K18 is top of its game
I’ve tried quite a few hair oils and this one is easily one of the best I’ve used. It’s really lightweight so it doesn’t leave my hair greasy, but it still makes it look smoother and shinier. I only need a couple of drops and it sorts out flyaways straight away, especially on the ends. It also works well on both damp and dry hair which I like. After a few uses my hair feels softer and a lot more manageable. It’s definitely on the pricey side, but a little goes a long way so the bottle lasts ages.

Very good for dry hair
I have course, thick, dry Mediterranean hair. Putting this on my ends has really helped my hair feel a lot softer and healthier.

It works
This product is very small. Not a lot in it but it works

I have no idea
I don't know if this is doing any thing or not, I feel like I should have got the conditioner instead or as well as (and I will do so), my hair does feel better but I'm unsure if that's due to this product or changing my whole routine. You can only use a small amount of this, and that is why it's hard to tell I think - you don't feel like you're doing anything, how can 3 drops cover a head of hair? I am trusting the science - I will update this review in a while. It is good that you don't have to use much because its expensive lol. I got it after reading reddit - great place for honest reviews , and they rave about it over there and its highly recommended for what is basically dead hair

Worth it
Great for damaged hair, brings shine to hard water damage. It’s a very thick texture so only need to use minimal, the bottle has lasted me very long so great value for money

Tengo decoloración en todo mi cabello, y este aceite no mancha mi rubio como otros aceites tipo moroccanoil.
