Those who struggle with dry hair that easily snaps and looks dry and brittle are turning to the K18 Leave-In Repair Hair Mask.
The hair mask is designed to not only restore and hydrate the hair follicles, but also reduce split ends and breakage.
The mask gets to work thanks to the unique K18Peptide, which the brand claims is just the right size and makeup to reconnect broken chains responsible for hair strength and elasticity.
Traveling into the inner-most layers of hair, the mask restores hair from the inside out. As a result, it has drawn comparisons to Olaplex but with many users agreeing it performs better noting ‘incredible results’.

Thousands of Amazon shoppers have shared their honest reviews with the K18 Leave-In Repair Mask and have posted their transformations, and close to 5,000 have been wowed.
One five-star review raved: ‘This works. I used to be an Olaplex junkie but this fixed my damaged and fried hair faster.
Another agreed, adding: ‘About a year ago my hair started breaking, shedding and thinning quite significantly. I was recommended this mask by my hairdresser to help strengthen my strands. My hair has absolutely loved this treatment. My hair is stronger, more elastic and curlier than ever.’
A third penned: ‘Worth every penny spent, my hair is soft, shiny and extremely manageable, I now only need to straighten once a week, 100 per cent better than Olaplex.’
