    • Amazing
Size: 1 Fl Oz (Pack of 1)
This product is amazing! Just got my hair dyed and usually it gets super dry but using this product along with the k18 leave in my hair is silky, my ends are hydrated and it helps control the frizz from the summer humidity.

    • Favorite hair oil
Size: 1 Fl Oz (Pack of 1)
This will always be my favorite hair oil I couldn’t recommend it to enough people it’s so lightweight makes your hair soft and sleek and if you use the right amount it’s not oily at all which I love. If you’re not sure if you should get it, get it. I couldn’t praise enough of my love for k18 for how amazing my hair has been especially after years of bleaching it I wish I tried this brand sooner then I did ... show more

    • Molecular Repair Hair Oil
I bought this to help with my dry, damaged hair. Since using I can really tell a difference in how much healthier my hair looks and feels.

    • Works well but you need to use more than they suggest.
Size: 1 Fl Oz (Pack of 1)
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. ... show more

    • Will not buy it again
Size: 1 Fl Oz (Pack of 1)
It smells nice but is not better than cheaper argan oil in the supermarket. It is overpriced for the quantity.

    • GREAT product!!
Size: 1 Fl Oz (Pack of 1)
The media could not be loaded. 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. ... show more

    • doesnt do anything
didn’t do anything maybe if you use the full system, shampoo, conditioner, mask and oil? but the oil alone does nothing that any other oil wont do, it felt like i put nothing on my hair, lightweight is great but it didnt smooth a single strand of hair for the price, thats not ok
