What matches

Same job: a sulfate-free purple shampoo whose violet dye cancels the yellow and orange in blonde, grey and lightened hair.

What the dupe does worse

Olaplex adds its patented bis-aminopropyl diglycol dimaleate and cleans with an olefin sulfonate, while L'Oréal uses isethionate and sulfosuccinate cleansers plus amodimethicone for slip, with no bond builder.
