    Silky hair
    Not usually sold on products but this is def worth it just a small amount made my hair silky and not frizzy smells great. Probably could just do once a week treatment of just a couple drops!

    GREAT product!!
     I am so glad I heard about k18 products. k18 makes a huge difference in my hair. My hair is naturally frizzy and gets really dry without any real reason (maybe from hard water), but after having my hair lightened with bleach it was much worse. I ended up with a ton of split ends and breakage which was really discouraging after growing my hair out for years, but K18 hair oil and k18 leave-in hair mask has made my hair so much healthier and manageable. It helps tame the frizz and leaves my hair so silky smooth without and residue feeling. If you use to many drops it will leave you hair lightly greasy, so just test out how many drops work for your hair type and length. My hair is to the middle of my back, I have fine, frizzy wavy, dry hair and I use 1-3 drops and I apply it to the ends of my hair and work it up half way (on some of the dryer spots I will add a little more to help repair that problem area). Then I brush my hair to make sure it gets on all hair strands. I like how it is heat safe and actually can help protect you hair from heat damage.

    My hair looks shiny and healthy because of this product
    Gone is the frizzy, damaged hair I used to have before my daughter introduced me to this product. I am now starting my second bottle. It lasts a long time and smells great. A very small amount, about the size of a pea, is enough. Had I not suffered a “travel mishap” I would still be using my original bottle!

    Works well but you need to use more than they suggest.
    It smells nice and seems to really smooth my hair well, but they recommend using 3 drops. I have hair that is about 1″ below my shoulders and I need to use more like 8-10 drops. And it’s a fine line between getting the right amount and too much. If you overdo it your hair will look a bit greasy. But when you get it just right, it does give your hair a sleek gloss.

    Will not buy it again
    It smells nice but is not better than cheaper argan oil in the supermarket. It is overpriced for the quantity.

    Hair treatment
    I have used product once; hair is so much softer; really help with detangleing

    Useless
    This was super expensive and it did nothing. I have thin fine dry hair. 3-5 drops does nothing. More than that weights my hair down making it look flat (and still dry). Don’t recommend.

    Kein Wundermittel, machte bei mir aber meine nicht mehr kämmbaren extrem trockenen kaputten Spitzen wieder viel ansehnlicher und vor allem kämmbarer. Teuer aber das kaufe ich bestimmt nach, wenn es leer wird, da es sehr sparsam im gebrauch ist lohnt es sich trotzdem.

    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
