Quick Recipe
Prep time:
20 minutes (plus 1-2 weeks for infusion)
Best for:
Dull, lifeless hair, dry scalp, and promoting a healthier hair appearance.
Use type:
Hair oil
Main ingredients:
- Kalonji seeds (black seeds)
- Red onion
- Fresh rosemary
- Carrier oil (e.g., coconut or olive oil)
Ingredients
- 1/4 cup kalonji seeds (black seeds)
- 1 small red onion, peeled and roughly chopped
- 2-3 sprigs of fresh rosemary
- 1 cup carrier oil (such as organic virgin coconut oil, olive oil, or almond oil)
- Optional: 5-10 drops of rosemary essential oil (if not using fresh rosemary or for extra potency)
How to Make It
- Prepare the ingredients: Ensure the onion is dry after chopping to avoid water contamination in the oil. Lightly crush the kalonji seeds using a mortar and pestle or by placing them in a bag and gently tapping with a rolling pin. This helps release their beneficial compounds.
- Combine and heat (optional, for quicker infusion): In a clean, dry saucepan, combine the carrier oil, crushed kalonji seeds, chopped onion, and fresh rosemary sprigs. Heat on very low heat for about 15-20 minutes, ensuring the oil does not boil. This gentle heat helps to infuse the properties into the oil more quickly. Alternatively, skip heating and proceed directly to step 3 for a slower, cold infusion.
- Infuse the oil: Carefully transfer the oil mixture (ingredients included) into a clean, dry glass jar with a tight-fitting lid. If you didn’t heat the oil, simply add all ingredients to the jar with the carrier oil.
- Store and steep: Seal the jar and store it in a cool, dark place for 1 to 2 weeks. Gently shake the jar every day or two to help the infusion process. If using the optional rosemary essential oil, add it after the infusion process, once the oil has cooled (if heated) and before straining.
- Strain and store: After the infusion period, strain the oil through a fine-mesh sieve or cheesecloth into another clean, dry glass bottle or jar. Discard the solid ingredients. Your homemade hair oil is now ready.

How to Use It
- Apply: Take a small amount of the hair oil and gently massage it into your scalp using your fingertips. Ensure even distribution, working your way down to the hair strands if desired.
- Massage: Spend 5-10 minutes massaging your scalp in circular motions. This helps to stimulate blood circulation and ensures better absorption of the oil.
- Leave on: You can leave the oil on for at least 30 minutes, or for a deeper treatment, leave it overnight. Covering your hair with a shower cap can enhance absorption and protect your pillow.
- Rinse: Wash your hair thoroughly with a mild shampoo, followed by a conditioner. You may need to shampoo twice to ensure all oil is removed.
How Often to Use It
For best results, use this DIY hair oil 1-2 times a week. Consistent use can help in maintaining scalp health and promoting the appearance of shinier, healthier hair.
