Stability testing Hair Butter and Hair Conditioner
I was wondering if I need to do the temperature variation as part of my stability test for a hair butter or should I only do the stability packaging test. The hair butter is completely water free.

You don’t “have to” do any sort of stability or packaging test if you don’t want to. That testing is done so that you can figure out whether or not your product will be stable in the long term. If you don’t care that your product might fall apart, degrade, or grow mold after a period of time sitting on the shelf, by all means, don’t test.

Yes, you should.
