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 | | ASIN | B09HR5KSR8 | | Age Range Description | Adult | | Best Sellers Rank | #192 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #1 in Hair Treatment Masks | | Brand Name | K18 | | Customer Reviews | 4.3 4.3 out of 5 stars (32,714) | | 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 | | Item model number | K18-31007 | | Liquid Volume | 15 cubic_meters | | Manufacturer | K18 | | Manufacturer | K18 | | Manufacturer Part Number | K18-31007 | | 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 Dimensions | 1.37 x 1.37 x 3.18 inches; 1.76 ounces | | 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. ## 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.co.za/products/383765053-leave-in-molecular-repair-hair-mask](https://www.desertcart.co.za/products/383765053-leave-in-molecular-repair-hair-mask) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-11*
