Olaplex Showdown: Bonding Oil Versus Concentrated Shine, Tested… Защита отHeat! In Olaplex Showdown: Bonding Oil Versus Concentrated Shine, Tested… Защита отHeat!, we delved into the differences between Olaplex No. 7 Bonding Oil and Concentrated High Shine Oil, Vi. While both offer protection, our tests revealed distinct purposes. The Bonding Oil, with its dual role as a heat shield and bond builder, proved indispensable for our high-heat styling sessions. We noticed ourselves relying on it to rescue damaged hair, thanks to its reparative properties. On the other hand, the Concentrated Shine Oil, lighter and more versatile, excelled in delivering a polished finish without weighing down our locks. We learned that the Bonding Oil is best layered before heat styling, ensuring our hair remains intact. Meanwhile, the Shine Oil is a post-styling refiner, perfect for a sleek, touchable end. Both are essentials, but their functions couldn’t be more tailored.
