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.
Obagi tip
The prepaid return label expires 7 days after it's issued, so don't request it until you're actually ready to ship the box back.
