K18 Leave-In Molecular Hair Mask, Repairs Dry or Damaged Hair, Reverse Hair Damage from Bleach, Color, Chemical Services & Heat

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!

The reason I bought this product. My hair designer suggested this to help with senior dry hair. 1. Easy to read instructions for applying. 2. Make hair soft and smooth. 3. One pump for thin/fine hair. 2 pumps for thick hair. 4. Scent is nice. 5. It’s on the expensive side but it’s worth the price for healthier hair in the long run.

LITERALLY SAVED MY HAIR IN ONE USE – MIRACLE IN A BOTTLE I 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.

Very different from other hair masks.. I have a Bob cut which I’m trying to grow out. I followed directions and waited four minutes, combed it and left it alone. I always air dry my hair. After it was on, I felt my damp hair and it seemed like there was too much stuff on, like a thick texture. But when it was dry it felt soft, most definitely tamed frizz and encouraged my waves and some curls. It’s expensive, but I will probably use once a week. Try it if your hair needs help.

I really like this hair mask. I think it works well for chemically treated hair. It makes my hair soft. I will say the bottle is very small for the price. You don't get very much. I would like to see a better value for my money.

Magical. They put so much R&D into their products and I can see that in full force when using anything from the K18 line. Really incredible - makes my hair so smooth and removes any tangles. It takes time to get used to skipping conditioner in the shower (which you must skip to use this) but my results have been great so I’ll continue to do so every time I use this treatment. I use it about 4-6 times a month. I would love if this had a nice scent to it or if it was completely scentless but it’s fine as it is - doesn’t have a bad scent. I’ve been using this for more than 6 months…No weird reactions - each application has worked well!

I know it says 'mini' but for 30$ I thought the product would be a little bigger. It has an unpleasant smell. It did leave my ends feeling conditioned but you could probably get similar results with cheaper products. Not mad I bought it, but probably wouldn't purchase twice.

Full disclosure: I don't have damaged hair. I'm an older woman with natural very light blonde hair. I don't color it or use heat on it. I thought it was healthy-ish. I heard about K18 being a miracle product for damage, so I thought I'd see what it can do for me. When I tell you I had no idea my hair could look so good! I'm stunned. My hair looks twice as full, shiny, soft and just amazing. Yes it's really expensive and yes I'm going to be a regular buyer.

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.

fortalece bastante. com certeza vou comprar de novo.
