What matches

Same job and same routine slot: citric acid bond builder worked through damp hair before shampoo, left 10 minutes.

What the dupe does worse

The bonding chemistry is citric acid rather than Olaplex's bis-aminopropyl diglycol dimaleate, so very bleached hair may need it weekly rather than fortnightly.
