What matches
Same job in the routine: a sulfate-free shampoo that follows a bond pre-treatment and keeps bleached or heat-damaged hair from sliding back between treatments.
What the dupe does worse
Where Olaplex builds in its patented bis-aminopropyl diglycol dimaleate, L'Oréal relies on citric acid and amino acids, so it maintains hair rather than claiming to relink broken bonds.
