WATCH: Tested and Trusted: A Message from OLAPLEX Chief Science Officer Lavinia Popescu

Hear from OLAPLEX Chief Science Officer Lavinia Popescu on the strength of OLAPLEX testing results and ingredients. ✔️ All OLAPLEX products have been tested using a Human Repeat Insult Patch Test (HRIPT) which is the industry standard. ✔️ No irritation, inflammation, or sensitivity occurred in subjects of these tests – meaning our products successfully passed this test. ✔️ As such, there is no induced inflammation to the hair follicle, which is the primary cause of hair loss. ✔️ In addition to the standard HRIPT test, we conducted testing on sensitive skin for several product lines to further ensure the safety of our products. Our products passed these tests too.
