Onion hair oil is one of the most powerful natural remedies for promoting faster hair growth and preventing hair fall. Rich in sulfur, antioxidants, and antibacterial properties, onion oil strengthens the roots, improves blood circulation to the scalp, and nourishes hair follicles. When combined with carrier oils like coconut or castor oil, it becomes an effective solution for thicker, shinier, and healthier hair. Making onion hair oil at home is simple, affordable, and completely chemical-free.
Ingredients
-
2 medium-sized onions
-
1/2 cup coconut oil (or olive oil)
-
2 tablespoons castor oil (optional, for extra hair growth)
-
1 tablespoon black seed oil (optional, helps control dandruff)
-
5–7 curry leaves (optional, adds shine and reduces hair greying)
Instructions
-
Prepare the onions: Peel and chop the onions into small pieces. Blend them with a little water to make a smooth paste. Strain the juice using a muslin cloth or fine sieve to separate the liquid from the pulp.
-
Heat the base oil: In a small pan, add the coconut oil (and castor oil if using) and heat it on low flame. Do not let it boil. Add the strained onion juice to the oil and stir well.
-
Infuse the ingredients: Add curry leaves or black seed oil if desired. Let the mixture simmer for about 8–10 minutes on a very low flame until the water from the onion juice evaporates and you see small bubbles. Turn off the flame and allow the oil to cool completely.
-
Strain and store: Once cooled, strain the oil into a clean glass bottle or jar. Store it in a cool, dry place. Shake before each use to mix the ingredients properly.
How to Use
Take 2–3 tablespoons of onion oil and gently massage it into your scalp using circular motions for 10–15 minutes. Leave it on for at least 1 hour or overnight for best results. Wash your hair with a mild shampoo and conditioner. Use 2–3 times a week for noticeable improvement in hair growth and reduction in hair fall.
Benefits
-
Promotes hair growth: The sulfur in onions boosts collagen production, which helps regenerate new hair follicles.
-
Reduces hair fall: Strengthens roots and minimizes hair breakage.
-
Prevents dandruff: Antibacterial and antifungal properties fight scalp infections.
-
Adds shine and softness: Nourishes dry, damaged hair, leaving it smooth and glossy.
-
Delays premature greying: Natural antioxidants slow down the aging of hair follicles.
Tips
Use only low flame when heating the oil to preserve its nutrients. Always strain the oil properly to avoid onion residue in your hair. Add a few drops of essential oils like lavender or rosemary to improve fragrance and boost hair growth further. Store the oil in a dark glass bottle to maintain its potency for a longer time.
Notes
Perform a patch test before using to check for any allergic reactions. Avoid applying directly to cuts or wounds on the scalp. Consistent use for 4–6 weeks will show visible results in hair thickness and strength.
