• Provides heat protection up to 450°F

Note: At LovelySkin, we take your health and the health of your hair seriously. We have contacted OLAPLEX and spoken with their scientists about the recently announced issues. From statements by their scientists and CEO, it appears that there is no reason to believe that OLAPLEX products cause hair loss or hair breakage. Every OLAPLEX product is thoroughly tested by both their in-house formulators, as well as independent third-party laboratories. They use industry-standard Human Repeat Insult Patch Tests, also known as HRIPT, in which every OLAPLEX product is tested on humans to ensure it doesn’t cause skin irritation, inflammation or sensitivity. When hair products pass these industry-standard tests, it also means there is no caused inflammation to the hair follicle, which is a known cause of hair loss. If you are interested, you can read these findings on the OLAPLEX website.
