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.
Sensica tip
The 120-day window sounds generous, but Sensilift and Sensifirm devices carry a $35/month usage fee during your trial, so returning one after 3-4 months can eat a big chunk of your refund.
