hard pass
I use K18 mask instead of conditioner and love it. but, this hair oil does nothing. for the price, there's better out there. can't say anything overly positive about it. it's a big skip

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!

Meh
I bought purely because the leave in treatment was a saviour. I just don’t get the hype. I didn’t notice anything spectacular and much prefer other oils on the market. Left my hair feeling v dry

Please change the bottle design!
I'm sure it works but I hate it and the bottle design. 3 stars because the product didn't suck as much as the bottle. Wasted half of it just by tipping it over. NOT FOR THE CLUMSY!
