Have you ever thought about shaving your dry, damaged hair off and starting over? Because if so, same. Bleaching, chemical processing, heat styling, and even too-tight ponytails can lead to perpetual frizz and split ends so brittle, you're not sure any amount of deep conditioning will revive them. My best-friend-turned-hair-dresser would agree that sometimes the only way to get rid of lifeless hair is to chop it, but before you schedule a salon appointment, try Olaplex No. 7 Bonding Oil. Over 16,000 Amazon shoppers swear it makes their hair feel soft, shiny, and silky within just a week.
Olaplex knows its stuff. The haircare brand launched in 2014 and has had a following ever since, from celebrities like Kim Kardashian to master colorists and stylists to the stars. Its most famous product is arguably the No. 3 Repairing Treatment — the leave-in treatment with almost 100,000 Amazon reviews — but Amazon shoppers seem to be equally loyal to the No. 7 Bonding Oil.

The oil uses the brand's signature ingredient, bis-aminopropyl diglycol dimaleate, which is just a fancy name for a molecule that helps to bond the hair's structure back together when it's broken and damaged. The oil is incredibly hydrating, but still weightless and grease-free. It works to moisturize dry, damaged hair while adding shine, vibrancy, and softness.
It's not just a conditioning formula, either — the oil protects hair from heat styling products up to 450-degrees Fahrenheit. Just apply a few drops to wet or dry hair before using a flat iron, curling iron, or blow dryer — customers note that a little goes a long way, so you just need a few drops to reap the benefits. In fact, the bottle is actually designed to dispense the right amount so you never overuse the product.
One shopper writes that the oil "immediately took years off" their mature hair, saying it also replaced their other styling cream, hair oils, and heat protectants: "The very first use, my hair was immediately smooth, soft and silky," they write. "I had no issues with humidity, saw beautiful shine, my hair curled easily and overall looked so healthy and beautiful."
"I could see a difference even after one use," writes another customer. "I used only a few tiny drops and the effect is unbelievable. I wouldn't believe it if I read it but believe me —I had the worst hair quality because of a poor bleach job and two dye jobs. I thought there was no hope for my hair, but because of this product, you wouldn't even know I have damaged hair."
A third simply calls it "liquid gold."
