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.
Seven Potions tip
Contact them before mailing anything back — the policy explicitly says not to send a return without getting in touch first, and orders over £50 should go back with tracking since they don't guarantee receipt otherwise.
