"The customers say in the lawsuit that Olaplex use ingredients that can cause allergic reactions and are banned in Europe"
In response to the lawsuit, an company spokesperson for Olaplex said “We have publicly released test results from independent third-party laboratories, going above and beyond industry standards, to demonstrate this. We have full confidence and believe in the safety and efficacy of our products,”
"The plaintiffs are seeking more than $75,000 in damages."
