Great conditioner
This conditioner is a great product. It helps with my hair that is very over processed I use it daily. My hair does not feel dry and brittle. It is soft and full. I really recommend this product to anyone with processed hair.

Excellent Conditioner
This stuff is great! It really moisturizes my hair and leaves it soft and easy to comb. Smells nice, too. Highly recommend for dry, color-treated hair. It's a little pricey, but worth every penny.

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.

Great product. Crappy pumps.
Love this shampoo and conditioner. It’s great on my hair and I am so glad to find it in a large pump bottle. My only complaint is that the pumps rarely work.

Gamechanger!
Ich habe für ein Echthaar-Haarteil ewig einen Conditioner oder eine Haarkur gesucht, welches die Haare wirklich weicher macht. Echthaar-Teile tendieren dazu sehr schnell stohig zu werden und zu brechen, egal, wie gut man sie pflegt. Die unteren 5-10cm knoten immer zusammen und stehe fast steif ab. Alles versucht. Dies ist die erste Spülung, die echt einen Unterschied macht. Die Haare sind danach deutlich weicher und nicht mehr so trocken. Das Peodukt ist zwar teurer, aber egiebiger als andere und es macht wirklich einen Unterschied. Mitttlerweile legw ich das Haarteil nur noch in eine Schüssel mit warmem Wasser und einigen Spritzern des Produkts - Perfekt. Und es beschwert die Haare nicht und lässt sie nicht schmiwrig aussehen, wie bei andwren reichaltigen Produkten. 10/10!

This is not just good….it’s frickin AMAZING! The first use was incredible, my hair in 67yrs has never been this fantastic! I can’t stop putting my hands through my hair, it’s just so soft and smooth. Literally lost for words, this product does what it advertises! The best conditioner ever, will never stop using it! Will definitely get more of their products, can’t wait to try the dry shampoo. Thanks K18… best products on the market, no planet!❤️❤️❤️❤️❤️
