It works perfectly
This product, with K18 Leave-In Molecular Hair Mask, Repairs Dry or Damaged Hair, Reverse Hair Damage from Bleach, Color, Chemical Services & Heat, helped me get my wavy hair looking and feeling soft after being extremely dry due to colouring with a non chemical hair colour product. It took several weeks but considering how my hair was, it was magic. Plus, I have no problem with my sensitive scalp.

GREAT product!!
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.

Bought this for my wife and she loves it. She was having problems with breakage and flyaways, but now she’s loving the way her hair looks and feels.

LOVE
I have always hated Olaplex after I found k18. super expensive but definitely worth it. I took a star away only because of how small this $30 bottle is. Very tiny
Isabella –
Overpriced and useless
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 thatâs in the droplet for each use, and even at that, I feel nothing. My hair doesnât feel any different, and thereâs 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.

Great product for fine hair
I have fine thin hair and this works great. I use 2-3 drops and leaves my hair shiny and soft without feeling or looking oily

Small K18 Hair
Make sure to look at the OZ before purchase. This is a tiny bottle and pretty expensive for the amount provided. Scent is light and not greasy. I have long thick hair so it doesn’t go a long way.

But worth it! Doesnât leave my hair greasy. I use about 3 drops in my ends – will last a long time!

Ich habe schon einige Haaröle getestet, darunter Olaplex, Hairlust, Gisou, ⦠aber ich muss sagen, dass das Ãl von K18 für mich am besten funktioniert.Die Konsistenz ist etwas flüssiger als man erwartet, dadurch ist es aber sehr leicht im Haar und hinterlässt keine fettig-aussehenden Stellen.Es ist sehr ergiebig und sein Geld auf jeden Fall wert.
