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. Review: Saving My Damaged Hair!!! - This hair mask works wonders if you’re trying to restore damaged hair! I had really bad split ends that kept breaking off, to the point where my hair was actually getting shorter. It was honestly making me so sad because I was trying to grow my hair out but couldn’t get ahead of the breakage. I tried several cheaper, store-brand hair masks first because I didn’t want to spend the money on K18, but none of them were really helping. I finally gave in and purchased it, and I’m so glad I did. Even though the bottle is only 1.7 fl oz, a little goes a long way, and my hair feels noticeably stronger and more bonded for days between washes. If you have a lot of hair, you may need 3–4 pumps or more, so this could definitely become a recurring purchase. It is pricey for such a small bottle, but if you’re dealing with damaged hair and constant breakage, I think it’s worth giving K18 a chance. I’m really happy I finally did! ## 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 | B0961ZS96M | | Active Ingredients | Water (Aqua) (Eau), Alcohol Denat., PropyleneGlycol, Cetearyl Alcohol, Dicaprylyl Ether, Cetyl Esters, BehentrimoniumChloride, Polysorbate 20, sh-Oligopeptide-78, Hydrolyzed Wheat Protein,Hydrolyzed Wheat Starch, Isopropyl Alcohol, Tocopherol, Phenoxyethanol,Potassium Sorbate, Citric Acid, Fragrance (Parfum), Geraniol, Linalool, HexylCinnamal, Benzyl Alcohol. | | Additional Features | Travel Size | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #111 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 31,781 Reviews | | Global Trade Identification Number | 00858511001128 | | Hair Conditioner Type | Leave-In Hair Conditioner | | Hair Type | Damaged | | Item Dimensions | 1.87 x 1.87 x 4 inches | | Item Form | Cream | | Item Weight | 3.2 ounces | | Liquid Volume | 50 ml | | Manufacturer | K18 | | Manufacturer Part Number | K18-31005 | | Material Feature | Natural | | Material Features | Natural | | Model Number | K18-31005 | | 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 ### ⭐⭐⭐⭐⭐ Worth it when you know what you’re buying *by A***R on August 22, 2026* Amazing, please read.

My hair was so damaged by a crap straightener I never thought it would look healthy again. Don’t expect immediate results. It took 2 weeks of applying every day to have it soft and to begin showing signs of repair. I also suggest getting a good leave in conditioner that is light weight. Yes it is expensive but honestly I only use very little at a time. I don’t mind buying because it lasts a long time and I’m not wasting my money on products that don’t work. If you have damaged hair I promise this will work. ## Frequently Bought Together - K18 Leave-In Molecular Hair Mask, Repairs Dry or Damaged Hair, Reverse Hair Damage from Bleach, Color, Chemical Services & Heat - K18 Damage Shield Protective Conditioner, Protects Hair from Daily Damage, Improves Strength & Shine, 8.5 Fl Oz - K18 Damage Shield Protective Shampoo, Reduces Frizziness & Tangles, Maintains Hair Health, 8.5 Fl Oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/328478736-leave-in-molecular-repair-hair-mask](https://www.desertcart.com.pa/products/328478736-leave-in-molecular-repair-hair-mask) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-08-31*
