    • 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.

Size: 0.34 Fl Oz (Pack of 1)
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.

    • K18 revived my hair.
Size: 1 Fl Oz (Pack of 1)
I’m mature, hair starting to get a little dry, breakage and split ends were a challenge. I’ve been using K18 products and my hair looks amazing. Full, silky and I’ve add 4 inches over that past year!

    • It smells good, it’s not heavy, but that’s about it.
Size: 0.34 Fl Oz (Pack of 1)
I purchased this product after reading plenty of great reviews. First of all, it smells great. The oil has a nice consistency and does not make your hair look greasy or too heavy. However I have medium length naturally wavy hair, and this product does nothing for me. I will put some on when I notice a frizz-mania going on, but I find that it doesn’t help me. I have put the product on when my hair is wet, and I don’t notice much of a difference. I am a little disappointed because there are so many great reviews! But, unfortunately I will not be repurchasing. ... show more

    • 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

    • Overpriced and useless
Size: 0.34 Fl Oz (Pack of 1)
The suggested amount of 1-3 drops is ridiculous, especially if you have long or damaged hair. The droplet is tiny so 3 drops just disappears into the skin of your palms. Instead, I squeeze out all that’s in the droplet for each use, and even at that, I feel nothing. My hair doesn’t feel any different, and there’s still breakage. I have long hair and have been bleaching and coloring for the past 3 years, so I thought my hair type is ideal to test a product like this. Waste of money and full of pretentious false claims. ... show more
