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.

Not Incentives Review
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!

Not the best
Absorbs quickly but otherwise quite a mediocre hair oil. I didn’t notice it did much for my fine, curly, frizzy hair. The price is pretty ridiculous as well for such an ineffective product.

K18
I LOVE the K18 brand, I am a reoccurring purchaser for the leave in condition, but this hair oil was disappointing :/ When applying this to my hair, it glides very dry. Almost like a cat licking. Not sure if y’all can imagine but it didn’t work for me. Doesn’t leave the hair soft as imagined.

Brings back shine
Originally got this as one of the 100pt rewards and then came back to order the full size. Love adding a few drops after blow-drying my hair to bring back the shine and settle flyaways.

A must have
I received only a sample size of this, I applied 3-4 drops in my damp towel dried hair then let air dry. My hair is dry, brittle and damaged but it dried so soft and silky with just a few drops. I will definitely be using this in my hair routine from now on

I don’t get the hype…
Sorry! Not sure what the hype is… I tried this and I felt the product was thin. It did nothing for my hair after trying it for 3 months :( I wish I loved it like everyone else! It’s a no for me!

Molecular Repair Hair Oil
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.
