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.

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.

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. Please note that Royal Mail currently classes perfumes, nail polishes, flammable liquids and aerosols as "hazardous materials" and will only accept a limited number of these per parcel. A patented oligopeptide called K18peptide. This replaces lost amino acids to repair the hairs keratin structure. Benefits: 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: 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.

Key BenefitsI'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? 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
