Olaplex No. 3 is the original at-home bond builder—the one that actually repairs broken disulfide bonds inside your hair. It’s not a conditioner and it’s not a protein mask. The patented Bis-Aminopropyl Diglycol Dimaleate molecule reconnects those inner links so your hair feels stronger, smoother, and shinier after every use.
There’s a common myth that Olaplex “adds protein.” It doesn’t. There’s zero protein here—just chemistry that repairs from the inside out. Once your bonds are rebuilt, finish the ritual with a favorite moisture or protein mask to balance everything out.
The Bonus Size (8.5 oz) gives you more of the good stuff so you can keep your strands thriving through every season.
