How to Clean a Scalp Oil Applicator in Two Minutes

An oil applicator only works well when oil can move freely from the reservoir to the tips. Old oil thickens, picks up hair and dust, and slows that flow. The good news: keeping it clean takes about two minutes a week.

After every use: the 30-second rinse

1. Empty any oil you won't use soon back into its bottle, or leave it capped if you'll use it within a few days.
2. Hold the tips under warm (not hot) running water for 20–30 seconds.
3. Shake off the water and stand the comb upright, or lay it flat on a towel, to dry.

Once a week: the soap wash

1. Empty the reservoir.
2. Fill it about halfway with warm water and add one drop of mild dish soap.
3. Cap it and shake gently for 10 seconds, then let the soapy water run out through the tips.
4. Rinse with plain warm water two or three times until no bubbles come out.
5. Let it dry completely before refilling. Water left inside doesn't mix with oil.

When the tips feel slow

• Thick oil in a cold room. Castor and coconut oil stiffen when cold. Warm the comb in your hands, or run the tips under warm water for a few seconds before use.
• Old oil. Oil left in the reservoir for weeks gets sticky. Do the weekly soap wash and start fresh.
• A hair caught in a tip. Rinse from the reservoir side so water pushes it out.

What to avoid

• Boiling water and the dishwasher. High heat can warp clear plastic.
• Strong solvents like alcohol or acetone, which can cloud clear plastic.
• Sharp tools pushed into the tips.

Storing it

Keep it capped with its silicone sleeve, upright or flat, away from direct sun. Capped and clean, the NIB COMB rests on the shelf without leaking, so it is ready for the next wash day.
