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.
Onyx + Rose tip
Report shipping damage within 48 hours of delivery — miss that window and you lose eligibility for a free exchange, since Onyx + Rose also caps customers to one refund each.
