Why bond-repair technology will be taking over the hair-care aisle.
Looking to strengthen damaged hair? It’s time to get scientific. “Bonds are important for moisture, elasticity and shine,” says Peter Schuetz, measurement science leader at Unilever. There are three types of bonds in our hair — ionic, covalent and hydrogen — and they act as a bridge between proteins that make up the hair fibre, so having a strong, healthy bridge is crucial for hair to look its best.
While hydrogen bonds are the most abundant, they are also the weakest and easily broken or damaged by external factors such as heat. “The new Nexxus Amino Bond line has been designed to repair hydrogen bonds, thanks to the formula’s inclusion of amino acids that are small enough to penetrate deep into the hair cortex,” says Schuetz.
Whether it’s in the form of shampoos, conditioners or masks, bond-repair technology will be taking over the hair-care aisle because these products not only rebuild broken bonds but can also prevent further internal damage.
Ahead, nine products that promise to do just that.
