Note: don’t be surprised if you can’t stop running your fingers through your hair as a result (and we wouldn’t blame you).

It’s also designed to boost colour vibrancy and enhance shine, while reversing frizz-causing damage so you get immediate and long-term results. Plus, if you love using heated styling tools — it’ll protect your tresses up to 450°F (232°C).
Caprylyl Caprylate/Caprate, Squalane, Persea Gratissima (Avocado) Oil, Helianthus Annuus (Sunflower) Oil, C13-15 Alkane, Undecane, Benzyl Alcohol, Tridecane, Castor Isostearate Succinate, Propanediol, sh-Oligopeptide-78, Fragrance (Parfum), Tocopherol, Cinnamal, Hexyl Cinnamal, Limonene, Linalool.

To strengthen and reduce frizz, apply to damp, towel-dried hair from mid-lengths to ends and wait four minutes before styling. You can also apply to dry hair as a finisher to smooth flyaways and add shine. This is a highly concentrated formula, so start with 1-3 drops and build as needed.

The best
This is the best hair oil I've ever used, lightweight and not greasy. My hair feels soft and silky when I use this oil. A little goes a long way

Lightweight and leaves hair so soft
Initially I only tried the k18 hair mask but got a little travel size bottle of this oil to try out as a free gift, that lasted me forever but the second it finished I knew I had to order a bigger bottle. So lightweight not greasy at all, great for air dry days or as a finisher after I’ve applied heat to my hair

A little goes a long way
It is a very concentrated oil. I have long dry hair I only use 2 drops. If I do more than 2 or 3 drops my hair looks a bit oily.

Excellent
I have tried so many hair oils and I think I may have found the one. But like other reviews this is best applied after washing hair. Hair felt moisturised and silky without looking greasy or weighed down.

Worth it!
Wow, yes this is pricey and I found it took me a while to justify the cost but I tried the K18 hair mask and it transformed my hair so here we are. The difference between this and lower end hair oil is pretty considerable. The consistency, longevity (2 drops for long hair was plenty), instant shine and de-frizz - I just haven't had these results from anything else I've tried. This really is far superior and will last for ages. What a bonus - it smells gorgeous too!

Hair oil
This hair oil is excellent. You only need a couple of drops. It makes hair shiny and controls flyaways. Expensive but well worth the money as will last a very long time.
