What matches
Both rebuild broken keratin bonds with a low-molecular-weight peptide — K18Peptide in one, Tripeptide-132 in the other — and both are aimed at bleach, colour and heat damage.
What the dupe does worse
This one is rinsed out after a few minutes instead of left in, and it is silicone-and-oil heavy, so fine hair can be left with a slight film K18 never leaves.
