When something is really good, people will be searching for dupes. There are similar treatments to Olaplex for professional and at-home use. One example is Joico's K-PAK Reconstructor, a deep conditioning treatment that restores broken bonds caused by chemical services and heat styling, says Joico brand ambassador Larisa Love. Similarly, Redken offers a pH-Bonder salon treatment with a pH-Bonder Post-Service Perfector, $16, for at-home maintenance. L'Oreal Professionnel's Smartbond system is described as the "perfect complement to its colors and lighteners" and protects and fortifies hair during service. Other brands with systems include b3 Brazilian Bond Build3r and Schwarzkopf with its Fibreplex.

No matter which treatment you get, ensure that it's done by a licensed professional and do your research. Consider what other hair treatments you're getting done, maintenance, at-home care and the stylist's experience. And don't be afraid to ask questions.
