How to open Foaming Spray BottleUpdated 3 days ago
TL;DR: Hold the bottle firmly and twist the head anti-clockwise, pressing down on the top as you turn. If it is stuck, five to ten minutes in the freezer or sixty to ninety seconds under warm water usually frees the seal. Then fill to the line and prime the pump.
How do I open Foaming Spray Bottle?
✓ Step by step
Hold the bottle firmly and twist the head anti-clockwise.
If it feels stiff, press down on the top as you twist to release the seal.
Fill to the line from a compatible Koh refill. The mark sits about 1 cm below the shoulder, exactly 300 mL.
Twist the head back on firmly, then prime the pump with two or three pulls until the foam runs steadily.
What if the head is stuck?
⚠ Freeze method
Put the bottle in the freezer for five to ten minutes. The cold contracts the plastic and can loosen the head.
⚠ Warm water method
Run the head under warm, not hot, water for sixty to ninety seconds. The slight expansion frees a stubborn air seal.
✓ Still stuck?
If neither method works after a couple of attempts, contact the Koh UK team rather than forcing the head.
How full should I fill it?
✓ Fill to the line
Fill to the marked line only. The air above the line is what lets the pump aerate the formula into foam.
✓ Leaks or drips
If the bottle leaks, check it is not overfilled and that the pump is tightened properly.
What if it will not foam once it is filled?
✓ Check the refill first
The wrong refill is the most common cause. See Which products can I use with Foaming Spray Bottle? for the full list.
⚠ Clear the nozzle
Twist off the head, soak it in warm water for a few minutes, reattach and pump the trigger twelve or more times.
Hold the bottle upright while spraying. Extreme tilting interrupts the pump.

Just the bottle
Pair Foaming Spray Bottle with any compatible Koh foaming formula for even, clinging coverage.
