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.
Kurk tip
You don't need to use up the whole product to get a refund — just keep it at least half full, since Kurk analyzes returned batches for their research before refunding.
