Olaplex, facing a new lawsuit over its hair products, said tests show its products are safe.
The brand, a staple in TikTok hair care routines, posted "third-party" test records on its website.
"As such, there is no induced inflammation to the hair follicle, which is the primary cause of hair loss."
The test reports that Olaplex posted were issued by a number of laboratories including BioScreen Testing Services Inc., Consumer Product Testing Company, and Brazil-based Allergisa Pesquisa Dermato Cosmética Ltda.
A representative for Olaplex said on Wednesday that the HRIPT reports are "industry standard and reflect the use of Olaplex products under real world conditions."
