## 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
