Quick Recipe
Prep time: 15 minutes
Best for: Supporting hair volume, scalp health, and general hair appearance
Use type: Oil
Main ingredients:
- Onion
- Coconut oil
- Fenugreek seeds
Ingredients
- 1 medium-sized red onion, peeled and finely chopped or grated
- 1/2 cup pure coconut oil (or sesame oil)
- 1 tablespoon fenugreek seeds
- 5-7 fresh curry leaves (optional, but beneficial)
- 1 teaspoon black cumin seeds (kalonji) (optional)
How to Make It
- Prepare the Onion: Peel and finely chop or grate the red onion. You can also blend it into a fine paste.
- Heat the Oil: In a heavy-bottomed pan, add the coconut oil. Heat it over low-medium flame until it’s warm, but not smoking.
- Infuse Ingredients: Add the chopped onion, fenugreek seeds, curry leaves, and black cumin seeds (if using) to the warm oil.
- Simmer Gently: Continue to heat the mixture on a very low flame. Stir occasionally. Allow it to simmer until the onion pieces turn light golden brown and crispy, and the aroma of the herbs and onion infuses into the oil. This usually takes about 10-15 minutes. Be careful not to burn the ingredients, as this can destroy their beneficial properties.
- Cool and Strain: Once the onion and herbs are cooked, turn off the heat and let the oil cool down completely.
- Store: Once cooled, strain the oil using a fine-mesh sieve or a cheesecloth into a clean, airtight glass bottle. Discard the solid residue.

How to Use It
- Section Hair: Part your hair into sections to easily access your scalp.
- Apply Oil: Take a small amount of the onion hair oil on your fingertips.
- Massage Scalp: Gently massage the oil into your scalp using circular motions for 5-10 minutes. Ensure even distribution.
- Apply to Lengths: You can also apply a small amount of oil to the lengths of your hair if desired.
- Leave On: Leave the oil on for at least 30 minutes to an hour. For deeper conditioning, you can leave it overnight.
- Rinse: Wash your hair thoroughly with a mild shampoo and conditioner. You may need to shampoo twice to remove the oil completely and neutralize any residual onion smell.
How Often to Use It
For best results, use this onion hair oil 1-2 times a week. Consistent application can help support your hair care routine over time.
