The luxury original: OLAPLEX No.5 Bond Maintenance Conditioner, $33.99

What matches: Olaplex's bond builder, bis-aminopropyl diglycol dimaleate, in a conditioner of the same kind: water, cetearyl and cetyl alcohols with a behentrimonium conditioner, glycerin and panthenol.

What it does worse: Olaplex softens with PPG-3 benzyl ether myristate, triglycerides and a silicone copolymer and adds quaternium-91 and a long list of oils; Maruderm uses squalane and sweet almond oil with hydrolyzed keratin, ceramide NP and amino acids, and no silicone.
