The brand's popular weekly pre-shampoo treatment repairs and prevents damage, whereas the K18 mask works to restore your hair to its previous state. I've tried a lot of hair-bonding treatments out there (read my review of my go-to serum here) and I never found Olaplex did quite enough for me, so would K18 be different? The first mistake I think you can make with this range is using it like your normal haircare range. In fact, I had to have my phone at the side of the shower just to make sure I got this exactly right (risky but necessary). K18PEPTIDE™ is in all our products and is an incredible peptide that can reverse damage at a molecular level in the polypeptide chain, renewing strength and elasticity on all hair types," explains Jordan Alexander, Senior Director of Global Education at K18.

Spoiler: I did find it worked better than you-know-who, and the results weren't just flushed down the drain in the next wash (whether I was using K18 products or not). How to use K18 Yep, that's right, you can use K18 products on all hair types, textures and colours (even if you're a bottle redhead like Moi). Is K18 better than Olaplex? It's worth noting that the brand recommends working it into the hair from the ends to the roots, however I did actually avoid the roots at first as I was worried about them looking (and feeling) greasy.By reconnecting these polypeptide chains, the mask strengthens along the length and width of the hair, offering a full 360 approach. Even some of the best 'damage repair' hair ranges out there has only been a temporary fix for my strands, so I was intrigued by K18's long-lasting repair claims.
