Questions
What is the best K18 dupe?
COSRX Peptide 132 Ultra Perfect Hair Bonding Treatment ($13.32) for the Leave-In Molecular Repair Hair Mask ($75), about 93% less per ounce. 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.
Which K18 products have a dupe?
Leave-In Molecular Repair Hair Mask: COSRX Peptide 132 Ultra Perfect Hair Bonding Treatment, $13.32. Leave-In Molecular Repair Hair Mask: Coco & Eve Hair Repairing Leave-In Treatment, $34.
What brands are like K18 but cheaper?
The cheaper alternatives here come from 2 brands: COSRX, for the Leave-In Molecular Repair Hair Mask; Coco & Eve, for the Leave-In Molecular Repair Hair Mask. Each is matched to the K18 product it stands in for on format, finish or key ingredients, and sold on Amazon by Amazon.com or its own brand.
Is K18 worth it?
That depends on the product. 1 of the 11 K18 products we track has a dupe sold by Amazon.com or the dupe's own brand, at 93% less per ounce. Each comparison names what the cheaper one gives up. The other 10 have no dupe here yet, so for those the original is the only one we can point to.
Which K18 products have no dupe yet?
AirWash Non Aerosol Dry Shampoo Spray, AstroLift Reparative Volume Spray, Molecular Repair Hair Oil, FutureIQ Biomimetic Longevity Hair + Scalp Serum, Damage Shield Color Safe Shampoo, Peptide Prep Detox Shampoo, HeatBounce Conditioning Heat Protection Spray, Damage Shield Protective Conditioner, TripleBright Oxidation Defense Purple Shampoo, Leave-In Repair Hair Mask. FutureIQ Biomimetic Longevity Hair + Scalp Serum: we checked VEGAMOUR GRO Ageless Anti-Gray Hair Serum. The nearest list: niacinamide, zinc PCA and palmitoyl tetrapeptide-20 on water, propanediol and pentylene glycol, as FutureIQ has niacinamide, zinc sulfate and the same peptide; VEGAMOUR adds caffeine and fo-ti root and has no palmitoyl dipeptide-52. Amazon US doesn't carry it, only VEGAMOUR's older GRO Hair & Scalp Serum. FutureIQ Biomimetic Longevity Hair + Scalp Serum: we checked Arey To The Root Leave-In Scalp Serum. It shares one active, palmitoyl tetrapeptide-20 amide, the anti-graying peptide, and has none of FutureIQ's niacinamide, zinc or palmitoyl dipeptide-52; the rest is glycerin with fo-ti, tangerine, ginseng and caffeine extracts. For the rest, a pair only goes up when the cheaper product matches on format, finish or key actives and is sold on Amazon US; nothing clears both bars yet.
