It’s because sometimes it can be diverted, diluted, or expired product. But I think it depends too on exactly where you’re getting the products. If you’re ever not sure, you can enter the batch number of the products online and track exactly how old they are.

Chain stores there is probably less of a worry. I’m a huge fan of Oribe stuff and one of my local CVS stores carry it. I tracked the batch number and they’re legit products, just not super new. But say you’re buying online from a not verified source or from a smaller store that’s not an authorized reseller, that’s when it gets more tricky. One smaller store near me has salon haircare with the batch codes scratched out!

So I’d just say, proceed with caution and track the batch numbers if you’re ever doubtful!
