The luxury original: OLAPLEX No.6 Bond Smoother, $29.97

What matches: A leave-in cream on the same frame, with Olaplex's bond builder: water, cetearyl alcohol, a behentrimonium conditioner and propanediol, with bis-aminopropyl diglycol dimaleate and the same hydrolyzed vegetable protein PG-propyl silanetriol.

What it does worse: 6 smooths with dimethicone, phenyl trimethicone, isohexadecane and esters, so it holds frizz down harder; Maruderm has no silicone oil and leans on glycerin, squalane, sodium hyaluronate and keratin, with polysilicone-15, a UV filter.
