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.
Redken tip
Only buy Redken online if you actually got it from Redken.com - products bought at your salon or from an unauthorized reseller aren't eligible for a Redken.com return at all, no matter how recently you bought them.
