Quick Recipe

Prep time: 15 minutes (plus 2-4 days for infusion)

Best for: Hair growth support, stronger hair appearance, scalp nourishment.

Use type: Hair oil

Main ingredients:

  • Red onion
  • Carrier oil (like coconut or olive oil)
  • Optional: Essential oil for scent

Ingredients

  • 1 medium-sized red onion
  • 1 cup carrier oil (such as coconut oil, olive oil, or almond oil)
  • 5-10 drops essential oil (like rosemary, lavender, or peppermint – optional, for scent and added benefits)

How to Make It

  1. Prepare the Onion: Peel the red onion and chop it into small pieces. You can also grate it or blend it into a coarse paste for maximum extraction, but chopping is usually sufficient.
  2. Combine with Oil: Place the chopped onion in a clean, dry glass jar. Pour the carrier oil over the onion pieces, ensuring they are fully submerged.
  3. Infuse the Oil: Seal the jar tightly. You have two main options for infusion:
    • Cold Infusion (recommended): Place the jar in a cool, dark place for 2-4 days. Gently shake the jar once a day to help the onion infuse into the oil.
    • Heat Infusion (quicker): Place the jar (ensure it’s heat-safe) in a saucepan filled with water, creating a double boiler. Heat on low for 15-30 minutes, ensuring the oil doesn’t boil. This can speed up the process but be careful not to overheat the oil.
  4. Strain the Oil: After the infusion period, strain the oil through a fine-mesh sieve or cheesecloth into a clean bottle. Make sure to squeeze out all the oil from the onion pieces. Discard the spent onion pulp.
  5. Add Essential Oils (Optional): If using, add 5-10 drops of your chosen essential oil to the strained onion oil and shake well to combine. This helps to mask the onion smell and can add additional benefits.
  6. Store: Store your homemade onion hair oil in an airtight bottle in a cool, dark place. It should last for several weeks to a month.

How to Use It

  1. Preparation: Before shampooing, part your hair into sections to easily access your scalp.
  2. Application: Take a small amount of the onion hair oil and gently apply it directly to your scalp.
  3. Massage: Using your fingertips, massage the oil into your scalp for 5-10 minutes in circular motions. This helps stimulate blood circulation and ensures the oil penetrates well.
  4. Resting Time: Leave the oil on for at least 30 minutes, or even overnight for a deeper treatment. You can cover your hair with a shower cap to prevent staining and enhance absorption.
  5. Rinse: Wash your hair thoroughly with a mild shampoo, possibly twice, to ensure all the oil and onion scent are removed. Follow with conditioner as usual.

How Often to Use It

For best results, use the onion hair oil 1-2 times a week. Consistent application is key to supporting hair health and appearance.

Why These Ingredients Are Used

Red Onion

Onions are rich in sulfur, a component believed to be beneficial for hair health. Sulfur is a building block of keratin, the protein that makes up hair. Applying onion juice or oil is traditionally thought to nourish hair follicles and support the look of thicker, stronger hair. They also contain antioxidants that may help protect the scalp.

Carrier Oil

A good quality carrier oil like coconut, olive, or almond oil helps dilute the potent onion extracts and delivers essential fatty acids and vitamins to the scalp and hair. These oils moisturize, condition, and can help improve the overall texture and shine of your hair, providing a healthy environment for hair growth.

What Results to Expect

With regular use, this DIY onion hair oil may help support the appearance of visibly stronger, healthier-looking hair. Many users find it helps to improve hair texture, add shine, and nourish the scalp, which can contribute to a more voluminous and longer-looking mane. Individual results can vary, and consistency is important.

Safety Notes

  • Patch test first: Always perform a patch test on a small area of your skin (like behind the ear or inner arm) 24 hours before full application to check for any allergic reactions or irritation.
  • Use gently: Apply the oil with gentle massage; avoid harsh rubbing.
  • Avoid irritated or broken skin: Do not use this oil on a scalp that is irritated, broken, or has open wounds.
  • Stop using if discomfort occurs: If you experience any redness, itching, burning, or discomfort, discontinue use immediately and rinse thoroughly.
  • Strong Odor: Onion oil can have a strong, lingering scent. The addition of essential oils can help, but a faint odor may remain.
  • Eye Contact: Avoid direct contact with eyes. If contact occurs, rinse thoroughly with water.
