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.
WelleCo tip
Because every SKU is ingestible, there's no wiggle room for a simple change-of-mind return — if a canister arrives damaged or wrong, photograph it immediately and contact support directly rather than assuming a standard return process exists.
