I have blonde hair (not natural) and it can get very dry. I notice a different even after one use. Having used it for a while now it has made a massive difference to my hair. It feels soft and strong. I suffer from a lot of hair loss and it has also helped with this greatly. I don't have near as much breakage so it works well and does exactly what it says it does. It is a small tube but it goes a long way . It is a bit expensive but I believe it's worth every penny. Review: Improved hair health and appearance - I bought the 5ml sample size which was perfect - though it looks tiny it has lasted six applications for my shoulder-blade length, medium thickness, bleach damaged, heat-treated, perimenopausal hair. I had noticed a lot of breakage, especially near my crown. My hair always felt frazzled at the ends and just didn't look shiny or healthy. I used Head and Shoulders clarifying shampoo then K18 for six consecutive washes, followed by Redken Extreme Length leave in conditioner. You have to wait four minutes once you've applied the K18 then style as usual (no need to wash out). It's simple to use in the shower routine and adds no extra time - in fact it saves time as you don't need to use conditioner afterwards. My hair felt softer and healthier after each use and others have complimented my hair. It's not got any particular wow factor after one wash but my hair is now 100% in better condition. Broken ends are smoother and less noticeable, my hair looks so much shinier, fuller and healthier. I'll have a rest from this now but probably do another six washes after my next lightening session to maintain strength and health. ## Features - K18 Leave-In Repair Hair Mask Treatment to Repair Dry or Damaged Hair - 4 Minutes to Reverse Hair Damage from Bleach, Color, Chemical Services and Heat - An At-home Leave-In Treatment infused with the patented K18Peptide that renews hair to its most youthful, healthy state.

Thank you 😊** A: You shampoo and towel dry your hair, a clarifying shampoo if you have (do not use conditioner). Then apply 1-5ml depending on hair length, working into more damaged areas mid lengths and ends, comb through. Leave for 4 minutes and then style as usual (you can then add all your usual styling products). Hope this explains. Thanks TheHairShop **Q: I'd like to know the cost to the UK - don't understand the tax and import implications but don't want any surprises!** A: I understand you are in UK Goods in UK - No extra cost or import implications **Q: Can I use this product without hair drying my hair afterwards? Can it also be used with the bowl method for my wavy hair?** A: Hi The K18 Leave-In Repair Hair Mask is designed to be used as a leave-in treatment, so you don't necessarily need to dry your hair afterwards. It's meant to be applied to damp or towel-dried hair and left in without rinsing. You can simply apply the product and let your hair air dry naturally. As for using the bowl method with the K18 mask, the bowl method is typically used for deep conditioning treatments, where the hair is saturated with a conditioner or mask and then covered with a shower cap or plastic wrap to enhance absorption. While the K18 mask is not specifically intended for the bowl method, you can certainly try it if you prefer that method. However, keep in mind that the K18 mask is formulated as a leave-in treatment, so it may not have the same effect when used with the bowl method compared to traditional rinse-out masks. It's always a good idea to follow the instructions provided by the manufacturer for the best results. Have a great weekend! **Q: Does it weight the hair down? And makes it flat like a keratin treatment does it?** A: Not at all don’t apply too much, where is your hair damaged the most? Apply it there and brush through! It’s the best thing I’ve ever bought for my extremely damaged coloured fine brittle hair! Buy the small 5ml to try if your not sure. I got 3-4 uses from that tube.

I continued as directed for a further 5 washes and all was good. I intended to do as directed and use it as maintenance every 3rd wash . But the very first hairwash without it made my hair return to the frizzy mess it was before. I surmise that the effect of this product is only valid whilst it is in use after every wash and that the effect is simply a temporary fix. Extremely disappointing considering all the hype and the vastly overpriced cost of the product. ## Frequently Bought Together - K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask, 5 ml - Olaplex No. 3 Hair Perfector Repairing Hair Treatment, Concentrated for Dry Damaged Hair, Repairs & Strengthens All Hair Types, 100ml --- ## 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.vu/products/365126853-k18-biomimetic-hairscience-leave-in-molecular-repair-hair-mask-5](https://www.desertcart.vu/products/365126853-k18-biomimetic-hairscience-leave-in-molecular-repair-hair-mask-5) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-17*
