olaplex No.3 Hair Perfector is an at-home pre-shampoo treatment (not a conditioner). It contains the patented ingredient Bis-Aminopropyl Diglycol Dimaleate that works on a molecular level to find and repair broken bonds in hair. It is the #1 bestselling Olaplex product worldwide.
How long can you leave Olaplex No.3 in your hair?
The minimum recommended time is 10 minutes, but you can leave it on for up to 90 minutes for more intensive repair. Some users even sleep with it overnight under a shower cap for maximum bond repair on very damaged hair. There is no risk of over-processing — the treatment simply stops working once all accessible bonds are repaired.
