Worth the hype!
This product transformed my hair which were extremely dry and damaged. I just shampoo and don't use conditioner. Instead towel dry my hair and run the product through for visibly shiny hair
Report this reviewNot sure
I wanted so much to try this, so glad that it was in the Advent Calendar. I have very dry bleached hair so always do a lot of treatments for reconstruction. Â Followed the instructions, my hair felt thicker but no wow effect. This is not hydrating and reparative enough for my type of hair.
Report this reviewI don’t know yet
My hair gets dry in the winter weather and using K18… because you can’t use any products other than shampoo. I’m on the fence, don’t know if it actually improved my hairÂ
Report this reviewI love it
I have hair below shoulders. I use several times a week, often every day. A year has passed and I have not finished this product yet, although I have already bought two jars on top. Adore!
Report this reviewWorks Wonders
I bought this products a couple of weeks ago in a smaller container, the product works really well and gives my hair a soft and shiny finish. It looks healthier than before. This packaging is much better than the smaller one, it was more difficult to get all the product out. The use of this pump is much easier.
Report this reviewLoved it!
This product really gives my hair a nice, silky feeling. Only downside of this product is it's packaging. It's really difficult to get everything out and it's a bit pricy. I will be buying this product again but in another size.

Was really sceptic about this product but it did everything it claimed to do. Recommended!Â
Report this reviewChanged my hair for the better.
Really love this. I find you have to rub it together in your palms to get it to work best.
