    K18 excellent product
    I am truly impressed with the K18 Leave-In Molecular Repair Hair Mask. After just a few uses, I noticed a dramatic difference in the strength and smoothness of my hair. It brought life back to my ends, reduced frizz, and made my hair feel softer than it has in years. I love that it works quickly and doesn’t require rinsing — just apply and let it do its magic. If your hair is damaged, dry, or over-processed, this product is absolutely worth it. Highly recommended!

    Is there are any more to be said than what’s been said already?
    Because of the insane price, I put off buying the full size until I had used the trial size and knew it was worth my money.It is!!I did the 6 consecutive treatments, followed by one approximately every 4-6 weeks, and the health of my hair has improved dramatically.I had some troubleshooting errors originally, as having thick, long, curly hair makes it almost impossible to not use a conditioner.However, after about 4 uses and a lot of research, I started to wait the 4 minutes and follow up with a conditioner, and that’s when I felt my hair start to feel amazing.The damage is reduced, there is significantly less breakage and shedding, and I am looking to buy the jumbo size once this is finished.It is now a staple in my routine despite the cost simply because of the effectiveness.

    Fixed My Bleached Hair in One Use – Actual Hair Resurrection
    LITERALLY SAVED MY HAIR IN ONE USE – MIRACLE IN A BOTTLEI don’t usually leave reviews, but I would actually fight someone over this product if it ever got discontinued. Like. That’s how serious I am. I bleached the living life out of my hair recently—think straw, think crunchy ramen noodle ends, think “oops I fried it but I still want it to look good.” I used K18 once, and I swear to god my hair looked like I had never damaged it at all. ONE USE. Not three. Not six. One.This isn’t your average deep conditioner or protein mask. This is full-on biotech magic. The science behind it is real—this isn’t marketing fluff. It uses a patented peptide (K18Peptide™) that literally reconnects broken polypeptide chains in your hair. Like, it doesn’t just make your hair feel soft temporarily. It rebuilds it. We’re talking actual molecular repair. You feel the difference IMMEDIATELY. And even better? The results just get better the more you use it.No rinsing, no long routines. You just shampoo, skip conditioner, towel-dry, use 1–3 pumps depending on your hair length, and then wait 4 minutes. THAT’S IT. It absorbs fast, isn’t heavy, doesn’t make your roots oily, and doesn’t coat your hair in a waxy film like other products. My hair went from stringy and dead to soft, bouncy, shiny, and fully alive again.Also? A little goes a long way. It’s expensive, yeah, but it lasts forever and genuinely does what it says. I’d rather spend money once on something that works than keep buying cheap products that do nothing but mask the damage.TL;DR – If your hair is damaged from bleach, color, heat, or just life, BUY THIS. It’s not hype. It’s not overrated. It’s the best hair product on the planet and deserves to be in every single “best of” list forever. I’ve tried Olaplex, I’ve tried everything—nothing touches this. K18 is THAT GIRL.

    Pricey!!! But seems to work after only one use!
    Not using conditioner when my hair is so damaged seemed crazy! I usually put quite a bit of conditioner on my hair to be able to comb through it.I bought the bigger size and it’s REALLY small for the price. I saved a little money by choosing “subscribe and save” $67.50 instead of $75. I used the shampoo, 3 pumps of this & 4 drops of the oil. Surprisingly with only 3 pumps I was able to get my brush through easily! It didn’t look like enough. Nor did my hair instantly feel smooth when applying. So definitely wait the 4 minutes before combing it through.My hair is fairly thick, about 1/2 way down my back and I recently bleached it from my natural brown to blond. I bought the shampoo/ conditioner & oil. My hair is so damaged after bleaching it. 🙁 I’ve tried several recommendations to get it healthy again. Mondo & others haven’t worked. So I was up to try this!It felt softer after using it for the first time! There isn’t much scent and my hair isn’t greasy. I’ll use it 4-6 more times and hopefully my hair will look much healthier as promised. I live where it’s fairly humid. If this works well for that, it’ll be worth it!Update 9/8/25: It’s really great!!! this brand has saved my hair! I especially love using this “conditioner” after rising my hair from swimming at the waterpark. I don’t use this every time I wash my hair bc it’s just too expensive for my long hair. But I bought the regular conditioner and I finally have healthier looking hair again after frying it, by coloring it blonde (with bleach) a few times.

    A little goes a long way!
    I have very dark hair naturally and I decided to go light blonde, close to platinum, so I can color over it with a lighter ash blonde. I bleached my hair twice, did a toner treatment, and then bleached it again a week later and toned it again and colored it. It was rough on my hair for sure. This serum is amazing! I used it as instructed for two days in a row (so far, I will use it 4 more times in a row as instructed) and my hair is soft and already feels stronger and looks healthier. It seemed expensive at first for the amount of product but it was well worth it! It doesn’t take much, I used 3 pumps total and worked it though my hair and my hair was smooth and super moisturized. The ingredients are cruelty free too which is a win for me! I highly recommend this product for bleached or color treated hair that is frail, dry, over processed, and otherwise chemically damaged.

    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.
