HygieneLab tip
If your refund hasn't shown up 15 business days after HygieneLab confirms your return was received, that's your cue to follow up directly rather than keep waiting.
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.
