Olaplex first launched in 2014 with two salon-only products and a mission to protect hair during colouring. At a time when bleach often led to breakage, its patented bond-building technology aimed to repair hair from within by rebuilding disulphide bonds compromised during bleaching and dyeing. This structural approach marked an early step in the 'skinification' of haircare, shifting focus from surface shine to internal health.
The brand's at-home range has since expanded, but not all products are equal. A standout is the no.3 hair perfector, the brand's first home treatment, which remains a cult favourite. A newer version, the no.3 bond repair treatment, works in as little as three minutes and includes shea butter, avocado and sunflower seed oils, and sodium PCA for hydration and frizz control. On fine, colour-treated hair, it delivers immediate smoothness and shine, and regular use reduces breakage.
For fine hair, the no.4 bond maintenance shampoo offers a lighter formula with the same bond-building benefits. It lathers gently, leaves hair clean without stripping, and maintains movement and brightness. The no.5 bond maintenance conditioner, formulated with hyaluronic acid, provides lightweight hydration that makes detangling easier and leaves hair softer and more voluminous without weighing it down.
The no.6 bond smoother leave-in treatment is a top performer for dry or frizz-prone hair. A small amount smooths lengths, tames flyaways, and reduces blow-dry time, giving a salon-quality finish. For those seeking a complete routine, these products integrate seamlessly and deliver noticeable improvements in strength and shine.
