Herbivore Botanicals tip
There's a 50% rule here: use up more than half the jar and you're only offered store credit, not a refund, even within the 30-day window. Exchanges aren't offered at all, so if a shade or scent is wrong, you're returning for a refund or credit, not swapping.
K18 tip
This generous 90-day window only covers orders placed directly on k18hair.com — if you bought it at your salon, K18 corporate won't take it back, you have to go through the salon itself.
