How to check who sells K18 on Amazon

1. Browsing from outside the US, set a US delivery address first; any ZIP will do, 10001 works. Without one Amazon fills the buy box with import and reseller offers. That is how Charlotte Tilbury, Dyson and Clinique once looked unstocked to us, when Amazon.com sold all three.
2. Read the two lines beside Add to Cart, “Ships from” and “Sold by”. For K18 you want K18's own store (“K18 Hair”).
3. If another name is there, open “Other sellers on Amazon”. Amazon.com or the brand sometimes sells the same listing one row down, at the same price or close to it.

   COSRX Peptide 132 Ultra Perfect Hair Bonding Treatment

   for K18 Leave-In Molecular Repair Hair Mask

   $16 against $75, 91% less per ounce ($3.94 / fl oz versus $44.36 / fl oz).

   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, color and heat damage.

   What it 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.
