How to Make Roasted Onion Peel Hair Oil at Home

This homemade hair oil is simple to prepare and uses ingredients commonly found in many kitchens. The key is to heat everything gently so the beneficial plant compounds infuse into the oils without burning.

Step 1: Prepare the Onion Peels

Collect the papery outer skins from 6–8 large red or yellow onions.

Instructions

Rinse the peels thoroughly to remove dust and dirt.
Pat them completely dry using a clean towel.
Moisture can shorten the shelf life of your oil, so make sure the peels are fully dry before heating.

Step 2: Lightly Roast the Peels

Place a clean, dry frying pan over low heat.

Add the onion peels and stir continuously for 3–5 minutes.

The peels should become slightly crisp and deepen in color.

Do not let them burn, as burnt peels may produce an unpleasant smell and reduce the quality of the infusion.

Step 3: Infuse the Oils

To the same pan, add:

1 cup coconut oil
¼ cup castor oil

Then stir in:

1–2 tablespoons amla powder (or amla oil)
A handful of fresh curry leaves

Optional

You may also add:

1 teaspoon fenugreek seeds

Keep the heat very low and allow the mixture to warm gently for 25–30 minutes.

Avoid frying the ingredients. A few small bubbles around the edges are enough.

Stir occasionally throughout the infusion.

Step 4: Cool the Mixture

Turn off the heat.

Allow the herbs and onion peels to steep in the warm oil for 30–60 minutes as it cools naturally.

This extra resting time helps extract more of the plant compounds into the oil.

Step 5: Strain and Finish

Strain the oil through a fine mesh strainer or cheesecloth into a clean bowl.

Discard the solid ingredients.

If desired, add:

3–4 drops rosemary essential oil

Only add the essential oil after the mixture has cooled to a warm—not hot—temperature.

Stir gently.

Step 6: Store Properly

Pour the finished oil into a clean, dark glass bottle.

Store it:

In a cool, dry place
Away from direct sunlight

Properly stored, the oil can last 8–10 weeks.
