  • Description

    This biotech-engineered weightless oil works on all hair types to strengthen, repair damage, reduce frizz at two levels of the hair fiber, and improve shine.

    Reverses damage caused by frizz
    Smooths frizz and flyaways
    Enhances shine and color vibrancy

    This strengthening, smoothing hair oil works on two levels of the hair fiber to fight frizz. The K18PEPTIDE™ works to address deeper level damage that causes frizz, repairing and strengthening damage at the innermost layer of the hair fiber to reverse damage that leads to frizz.

    On the surface of hair, natural oils like avocado and sunflower oil and hemisqualane and squalane nurture while smoothing frizz and flyaways to improve color vibrancy, enhance shine, and provide heat protection up to 450°F (232°C).

    Clinical Results:
    In a 3rd party clinical study, one use of the K18 Molecular Repair Hair Oil delivered:

    - 24-hour frizz control*
    - 104% improvement in shine**
    - 78% reduction in split ends***

    *Results observed on curly, frizzy hair after 24 hours in 80% relative humidity, with one application of molecular repair hair oil on dry or damp hair
    **Results observed after a single application of molecular repair hair oil on dry hair
    ***Results observed on bleached/damaged hair after one application of molecular repair hair oil on dry hair

    - K18PEPTIDE™ reverses hair damage that causes frizz, promotes strength and smoothness. Hemisqualane and Squalane reinforce hair's moisture barrier, smooth flyaways, enhance shine.
    - Avocado Oil provides heat protection up to 450°F (232°C).
    - This product is vegan and cruelty-free.
    - Fragrance Description: Fresh floral scent

Only hair oil that doesn't weigh down my curls!

Wowwww! Little goes a very long way with this product. I have seen a noticeable difference within one use. I would buy this product all over again. k18 is the way to go!

Noticeable results.

I used the oil after my K18 mask, and you truly see a difference. My hair looks healthy and shiny. Start lightly with it as it's a heavier oil. A little goes a long way!

Unfortunately, for my hair, this oil did nothing other than make it dry and kind of rough too. Didn’t add any shine or softness. Could just be that my hair in particular didn’t react well to it though. My hair reacts better to the Olaplex oil. Plex oil.

My hair is the healthiest it’s ever been. I am black with relaxed hair. This oil has increased moisture and shine in my hair. I can’t live without it.

HOLY GRAIL

My hairdresser put me on to k18 bc she told me it’s the best thing you can put on your hair. I’ve been using the shampoo/conditioner and mask for months but just tried this little baby and WOW!!!! My hair looks and feels like I just got out of the salon chair. Cannot recommend enough!

Not Impressed

Somehow this made my hair extra frizzy with the texture of straw.

Really wanted to like this hair oil, but was unimpressed. It does make your hair look shiny, but nothing else. Definitely not worth the price.

Love love this product!

My hair professional has used K18 products for the past year. We have been experimenting with my gray/brown hair transformation and my hair has been colored, glazed, highlighted, and lowlighted. My ends were very dry, I have a long bob. I used 3-4 drops of this oil on my ends and immediately could see a difference. The overly dry ends turned silky and held its curl. I highly recommend this product. The K18 conditioning products my hair stylist has used after a color process leave my hair soft and manageable.

This hair oil did nothing at all, it didn't even feel smooth, nourishing, no shine, or do anything, definitely not buying again.

TIP for using the dropper!

I think it did a good job in moisturizing my ends but it didn't really wow me, especially for the price. That said, I didn't notice anything bad either. TIP for using the dropper: Screw the top closed, then pump about 6 or more times. Once you take the top off, the dropper will be full. In the beginning, I would barely get like 3 drops but then figured it out. Hope this helps!
