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.
Tata Harper tip
You don't need to use a product sparingly to protect your return rights — Tata Harper accepts returns as long as the bottle is still at least half full, which is more forgiving than the all-or-nothing policies most skincare brands run.
