Best Olaplex Dupes

Olaplex became a phenomenon with its patented bis-aminopropyl diglycol dimaleate molecule that repairs broken disulfide bonds in hair. The full system ($28-$30 per product) can cost $150+ for a complete routine. While no dupe has the exact same patented molecule, several brands (K18, Boldify, Curlsmith) use similar bond-building technologies that deliver comparable strengthening results.
