Q: Is the mask a single application in the tube?

When you use K18 mask you only use 1-3ml per treatment so most get 2-3 uses.

Q: Does this product contain sulfates?

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?

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?

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.
