4-minute leave-in treatment to reverse damage

Hair like new. This leave-in mask heals and strengthens hair with lightweight moisturizing benefits to detangle and keep hair smooth and soft, without weighing it down.

    I was really unsure if I get the bigger bottle due to price point. I’ve only had the product for a couple of weeks and have noticed a significant improvement in the integrity of my hair. I have very fine thin hair naturally which I have been dying a level 3 for years. My hairdresser did some balayage and was able to lighten it without a lot of damage and I really believe it’s because of this product!

    I've only used this product three times but it's already made my hair so so soft and sleek. My hair was quite kinky and frizzy, with a lot of split ends, and it didn't really sit nicely when straightened. Now it's flat and feels moisturised even three days after washing. I highly recommend buying this hair mask at least once!

    K18 has completely changed my hair from thick and frizzy to thick and smooth. 3 applications in and my hair is so soft. A little goes a long way and it's not noticeable in your hair.

    I have fine broken hair around my hairline. This product came highly recommended. I have used exactly as per the instructions and my hair is certainly smooth, less tangled, and the ends are already improving which if nothing else will encourage it to grow! Leaves less of a dry brittle feel than a purely protein-based treatment. Happy to pay the price for a product that delivers. So far so good. ...

    K18 Biomimetic Molecular Repair Mask actually works. Previously I was spending $$$$ on the Olap**x range 1-7... and while they helped considerably, it's no comparison to K18. Now this one product has replaced all of them and my conditioner. My hair has never felt better, and I have nowhere near the breakages after each colouring (blonde) session. The best change! And the cost is worth it, I'm actually saving money and I've reduced how many plastic bottles are cluttering my bathroom and recycling bin.

    I am blown away how much of an improvement to my dry, bleached hair this has made . I can NEVER blow dry my hair without creating a big fuzzy mess, but just once after using this , it’s smooth and sleek. Worth every penny ! Tip , don’t use too much and emulsify between your hands (rub together ) before applying !

    I have VERY curly hair and have been heat treating for years so expected to see some good results - unfortunately this hasn’t improved the condition of my hair much after 5 uses. The curls seem if anything less intact than they were. Since stopping uses and deep conditioning it’s starting to get a bit better but not what I was hoping for! Disappointing considering the cost

    I’ve been a religious Olaplex user for 2-3 ish years now and this mask is officially my new go-to. I read so many reviews on this before buying and I was skeptical but holy cow my hair feels like it did before I fried it off from bleaching. If you’re hesitant about buying this, don’t be. It’s freaking amazing and well worth every cent. I’m going to buy 5 more bottles to make sure I never run out.
