A cupboard full of products can't give you the results that K18's new leave in treatment does! When it comes to damage control, this is all you need. This easy-to-use formula penetrates deep into your strands for repair on every level. The microscopic level where Keratin meets Keratin is restored by K18Peptide so less breakage occurs.

Q: Is this a genuine K18 product? The price seems so good for the amount of product considering a 1.7 oz is 75 usually.
submitted by Steph - 1 year ago
A: I have same question. only thing I could find is that this size isn't even sold on the k18 website but is on their website for hair professionals? Still a lot cheaper than there.
submitted byHome - 1 year agoA: It was sold on the k18 website as a special Jumbo size for a limited time. The price was $120. It is no longer available on the K18 website. This was in May 2025. Jumbo Leave-In Molecular Repair Hair Mask 100mL - 100 mL SKU #: K18-31008 Quantity: 2 $240.00

NOT GENUINE PRODUCT - the real k18 does not have a huge bar code on the side of the bottle. Additionally, when was the last time you saw instructions for use on a bottle use the word "usage" and NOT "directions". ITS FAKE GIRLIES, DO NOT PURCHASE.

Question whether product is authentic?

lizH - 3 years ago, Verified purchaser
I emailed k18 to make sure the product was authentic, and told the seller is not an authorized seller. Target would not let me return. I didn’t realize target sold from companies that are not authorized.
No product or pump broken

The product hardly comes out of the container. Almost like it’s empty already. I’ll pump multiple times and hardly anything comes out. I think the pump is broken.

CC - 3 years ago
The K18 mask as a whole is great. The bottle I received has tons of air bubbles and hardly any product comes out with each pump, and it seems like there isn’t the full amount of product inside. I’m afraid there was a reason that this is being sold at such a discounted/good price.

I purchased the “full” size from Sephora last year which did last me a good amount of time so when I saw this I knew it was going to be a steal!

So far so good! I have only used this twice and my dry ends look significantly better. I still need to use it awhile longer before I can say it’s amazing for certain, but overall I am happy with it so far.
