Pompe à litre Davines

Yes, the pump ships locked — this is intentional for shipping. The step most people miss: unlock the pump before inserting it into the bottle. Hold the base firmly, then twist the nozzle counterclockwise. It will pop up into the dispensing position. Do this while the pump is still outside the bottle — if you insert it locked and try to twist inside the bottle, the locking ring can fall in and be very hard to retrieve.

Yes, this pump fits OI Shampoo 1000ml, OI Conditioner 1000ml, and the full Essential Haircare 1L range including DEDE, MOMO, NOUNOU, MELU, MINU, LOVE CURL, LOVE SMOOTH, and other Essential Haircare litre sizes. It does not fit retail sizes (250ml, 280ml), 500ml bottles, or Naturaltech 1L bottles — Naturaltech uses a separate pump.

No — it needs priming. The pump tube is empty on first install and needs 3–5 pumps to draw product up before it dispenses. This is normal on first use or after the pump has been stored dry and reinserted into a new bottle. If it still doesn't dispense after several pumps, confirm the nozzle is fully unlocked (twisted counterclockwise into the up position) and that the pump is seated firmly in the bottle neck.

Yes — the pump is designed to be reused across multiple bottles. When the bottle is empty, lock the nozzle by twisting clockwise, remove the pump, rinse thoroughly under warm water, and allow to dry completely before inserting into the next bottle. Davines specifically recommends reusing rather than discarding.

You need one pump per bottle if you want both open at the same time. If you only buy one pump, you will need to move it between bottles each wash, which works but is less convenient. Most clients who buy both OI or Essential Haircare litre bottles in the same line add two pumps at checkout — one per bottle.
