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? 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. Reverse hair damage with the K18 Leave-in Molecular Repair Hair Mask, a leave-in treatment mask designed to restore the hair in just four minutes. Bleach, colour treatment, chemical services and heat can all wreak havoc on the hair. Powered by the K18PEPTIDE™, this haircare treatment can help repair the damage. Giving both immediate and lasting results, it helps restore strength, smoothness, softness and bounce. Your hair can suffer from damage from bleach, hair colour, chemical services, heat styling and sun damage. This damage can go below the top layer of your hair and into the lower levels, the deepest of these are made up of polypeptide chains.

By reconnecting these polypeptide chains, the mask strengthens along the length and width of the hair, offering a full 360 approach. Probably the best thing you can do with K18 is not think of it as a hair mask at all. It's pretty far away from giant tubs of goop that you apply in the bath to make your hair feel all slippy and smell nice.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). In comparison, Olaplex uses patented Olaplex Bond Building Technology ™, that rebuilds broken disulfide bonds to restore strength. 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. Working at the innermost layer of the hair, this vegan-friendly mask can even get to work on extreme damage. Boosting core strength and elasticity, it helps reduce split ends, breakage and colour fade. With lightweight moisturising benefits, it will not weigh down the strands as it helps prevent tangling for hair that looks and feels renewed. Key Benefits 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. I let my hair air dry, as I do most weekdays, and that was that! Considering how much high-tech action is taking place within the hair, I found K18 refreshingly low-fi in terms of protocol. This in itself is a huge selling point as it allows for consistency –even the best hair products are no good if you can't be bothered to use them. K18 results

I've now used the K18 mask four times over as many weeks and have noticed a nice, gradual improvement in texture and strength. My long highlighted hair (that I'm sure any stylist would say is overdue a cut) looks less straggly and piecey through the ends. Plus, I trust this product, so I feel better about my hair as I know I'm taking care of its health. It makes a lovely change from my usual 'bleach and blow-dry now, pray later' policy. that violates any law, statute, ordinance or regulation (including, but not limited to, those governing export control, consumer protection, unfair competition, anti-discrimination or false advertising); With most hair treatments being either conditioners that encase strands in superficial hydration and shine, or repairing treatments that work to patch up damage for temporary results, K18 has broken the hair care mold. Enter: the K18Peptide – a patented molecule that travels to the very innermost layer of your tresses, where it repairs broken bonds and restores hair’s strength and elasticity. Usually, repairing formulas work on the outer structures — the hair bonds. But K18 is the only brand that dreams up products to work on the vertical polypeptide bonds, molecularly changing and repairing the polypeptide chains that have been broken, as well as reconnecting the disulfide bonds. This is biotech hair wizardry for stronger, healthier strands from within. K18 will help your hair colour last longer and over a period of use and strengthening of your hair, this will allow your hair colourist and hair stylist to really create some fantastic and lasting results! Key ingredients: This is pretty unique and difficult to achieve. After it leaves your scalp, your hair is by all intents and purposes dead. So unlike your best skincare products, applying topical lotions and potions to your hair can't generally give it much help to regenerate and restore itself. These are not living cells, so that ship has sailed.
