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.
LYMA tip
LYMA sells high-cost devices like the LYMA Laser alongside supplements, so before buying, email their Concierge team directly to confirm the return window on the specific product - the FAQ splits policy details by product line rather than one blanket rule.
