Actually worth the price
Okay, I’ll admit it, I was skeptical. A tiny 15ml bottle promising to reverse years of hair damage? For that price? Felt like one of those “trust me bro” moments. But hear me out: this little tube is magic in disguise. First of all, it’s not your typical slap-it-on-and-rinse-it-out hair mask. Nope. K18 is a leave-in treatment, and you only need a pea-sized amount (seriously, don’t get greedy). After shampooing (no conditioner!), towel-dry your hair, apply evenly from mid-length to ends, wait 4 minutes for the science-y peptides to do their thing, and then style like usual. No rinsing. I used K18 for four to six washes in a row. And then switch to maintenance mode and use as needed. Here’s the part that made me do a double take: after just one use, my hair felt smoother, bouncier, and somehow healthier. Like, salon-visit-level healthier. It’s like it filled in the emotional damage too. Yes, it’s on the pricier side, especially for just 15ml. But here’s the deal: it’s packed with patented tech that actually repairs hair from the inside out (not just coating it with silicones). So you’re paying for results, not just fancy packaging. And since you don’t need much, this little tube goes a long way. Final verdict? If your hair’s been through bleach, heat, or a rough breakup? it deserves this.

This is magic in a bottle
I dyed my hair a lot and use heat almost daily! This saved my hair from the first use! I use leave in conditioner, serum, and heat protection spray after 5 minutes of applying this and my hair felt so soft

It is quite pricy but does the job
The product is good, however it is way too pricy for its quantity. Another point to consider is that they say on the instructions to leave it for 4 minutes before styling to get proper results! For me I need to leave it for 30 minutes at least prior to hair drying/styling my hair to get the required result. Another note is that this is not an anti-frizz treatment for humid weather so don't expect much as well on that matter.

Es muy caro para la cantidad de producto que viene pero merece la pena. He sufrido varios crímenes contra mi pelo este año y me está ayudando a recuperar el buen aspecto. Una vez que el pelo está estropeado es difícil repararlo pero al menos si que aparenta más sano. Lo recomiendo.

Second purchase now, and is impressive when using and left in hair as recommended. Styles well, and leaves hair soft and silky as opposed dry and bushy. However, the next day you would never know, so undecided if would purchase again a third time.

This product is actually worth the price. You can see improvement in your hair from the first application and it keeps getting better each time. My hair feels like it used to feel when I was young. Shiny and smooth. Very satisfied. Will buy again.
