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.
Sonage Skincare tip
If a product arrives damaged or wrong, report it within 3 business days — Sonage replaces those at no cost, but that's a much tighter window than the general 14-day return period.
