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.

What It Does

This silicone-free oil fights frizz differently by addressing the damage that causes frizz long-term and immediately smoothing frizz + flyaways.

Rated 4 out of 5 by from Pleasantly Surprised!! I have really long, thick, color treated hair that tends to be pretty dry, especially on the ends. This K-18 hair oil has made my hair soft as well as reducing tangles! I only used about 2 droppers on damp hair and air dried, and I thought there was no way it'd be enough, but to my surprise, it was PERFECT! I'm definitely happy with this product and would keep it in my rotation.

Rated 4 out of 5 by from Not greasy I’ve always wanted to try the K18 products so I figured starting with the oil would be good. I’ve been using it on myself before clients and I have fine long straight hair so oils can make my hair greasy easily. I feel like this is a more dry oil which is nice and it doesn’t leave a residue on my hair when I let it air dry.

Rated 4 out of 5 by from Good oil Really enjoy this oil! Very thin feels like it penetrates very deeply. Excited to see the benefits as I use it longer. Definitely enjoy it more in wet hair than in dry.

Rated 5 out of 5 by from Good for dried and fizzy hair I got this product for free from Influenster and K18 and I tested it. This product is perfect for people with dry and fizzy hair like mine. After washing my hair, I dried it with towel and apply the product to style it. The hair then became so soft and smooth, making styling it so easy and it came out perfect. The hair stays perfectly for days. I also love that the scent is not so strong. You don’t have itching or irritation after using the product.

Rated 4 out of 5 by from Great hair repair I recently had the chance to try the K18 Molecular Repair Hair Oil for free from Influenster. This product claims to repair and strengthen damaged hair at a molecular level, and I have to say, it delivered on its promises. The lightweight formula absorbs quickly, leaving my hair noticeably softer and more manageable. I appreciate that it doesn't weigh down my hair or make it greasy. With consistent use, I noticed a significant improvement in the overall health of my hair, with less breakage and more shine. The subtle, pleasant scent adds to the positive experience. Although the price is higher than some other hair oils on the market, the results make it worth the investment for those in need of an effective solution for damaged hair. Overall, the K18 Molecular Repair Hair Oil has become a staple in my hair care routine, and I highly recommend it to others looking to revive and nourish their locks.

Rated 5 out of 5 by from AMAZING This hair oil shocked me! I have naturally wavy hair and am no stranger to frizz. I was always just used to it. After trying this oil I couldn’t believe what a difference it made. I have thin hair but high hair density and use about six drops for all my hair (very concentrated) my hair not only gets smooth but stays smooth all day! This oil can be heavy so be very careful not to put too much. Has a subtle smell that doesn’t last long. I’m such a big fan of this stuff!! *I was sent this product in exchange for a review*

Rated 5 out of 5 by from perfect for smoothing the hair I use this before blow drying especially on frizzy/texture hair and it makes the hair so shiny and soft. Zero frizz. So impressed with this oil.

Rated 5 out of 5 by from Need Only 3 Drops Max I love K18 and this oil has been a game changer. YOU ONLY NEED 3 DROPS MAX NOT A FULL DROPPER. It's a thin formula that goes a long way. My hair feels healthier than it's ever been since using the K18 mask and oil and all my clients are having great results.

Rated 1 out of 5 by from Smells amazing but way too heavy I initially used 3 pumps on my long fine highlighted blonde hair. WAY too heavy, so I used 1 pump the next time. Still too heavy and oily. Leaves the weirdest coating on the hair, like it sits on top of the hair and doesn’t absorb. Makes my hair feel dry and gross at the same time and I can barely get a brush through it. This is using it wet and dry both. I even tried it on dry hair only and it just sits on top of the hair and causes major build up. My hair has never felt so disgusting. So bummed and had such high hopes, because I love the K18 mask! I’m going to try the L’anza silk serum instead.
