FAQ
How big is the K18 mini hair mask?
The mini is 0.5 oz/15 mL, small enough for carry-on liquid limits. It contains the same formula as the 1.7 oz/50 mL full size.
Is the K18 mini mask a leave-in or a rinse-out treatment?
It is a leave-in. Apply to towel-dried hair, wait 4 minutes and leave it in — no rinsing, and no conditioner beforehand.
Is the K18 mini mask good for travel?
Yes. At 0.5 oz/15 mL it fits carry-on liquid allowances, and one jar is enough to run the recommended 4–6 consecutive-wash repair cycle on shorter hair.
Available in one size: 0.5 oz/15 mL (mini/travel size).
