Review: This works if you actually need it. - I think alot of people use K18 without understanding if they need it or who it is for. My hair at one time felt really dry and I asked my hairdresser about K18 and she stated that I did not need it K18 and is it is a product designed for damaged hair. Another occasion I had really bad heat damage on my side fringe caused by a combination of bleach and GHD's. It couldn't be cut out because of where it was and it would have looked odd. At that point I was advised to use K18. A little goes a really long way. It is also not designed to be used for an extended period with every wash. It is a treatment. If you do not apply it correctly then it will not worked. If you apply it without towel drying your hair or if you have used a conditioner beforehand it will not work. The conditioner prevents K18 from penetrating the hair and doing it's job. When I applied it to my very frazzled side fringe within a few uses it had significantly reversed the damage. I have found it has done more for my hair than Olaplex, even though they do very different things. K18 fixes my hair far more effectively than Olaplex has ever prevented any damage from bleaching. If you overuse this product or use it when you don't need it then it will actually make the condition of your hair worse. It is very expensive but it is only supposed to be used to reverse the damage then you should stop using it. If your hair is in a worse condition, then it is likely you didn't need it and if it hasn't done anything its possible you haven't used it correctly. Also desertcart is an official stockist of K18 so as long you haven't purchased it from a seller that isn't K18 then you will get a legitimate product. In short, it's pricey but effective as long as you use it right and actually need it.
Review: Great product - Product is great for my hair as it is very dry and broken

## Questions & Answers

**Q: Hi folks do you put this on to dry hair or damp hair? 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. Hope this helped x
