A product that does what it says ! WOW!!! First time using it, the next morning it was like I had a totally different head of hair ! Soft, Shiny, Bouncy, Healthy ! I curl my hair with a curling iron and my hair even held the curls better !! Expensive? Yes! But Worth It !!😁 Review: Worth it when you know what you’re buying - Amazing, please read. I never leave detailed reviews on products but I have to for this. In the last 7 days I attempted to remove purple dye including ion semi permanent color and Arctic Fox Purple AF out of my hair that I had been using for over 6 months. I used two different color removers including Color Oops, two different brunette dyes and bleach. Yes bleach, all within the last 7 days. Needless to say my hair is extremely damaged but less so after using this K18 product only once this evening. First off I would like to comment on the price and the amount of product you are getting I think people are not understanding what this product actually is. It is not meant to be repurchased several times back to back by the company, this is a mask treatment that is very concentrated and has specific directions on how to use. (Apply to towel dry hair after shampoo ONLY no conditioner should be used in the shower, apply only a couple of pumps and wait 4 minutes before drying) repeat this process for 3-4 washes for maximum results (although I saw noticeable results my first use) You are essentially buying a very concentrated formula that is designed to be used like the above the directions (not some ongoing product designed to be applied daily) that is why the price is so high! There is no need to have this product in a huge quantity because it simply isn’t needed, the bottle and price are actually appropriately priced (objectively we would like prices to be low as possible I know) but this is high-end salon quality result K18 is known to deliver which why their prices are generally pricier than drugstore. Bottom line: in my experience it is worth it knowing the damage my hair was under and knowing the concentrated formula designed to be used under specific directions (think of a spot treatment, not long-term) My hair is noticeably more manageable, significantly softer and smoother with less noticeable flyaways and less obvious signs of damage and this is being said with just one application. ## Features - 4-Minute Molecular Hair Repair Treatment: A leave-in peptide hair mask designed to repair and reverse damage at the molecular level for stronger, smoother, more resilient hair in just 4 minutes. - How It Works: Patented K18PEPTIDE repairs hair at a molecular level to reverse damage from bleach, color, chemical services, and heat*. The biotech-developed peptide mimics and clicks into hair's keratin structure to reconnect polypeptide chains and disulfide bonds for strength along the length + width of hair. - Works on All Hair Types: Because our hair treatment works at the innermost layer of the hair rather than only targeting the outer cuticle like many deep conditioning hair masks, it's effective on all strands, even coily and curly hair. - Boosts Strength + Smoothness: Helps improve texture, manageability, and bounce with a highly concentrated hair cream formula with detangling and softening benefits. Most see results after 2-3 uses. - How to Use: Shampoo, skip conditioner, and apply 1-3 pumps of the leave in hair mask to clean, towel-dried hair. Let sit for 4 minutes, do not rinse, then style as usual. Use for 4-6 consecutive washes, then as needed. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09HR5KSR8 | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #249 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #1 in Hair Treatment Masks | | Brand | K18 | | Brand Name | K18 | | Customer Reviews | 4.3 out of 5 stars 32,696 Reviews | | Global Trade Identification Number | 00858511001289 | | Hair Conditioner Type | Hair Conditioning Mask | | Hair Type | Chemically Treated | | Item Dimensions | 1.37 x 1.37 x 3.18 inches | | Item Form | Cream | | Item Highlight | Peptide Hair Treatment Mask Repairs Bleach, Color, Chemical Services, Heat Damage In 4 Minutes | | Item Weight | 0.05 kg | | Liquid Volume | 15 cubic_meters | | Manufacturer | K18 | | Manufacturer Part Number | K18-31007 | | Material Feature | Cruelty Free | | Material Features | Cruelty Free | | Model Number | K18-31007 | | Number of Items | 1 | | Package Type Name | Jar | | Product Benefits | "Real, lasting repair powered by K18PEPTIDE™ Hair like new in 4 minutes* Soft, strong, bouncy hair for everyone " Product Benefits "Real, lasting repair powered by K18PEPTIDE™ Hair like new in 4 minutes* Soft, strong, bouncy hair for everyone " See more | | Recommended Uses For Product | Shampoo, skip conditioner.

It’s powered by our biomimetic K18PEPTIDE to seamlessly fit in and reconnect broken polypeptide chains at the molecular level. **Q: What is the K18PEPTIDE?** A: K18PEPTIDE is a biotech-developed peptide that mimics hair’s structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during damage from bleach + color, chemical services, and heat. **Q: Why skip conditioner?** A: Conditioner leaves a film that blocks our peptide from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner, a leave-in, or any type of product. **Q: I noticed there’s alcohol in the formula, isn’t that bad for you?** A: We like to keep our formulas minimal, only using the exact amount of ingredients needed to get the peptide where it needs to go. Here the alcohol serves as an agent to optimize the hair environment for the K18 Mask to work on a deeper level. **Q: When should I expect to see results?** A: Most see results after 2-3 uses. The more damaged the hair, the more dramatic the results so it may vary depending on your hair type and level of damage. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It Really Works *by A***R on October 7, 2026* FINALLY !!!!

OMG ! OMG! K-18 FULFILLS ITS CLAIMS Read on! *by G***G on June 25, 2025* I’m over 55 and have spent decades trying everything — from $9 to $144 per product — hoping for softer, healthier hair. I have 3a curls hidden under years of color, heat damage, and dryness. My hair would break and frizz so badly it looked like I had layers (I don’t). K18 is the first and only product that actually delivered on its promise to repair — not just coat — my hair. I was fully prepared to return this if it did not make a difference. It did. This isn’t a conditioner or mask. K18 uses a patented technology that works from the inside out. I used a clarifying shampoo, applied 6 pumps (very small pumps from the "try it" bottle!), finger-raked it through damp hair, waited 4 minutes, and then combed through. No rinsing, no other products. I let my hair air-dry, and it already felt softer and smoother with significantly less frizz. No fragrance -makes me happy. Important note: You do not need to rub this aggressively between your palms to "activate" it — that’s a common myth. Just rub your palms lightly so you can apply it evenly and let the science do the work. It works on the keratin molecules to repair your hair from the inside out. Friction is not going to make the molecules smaller. Don't know why people start these rumors. The next morning, I used my straightener on medium heat and was stunned. Instead of the usual dry straw, my hair was sleek, shiny, and bouncy. Even the ends curled beautifully — something I’ve never seen on my hair before. After four treatments, my hair now feels different, although the greatest results came after the very first use. My hair is softer, smoother, more manageable, with less frizz and more shine. Even in Florida’s 90°+ heat and humidity, it holds up — and I’m not using anything else but K18. A friend even asked to try it after seeing my results. It’s expensive, but absolutely worth it. I’ve already bought the larger bottle. I’m sticking with K18 — this changed everything for me. And to address the expense, the 50mL pump provides 50 pumps. That's 25 applications for me. My average thickness, long hair uses 2 full regular pumps. After the first 4 applications, you move to every 4 washes. That means after the first four treatments, I have 21 treatments more still in the pump bottle. For me, with super dry hair, that means it will last another 18-21 weeks since I only wash once a week, and an occasional "extra". I am going to guess I have taken at least $100 of products that did not work for me to the women's shelter over that time, meaning the waste was as much as this effective product that takes no time to use, packs easily in a suitcase, doesn't stink and IT WORKS! If you have super straight, silky hair, like Asian hair, or other non-porous hair, I do not think you are going to get the same results. You probably already have the kind of hair those of us with porous, damaged hair are looking for.
