Looking for a natural way to support your hair’s vitality? This DIY onion hair oil recipe is a popular home remedy often used to encourage the appearance of fuller, healthier hair.

Quick Recipe
Prep time: 15 minutes (plus infusion time)
Best for: Supporting hair growth, stronger hair, healthy scalp
Use type: Hair oil
Main ingredients:
- Fresh red onion
- Carrier oil (e.g., coconut oil, olive oil, or almond oil)
Ingredients
- 1 large red onion, peeled and finely chopped or grated
- 1 cup carrier oil (such as virgin coconut oil, extra virgin olive oil, or sweet almond oil)
- (Optional) 5-10 drops of essential oil (e.g., rosemary, peppermint, or lavender for scent and added benefits)
How to Make It
- Prepare the Onion: Peel and finely chop or grate the red onion. The smaller the pieces, the more surface area for infusion.
- Combine Ingredients: In a clean, dry glass jar, combine the chopped onion with the carrier oil. Ensure the onion is fully submerged.
- Heat Gently (Optional, but recommended): You can gently heat the mixture using a double boiler method for about 10-15 minutes on low heat. This helps release the onion’s beneficial compounds into the oil. Do not boil the oil. Alternatively, you can let it infuse at room temperature.
- Infuse: If not heating, seal the jar and place it in a cool, dark place for 3-5 days. If you heated it, let it cool completely before sealing and storing. Shake the jar gently once a day.
- Strain the Oil: After the infusion period, strain the oil through a fine-mesh sieve or cheesecloth to remove all onion pieces. Squeeze out as much oil as possible.
- Add Essential Oil (Optional): If using, stir in your chosen essential oil(s) into the strained onion oil.
- Store: Transfer the finished onion hair oil into a clean, airtight glass bottle. Store in a cool, dark place.

How to Use It
- Prepare Your Hair: Ensure your hair is dry or slightly damp. You can lightly detangle it before application.
- Apply to Scalp: Take a small amount of the onion hair oil in your fingertips. Section your hair and apply the oil directly to your scalp, focusing on areas where you desire more growth or thickness.
- Massage Gently: Using your fingertips, gently massage the oil into your scalp for 5-10 minutes in circular motions. This helps improve blood circulation and ensures the oil is absorbed.
- Distribute Through Hair (Optional): If desired, you can also apply a small amount of oil to the lengths of your hair for added conditioning and shine.
- Leave On: Leave the oil on for at least 30 minutes. For deeper conditioning, you can leave it on for 1-2 hours, or even overnight if comfortable. Cover your hair with a shower cap to avoid staining linens.
- Rinse and Wash: Wash your hair thoroughly with a mild shampoo. You may need to shampoo twice to fully remove the oil and the onion scent. Condition as usual.
How Often to Use It
For best results, use this onion hair oil 1-2 times a week. Consistency is key with natural remedies.
Why These Ingredients Are Used
Red Onion
Onions are rich in sulfur, a component believed to help with hair strength and growth. They also contain antioxidants that may help protect hair from environmental damage and support a healthy scalp environment.
Carrier Oil
Oils like coconut, olive, or almond oil are excellent bases for hair remedies. They are rich in fatty acids and vitamins that nourish the scalp, condition hair strands, and help deliver the beneficial compounds of the onion. Coconut oil, in particular, is known for its ability to penetrate hair shafts and reduce protein loss.
Essential Oils (Optional)
Essential oils like rosemary are often used to support hair growth, while peppermint can stimulate the scalp. Lavender provides a pleasant scent and may help soothe the scalp.
What Results to Expect
With consistent use, this onion hair oil may help support a healthier scalp, which is foundational for hair growth. Your hair may feel softer, look shinier, and appear thicker over time. It can also help reduce the appearance of hair fall, contributing to a fuller-looking mane. Remember that natural results can vary and take time to become noticeable.

Safety Notes
- Patch Test First: Always perform a patch test on a small area of your skin (e.g., behind the ear or on your inner arm) 24 hours before full application to check for any allergic reactions or irritation.
- Avoid Eye Contact: Onion can be irritating to the eyes. Be careful during application and rinse immediately with plenty of water if contact occurs.
- Strong Scent: Onion oil has a distinct smell. While it usually washes out, some residual scent might remain. Adding essential oils can help mask it.
- Use Gently: Apply and massage the oil gently. Do not rub aggressively, as this can cause irritation or damage to hair strands.
- Stop if Discomfort Occurs: If you experience any redness, itching, burning, or discomfort, discontinue use immediately and rinse thoroughly.
- For External Use Only: This remedy is for topical application to hair and scalp only. Do not ingest.
FAQ
How long does homemade onion hair oil last?
When stored in a cool, dark place in an airtight container, homemade onion hair oil typically lasts for about 2-4 weeks. If you notice any change in color, smell, or texture, it’s best to discard it.
Can I use white or yellow onions instead of red?
While red onions are often preferred for their higher sulfur content, white or yellow onions can also be used. The principle remains the same for infusing their beneficial compounds into the oil.
Does onion oil really help with hair loss?
Onion oil is traditionally used to support hair health and reduce hair fall. The sulfur in onions is believed to improve blood circulation to the scalp and provide nourishment to hair follicles, which can help strengthen hair and reduce breakage, contributing to less hair loss and supporting new growth.
