Why You Should Avoid Olaplex and K18 on Hair Extensions

It's a common misconception-even among professional stylists-that treatments like Olaplex and K18 are universally beneficial for all types of hair. While these products are excellent for repairing and strengthening natural hair, they can actually cause more harm than good when used on hair extensions. At Perfect Locks, we've received numerous reports from customers and stylists alike, describing how extensions became dry, brittle, and even broke off after these treatments were applied.

So why exactly are these popular treatments unsuitable for hair extensions? The answer lies in both the formulation of these products and the unique nature of hair extensions themselves.

The Protein Problem

Bond-repair treatments such as Olaplex and K18 are loaded with proteins and active ingredients designed to rebuild broken bonds within natural hair. Natural hair is alive at the root, has a steady supply of nutrients, and can typically handle these treatments—sometimes even thriving because of them.

Hair extensions, on the other hand, are not the same. Although they may be made from 100% human hair, they are no longer connected to a living scalp and therefore lack the ability to repair or regenerate. They’ve also undergone a meticulous hair manufacturing process, aligning the cuticles in a specific direction for optimal shine, softness, and longevity. Introducing high levels of protein into this delicate balance can disrupt the cuticle alignment, leading to dryness, frizz, tangling, and even irreversible damage to the hair shaft.

Less Resilient, More Vulnerable

Unlike your natural hair, extensions are significantly less resilient to chemical and environmental changes. Once damaged, they can't recover in the same way that natural hair can. Overloading them with protein-rich treatments often leads to brittleness and breakage, shortening the lifespan of your investment.
