## Description

K18 Leave-In Repair Hair Mask, 0.17 Fl Oz - 5 ml : desertcart.in: Beauty

Review: Really impressed with the product - This product give result on 1st use. 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.

## Questions & Answers

**Q: Is the mask a single application in the tube?**
A: When you use K18 mask you only use 1-3ml per treatment so most get 2-3 uses.

**Q: Does this product contain sulfates?**
A: Hi There!   K18 is free of Parabens; Sulfates, Silicones, Phthalates, Sodium Chloride, Artificial Colors Formaldehyde and Formaldehyde Donors.  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.
