Though I used less quantity mentioned on the description . it makes my hair little dry but dryness goes away when I use leave in conditioner and avocado oil after 30 mins. Hair feel stronger and softer. I dont know if it is okay not to use it on the 2nd wash. I posted question asking that. if I dont get answer I will use remaining product after one month. it is hella expensive. but it works with so little amount. So I will use 5ml as expensive spa once in a month.

Hope this answers your question! **Q: How often should this be used?** A: We recommend starting with the "repair phase" and using K18 4-6 times in a row. Then once your hair is feeling improved you can switch to the "maintenance phase" and use K18 every 3-4 shampoos. If you love the way K18 makes your hair feel you can use it every shampoo if you wish! **Q: Should I use this before or after applying Demi permanent hair dye?** A: Hi There! If you are only using the mask, you would use it after the Demi Permanent Dye. Apply your color, process, shampoo, skip conditioner, towel dry, add the mask, wait 4 mins and style as usual. Hope this answers your question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Really impressed with the product *by A***I on 17 March 2024* This product give result on 1st use.
