Why you need it

K18 Leave-in Molecular Repair Hair Mask is an at-home hair treatment infused with patented K18Peptide™ that works to repair even the most extreme damage, renewing hair to it's most youthful, healthy state.

This patented K18Peptide™ creates hair like new by travelling deeper into the inner layers of the hair compared to traditional repair products, to reconnect broken keratin chains, renewing hair strength, softness, smoothness, and bounce. You can feel and see the difference with the first use. This formula doesn't wash away with shampoo, leaving lasting results, healing damage from bleach, colour, chemical services and heat.

Free from: Vegan, Cruelty Free, Sulphate Free, Paraben Free, Phthalate Free, Silicone Free, Artificial Colour Free, Sodium Chloride Free, Formaldehyde Free.

how to use
Shampoo, do not condition so the mask will penetrate hair more effectively. Towel dry hair until damp. Start with one pump and add more as needed. A little goes a long way. Work evenly into hair, one pump at a time, starting from ends to roots. Let sit for four minutes to activate. Do not rinse out. Style as usual.

Tip: Use a clarifying shampoo if you're a heavy product or dry shampoo user to remove buildup and help the peptide penetrate and get where it needs to go. Wait the full 4 minutes before styling or applying other product.

Damaged my hair

Completely damaged my hair and caused severe breakage. One look at the ingredients : alcohol is the main one! If you already have dry or damaged hair it can only destroy it more.

Hair feels great

Okay

I was recommended this by my hairdresser after having it bleached and toned. I have quite dry hair naturally, and was hoping this would revive it as it was damaged by the bleach. It helps a bit, but not as much as I was hoping. I find I have to use an awful lot of it and my hair still feels very dry after use, so I add in some hair oil. Perhaps it's better suited for less dry hair? I would recommend trying it, and I'm going to continue use to see how it goes - just not sure it's worth the cost.

Disappointed

I was expecting a lot from this product, but I was disappointed as it did very little for my dry frizzy hair.

Expected more

I got this after reading great reviews but for the price I don't feel it's great. You need more than 2 pumps if you have medium lenght hair, after a week of using it it's almost gone. My hair doesn't feel any different.
