Wen causing irritation, should I stop?

I've been using Wen SAM cc for a few weeks and it has made my hair AMAZING. Except tonight when I used it my scalp started to burn. This is the first time it's happened. I live in Canada and Wen doesn't offer any menthol-free options to Canadians. Should I stop using it, or try a few more times?

I think you should stop using it. No matter how nice your hair looked in the past few weeks, burning is not a good sign. Burning sometimes precedes hair loss as well. Your body is quite clearly rejecting it and sending out warning signs. 
Did you do anything different to your hair or scalp before or after this application that could have caused the problem? Seems weird you were able to use it w/out any problems for several weeks and then bam!
