Amazon Has A Hidden Section For Cult-Fave Products — Here Are The 34 Best On It This Week

K18 is a small business that specializes in hair products. 

To use, wash your hair with shampoo and not conditioner. Towel dry your hair and apply the hair mask, leaving it for four minutes. Then style as usual without rinsing. 

Here’s what BuzzFeeder Melanie Aman says about it: “I bleach my dark brown-black Asian hair blonde every 6–8 weeks, so I was immediately intrigued when I first heard some stylists at my salon raving about K18. I was gobsmacked at how much softer my hair was. Seriously. I spent the whole day touching my hair, and even my boyfriend agreed that my mane was noticeably silkier. Olaplex was my go-to before I tried K18 and I still stand by it as a product, but I really love that K18 is a leave-in treatment rather than an in-shower mask. Having to let the Olaplex sit for 10 minutes felt like forever, especially when I wasn’t taking an everything shower (you know, the ones where you exfoliate and shave). With K18, you let it sit in your hair for four minutes post shower to activate and then you can style your hair (or just let it air dry like I do). I’ve found that my hair is softest the next day, so don’t be discouraged if your hair looks or feels the same the day you use it.”

Promising review: “My hair stylist recommended this product for my hair and it was such a superior product to anything else I have used. It is expensive and I have long hair so it is doubly expensive, but so worth it. As I aged my hair became really frizzy and dry, but this product changed everything, leaving my hair so manageable, silky, soft, body and no frizz. I cannot say enough good things about K18.” —Dawne
