All Hair Types Tested

Over the past few weeks, we’ve tested Olaplex No.7 Bonding Oil across our diverse hair types-curly, straight, thick, and fine-and were consistently impressed. As a concentrated high-shine oil, it delivers a luxurious, lightweight finish that amplifies gloss without leaving a greasy residue. Our frizz-prone locks stayed visibly smoothed for up to 72 hours, resisting humidity and weather with ease. For color-treated hair, the formula enhanced vibrancy, keeping our strands radiant even after multiple washes. It also acts as a reliable heat protectant, shielding our hair during styling sessions while maintaining flexibility and shine. What stood out most was its adaptability: whether we used it as a finishing treatment or a pre-styling shield, it performed seamlessly. This product doesn’t just promise results-it delivers a daily touch of hydration, strength, and that coveted, salon-style shine. We’re confident it’s a must-have for anyone seeking long-lasting, healthy-looking hair with a touch of elegance.
