This shine-boosting, strand-strengthening elixir doesn't just make hair look healthier. It actually brings it back to life.
Written By ANNIE TOMLIN
Widely regarded as the holy grail of hair repair, this groundbreaking treatment has become legendary among salon regulars, thanks to its ability to rebuild the microscopic bonds that keep strands smooth, strong, and intact. Its proprietary and patented star molecule, bis-aminopropyl diglycol dimaleate (BDD), seeks out individual sulfur hydrogen bonds along the hair shaft and brings them back together. The end result doesn't simply patch over the problem; it literally returns hair to its pre-damaged state to make it healthy again.
Between salon visits, addressing damage can be as simple as doing your hair. Olaplex No. 7 Bonding Oil, the latest addition to a suite of reparative at-home products, is a highly concentrated, lightweight oil that's part healing elixir, part styling aid. A few drops (applied to dry or damp hair) is enough to protect against heat-styling damage, shield from the sun's UV rays, soften and smooth, minimize flyaways, and detangle after washing. As you incorporate it into your hair care regimen, you'll see fewer split ends, less breakage, and significantly more strength.
For the ingredient-aware, the vegan formula is cruelty-, paraben- and gluten-free—and loaded with hero molecule BDD. Here, it's assisted by grape seed oil (rich in shine-boosting essential fatty acids) and fermented green tea oil to encourage hair growth. But even if chemistry isn't your strong suit, all you need to know is this: If your hair is even slightly lackluster, damaged, or fragile, this oil not just a "nice to have." It's essential.
"Sign me up for everything Olaplex. I already use their shampoo and conditioner, and this magic oil immediately reduced my frizz using just a few drops. I also like that it dispenses just the right amount each time so there’s no waste. One drop did the trick!" —Emily Morse, Doctor of Human Sexuality & Host of the Sex with Emily Podcast
"Healthy hair is always in, and this is one of the fastest ways I’ve been able to repair and strengthen damaged hair. From the first use, I noticed shinier, stronger, more vibrant hair. Small but mighty."
—Sunnie Brook, Hairstylist
"This is the first oil I’ve found that treats hair without weighing it down or affecting my styling."
—Christine Bullock, Fitness and Lifestyle Expert
