Quick Recipe

Prep time: 15 minutes

Best for: Hair growth, thickness, and strength

Use type: Hair oil

Main ingredients:

  • Onion
  • Carrier Oil (e.g., coconut oil, olive oil, almond oil)

Ingredients

  • 1 large onion (red or white)
  • 1 cup carrier oil (such as organic coconut oil, extra virgin olive oil, or sweet almond oil)
  • Optional: 2-3 drops of essential oil for fragrance (e.g., lavender, rosemary, tea tree)

How to Make It

  1. Prepare the Onion: Peel and finely chop the onion. You can also grate it or blend it into a fine paste (without adding water). The finer the pieces, the more easily the beneficial compounds can infuse into the oil.
  2. Heat the Oil: In a heavy-bottomed pan or pot, pour your chosen carrier oil. Add the chopped or pureed onion to the oil.
  3. Infuse Gently: Heat the mixture over very low heat. Do not let the oil smoke or the onion burn. Simmer gently for about 10-15 minutes. The goal is to allow the onion’s properties to infuse into the oil without cooking it too intensely. You’ll notice the onion pieces starting to turn light golden brown.
  4. Cool and Strain: Remove the pan from heat and let the oil cool completely. Once cool, strain the oil using a fine-mesh sieve or a cheesecloth to separate the onion pieces from the infused oil. Squeeze the onion pulp well to extract all the oil.
  5. Store the Oil: Transfer the onion-infused oil into a clean, airtight glass bottle or jar. Store it in a cool, dark place.

How to Use It

  1. Section Your Hair: Divide your hair into manageable sections.
  2. Apply to Scalp: Take a small amount of the DIY onion oil and gently massage it directly onto your scalp using your fingertips. Ensure even coverage across your entire scalp.
  3. Spread to Ends (Optional): If desired, you can lightly apply a small amount of oil to the lengths and ends of your hair for added conditioning.
  4. Massage: Massage your scalp for 5-10 minutes to help stimulate blood circulation.
  5. Leave On: Leave the oil on for at least 30 minutes to 2 hours. For deeper conditioning, you can leave it overnight, covering your hair with a shower cap or old towel to protect your pillow.
  6. Rinse and Wash: Wash your hair thoroughly with a mild shampoo. You may need to shampoo twice to completely remove the oil and any lingering onion scent.

How Often to Use It

For best results, use this DIY onion oil 1-2 times a week. Consistent use over several weeks is key to observing potential benefits for your hair’s appearance.

Why These Ingredients Are Used

Onion

Onions are rich in sulfur, a mineral that is a key component of keratin, the protein that makes up hair. The sulfur in onions is believed to help support the strength of hair follicles and may contribute to healthier-looking hair. They also contain antioxidants that help protect hair from environmental damage, which can indirectly support overall hair health.

Carrier Oil

Carrier oils like coconut, olive, and almond oil are excellent for nourishing the scalp and hair. They provide essential fatty acids, vitamins, and minerals that moisturize, condition, and protect the hair strands. They also help deliver the benefits of the onion deep into the scalp.

What Results to Expect

Consistent use of DIY onion oil may help improve the appearance of hair thickness and promote a healthier-looking scalp. Your hair may feel softer, stronger, and appear more lustrous over time. While results can vary, many users find that incorporating onion oil into their routine supports their hair’s natural vitality.

Safety Notes

  • Patch Test First: Always perform a patch test on a small area of your skin (like behind your ear or inner arm) 24 hours before applying the oil to your entire scalp to check for any allergic reactions or irritation.
  • Onion Scent: Onion oil can have a strong, distinct smell. While thorough rinsing and shampooing can minimize it, some scent may linger. Adding a few drops of essential oil can help.
  • Avoid Eye Contact: Be careful to avoid getting the oil in your eyes, as it can cause irritation.
  • Stop if Discomfort Occurs: If you experience any burning, itching, redness, or discomfort, discontinue use immediately and rinse your hair and scalp thoroughly.
  • Not for Open Wounds: Do not apply to irritated, broken, or sensitive skin on the scalp.
  • Consult a Professional: If you have any scalp conditions or severe hair loss, consult a dermatologist or healthcare professional before trying new home remedies.
