Love you k18


Great for highlighted hair, my hair shines and great heat protection when using hair straighteners, will definitely purchase again

Game changer

I have been using this oil for about 6weeks and apply it four minutes before I blow dry my hair , the condition of my hair has improved dramatically, feeling so much smoother and no dry ends. I would highly recommend this product , well worth the high price as you most definitely will get results!

Frizz free!!!

I use the k18 mask plus the oil. Adding in the oil has been an absolute game changer! It really does get rid of the frizz. I apply it when my hair is wet and It left my hair silky smooth and so shiny. I finish my style with adding a very small amount of the oil just to smooth away any flyaway. I have a full head of highlights so these 2 products are absolutely necessary for my hair. Also love that it's a heat protectant too! Do yourselves a favour and buy this oil😍

Little goes along way

My hair is so fine and thin.
This oil is truly weightless on it & gives it a great shine! Absolutely unreal! Dont think I could go back from k18
