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.
SkinMedica tip
Refunds go back to your original card and can take up to 14 business days to post once SkinMedica receives the product, so don't panic if it's not instant.
