For best results, use for the first 4-6 consecutive washes following a service, and then every 3-4 washes as needed to maintain hair strength.

The product itself is great, very little amount of this product goes a long way. It leaves your hair very soft once it dries. I was more surprised with the shipping. I love how this was delivered so quickly. 🙂

I have naturally curly, dry, frizzy hair. After using K18 once my hair feels so soft, healthy and more manageable. I’d say there’s a little less frizz. Looking forward to seeing the results after more use.

My hair feels softer, split ends are less visible, and frizziness is diminished. I’ve noticed a bigger change with k18 than Olaplex. Couldn’t recommend more !!

So good. My hair has dry blonde ends and this product has smoothed them without them being overly coated like some conditioners with tons of silicon can do. Very natural. Hair looks healthy. Will repurchase.

Forget Olaplex this stuff is INCREDIBLE. I have fine curly hair, which has been bleached a few times over the past couple of years and this product makes it feel like silk. It makes my curls so nice and defined and the glossiness of my hair improved drastically after the first use!!! Highly recommend, a staple in my hair care!

k18 hair treatment is the Best, 10/10 from me! I have only to apply it to damp hair , leave 4 minutes and style.
Usually style daily with flat irons but once I have blow waved, straightened, I am good for a week.
Great product from a great company.
Fast , efficient and friendly.

Superstar product – this has kept my bleached hair so soft and healthy. Highly recommend for hair new to bleaching – was a bit worried about running out too quickly but you only need 1 – ½ pumps and it provides great coverage.
