See why BuzzFeed editor Melanie Aman loves this treatment: “I bleach my dark brown-black Asian hair blonde every six to eight weeks, so when I first heard some stylists at my salon raving about K18, I was immediately intrigued. And it turns out the rest of the world loves it too, because the first time I tried to buy it, it was sold out at Sephora. I finally grabbed a bottle and was speechless at how much softer my hair was. Seriously. I spent the entire day touching my hair and even my boyfriend thought my mane was noticeably silkier.
Olaplex was my favorite before I tried K18, and I still stand behind that product, but I really love that K18 is a leave-in treatment and not a shower mask. Leaving Olaplex on for 10 minutes felt like an eternity, especially if I didn’t take an all-around shower (you know, the ones where you exfoliate and shave). With K18, you leave it in your hair for four minutes after you shower to activate it, and then you can style your hair (or just let it air dry, like I do).
I found that my hair is the softest next day, so don’t be discouraged if your hair looks or feels the same on the day of application. One last thing: it is quite expensive, but a small amount is enough. The 50 ml tube I bought lasted several months, and finally, K18 can become a maintenance product, so you don’t have to use it every time you wash your hair.”
Promising review: “My hairdresser used this on my hair and it made it instantly silky. I decided to buy it because I’m 52 and my hair has had a different, frizzier texture over the past few years. I have been using it for several months now and I can say that it works really well. It’s expensive, but I don’t wash my hair every day, so it’s lasted a while. It seems to repair damage like it promises.” —AW
