not worth it
the K18 mask is amazing. However, the volume spray was useless, I did not see a noticeable difference to justify the price, and it made my hair feel disgusting, it was rough and lacked shine after using the spray.

A let down
So disappointed, the repair treatment makes my hair greasy and I purposely try not to use too much. I've heard you can use it as normal and wait 4 minutes then rinse and condition. Think I'll have to try it that way. The spray smells lovely but truly don't think it does anything for me
