Description
A reparative leave-in mask.
Want hair that looks brand new? Try the K18 Leave-In Repair Mask. Made with K18PEPTIDE™ (a patented bioactive peptide treatment), this leave-in mask is clinically proven to reverse damage in four minutes. Delivering repair from the inside out, this mask works to heal damage caused by bleach, colour, chemical services, heat, and mechanical styling. Offering lightweight moisturising benefits, this no-rinse-needed mask renews the hair’s strength, softness, smoothness, and bounce without weighing it down. With a long-lasting formula that doesn’t wash away with shampoo, this mask minimises breakage, split ends, and colour fading (thanks to its pH balance of 5.0-6.0).

K18 Hair Leave-In Molecular Repair Hair Mask
I havw ordered from beauty bay multiple times and habe ordered this product before. I was dispapoitned for them to send me a counterfit product. They have however refunded me but not given me any compensation as apparently it gets sent directly from the supplier so they have no 'involvement'. Disappointed and i dont know if i can trust beauty bay with haircare products anymore

K18 Hair Leave-In Molecular Repair Hair Mask
Bought this as was recommended by hairdresser. Easy to use and don't need very much so bottle does last. Hair feels so soft and doesn't leave it greasy. Only used it 3 times so far and condition of my hair is amazing. Definitely recommend

I mean, this is magic for damaged, bleached hair like mine. Takes a moment to get your head around how to use it but it's totally worth it. It's my ride or die hair product.

K18 Hair Leave-In Molecular Repair Hair Mask
I love the convenience aspect of this treatment - no waiting around for conditioner or Olaplex to work. However I feel like this is the same thing that brings this product down. Using it four times in a row then every other wash = no conditioner, which for those with curly hair is a big problem! Of course, I used leave-in conditioner after the 4 minutes, but it wasn’t enough. My hair was left really dry - I suspect it’s due to the high levels of denatured alcohol. My hairdresser didn’t notice any improvement in my hair either. I have personally seen a bigger difference from using Olaplex long-term and would suggest those with curly or wavy hair to spend your money on 0 and 3 instead.

K18 Hair Leave-In Molecular Repair Hair Mask
I really wanted to love this product as it certainly isn’t cheap! I wasn’t disappointed. I let my hair dry naturally first couple of times after using and was very pleased with the texture of my hair. I have fine hair but lots of it -it has been colour treated for many years now but K18 seems to have knocked off a few years!
