$3000 spent on hair products & this is my fav go to
Hello, so I really do like this one allot. I have spent about $3000 on higher quality hair products over the last cpl months bincluding this line but out of ALL the leave in conditioners I've bought I like this one the best. The bottle is a great size at 8.5 oz, is very creamy & lasts a long time. What's also a plus to me is it still works great on top/over every other product I've put in my hair. In my video you'll see it is a thicker consistency compared to most (& all of what I've bought) & this works out best for my hair which is colored, damaged, dry & frizzy. Also what I love is that I can always use it on top of everything else I have in my hair even if I'm on the road & have not washed my hair for a few days but keep using product I can still wet my hair with my fingers/hands & reapply this & it is like new! I'm not sure if it helps with shine but it does make my hair softer & most of all helps with the dryness & with taming most of my frizz. This one can also be used on wet or dry hair. If your hair sounds like mine definitely give this one a try.

Game-Changer for Damaged Hair!
I’ve tried so many products for my dry, color-treated hair, and K18 is one of the few that actually delivers noticeable results. After just a few uses, my hair felt softer, smoother, and much stronger. The shampoo cleanses without stripping, and the conditioner leaves my hair feeling hydrated but not weighed down. My hair also has more shine and less breakage, which is a huge win. Definitely pricey, but a little goes a long way — and the results make it worth every penny. Highly recommend for anyone dealing with damage or just wanting healthier hair!

SO GOOD
I love K18 so much. I started out with their Air Wash and have now switched most of my hair products to K18. They work so well. My hair is so soft and silky now. I live in a very dry climate and it has been a lot of effort to figure out how to care for my hair coming from a humid climate. K18 has been a game changer. My hair feels so clean and soft and alive again. A little of this conditioner goes a long way also so even though it’s a bit pricey it lasts for a long time.

Expensive But Worth It!
I’ve been using this product for years before I blow dry my hair. You have to just make sure that your hair is damp and towel dried not wet or it won’t work. When you apply it, leave it on for four minutes. Don’t rub it in and then come out in four minutes and use whatever other product you want it won’t make your hair greasy but instead very glossy unhealthy looking. The price point I believe, is very high for this, but it does last for quite a few months if you use it just once a week.

Good restorative hair product!
It restored my mature hair with one use! Though I would suggest using it every second or third washing for fine, thin hair..haha like most restorative products. K18 has break through hair products!

Super cute, very well made 💅🖤🤍
Really cute, thick enough not to crack on you, 3d flowers are actually 3D! Comes with mini file, glue and cuticle stick, and it was on sale! Would purchase again 💜 Only thing is, I wish we could pick out sizing. I was sent a medium and I can make it work but I’m usually XS/S.

Not as conditioning as I’d hope!
I’ve used this for 2 weeks and still don’t feel it conditions my hair enough. I Thu k its lacking moisturizer technology. My hair does not feel as soft the days following, which is a shame for the price. I will continue to use in hopes my hair adapts to it.

Never again !
I’m pretty angry about this . I don’t have the best eyesight and had I seen that I was paying SO MUCH for one once off shampoo and one once off conditioner I certainly would never have made this order ! How ridiculous !! One one bottles ! I’m attaching a photo . It’s a good thing I don’t have long thick hair any more because this would only have been one use 😡

Deep Hydration for Thick, Heavy Hair
I have very thick, heavy hair, colored hair and finding a deep conditioner that truly nourishes without leaving it feeling weighed down can be challenging. This conditioner leaves my hair feeling softer, smoother, and much easier to manage. It provides great hydration, helps reduce dryness, and leaves my hair looking healthier after each use. I love how it improves the texture without making my hair feel greasy. Definitely a great addition to my hair care routine!

Great conditioner I love this brand because it makes your hair feel so soft once you’re done using it. I highly recommend that you try it for yourself. It’s pretty pricey but if you get the right size it’s kinda worth the money you spend.

Bueno, pero no cumplió todas mis expectativas
El acondicionador tiene una textura agradable y ayuda a que el cabello se sienta más suave después del lavado. Sin embargo, por el precio esperaba mejores resultados en la protección y reparación del daño. Noté algo de hidratación, pero no una diferencia significativa en comparación con otros productos más económicos. No es un mal producto, pero tampoco me impresionó lo suficiente como para volver a comprarlo.

Not Worth the Hype or Price
I’ve used high-end products for over 20 years now (Unite, Joico, etc.) and decided it was time to switch it up a bit. So far I’ve used this K18 conditioner twice and it makes my hair feel like straw. To me, this is no different than products found in a local drugstore. It’s not necessarily bad - but it’s not good and definitely not worth the price tag.

Made my hair very greasy feeling.
I did not care for this conditioner at all. I rinsed my hair thoroughly and felt like my hair still had an oily feeling after using it. The day after washing my hair, it was so oily and looked like it had not been washed in several days. My hair was very greasy and I am definitely not a fan.

Awful. This paired with the shampoo caused massive amounts of hair shedding. I’m talking clumps of hair. Once I stopped and went back to my usual shampoo the hair fall stopped
