Quick Recipe

Prep time: 15 minutes

Best for: Supporting hair growth, scalp health, and hair volume

Use type: Hair oil

Main ingredients:

  • Red onion
  • Carrier oil (coconut, olive, or almond)

Ingredients

  • 1-2 medium-sized red onions
  • 1 cup (approx. 240ml) of a preferred carrier oil (such as organic coconut oil, extra virgin olive oil, or sweet almond oil)

How to Make It

  1. Prepare the Onion: Peel and finely chop or grate the red onions. The finer the pieces, the more easily the onion juice can be extracted.
  2. Extract Onion Juice (Optional but Recommended): For a quicker infusion, you can blend the chopped onion in a food processor and then strain it through a cheesecloth or fine-mesh sieve to extract the onion juice. Alternatively, you can proceed directly with the chopped onion.
  3. Heat the Oil: In a clean, dry saucepan, combine your chosen carrier oil with the chopped red onion (or onion juice if extracted). Heat the mixture over very low heat. Do not let it boil or smoke. The goal is a gentle infusion, not cooking.
  4. Infuse Gently: Continue heating on low for about 10-15 minutes, stirring occasionally. You’ll notice the oil changing color slightly and absorbing the essence of the onion. If using chopped onion, ensure it doesn’t burn.
  5. Cool and Strain: Remove the pan from heat and let the mixture cool completely. Once cool, strain the oil through a fine-mesh sieve or cheesecloth into a clean, airtight glass bottle or jar. Press down on the onion solids to extract as much oil as possible.
  6. Store: Seal the bottle tightly. Store the red onion hair oil in a cool, dark place. It can last for several weeks.

How to Use It

  1. Patch Test: Before full application, apply a small amount of the oil to a discreet area of your skin (like behind your ear or inner arm) and wait 24 hours to check for any adverse reactions.
  2. Section Hair: Part your hair into sections to easily access your scalp.
  3. Apply to Scalp: Take a small amount of the red onion hair oil and gently massage it directly onto your scalp using your fingertips. Ensure even coverage across the entire scalp.
  4. Distribute to Hair (Optional): If desired, you can also gently work some of the oil through the lengths of your hair.
  5. Leave On: Leave the oil on for at least 30 minutes, or for a deeper treatment, you can leave it on overnight (covering your pillow with a towel to protect it).
  6. Rinse and Shampoo: Wash your hair thoroughly with a mild shampoo and conditioner. You may need to shampoo twice to completely remove the oil and any lingering onion scent.

How Often to Use It

For best results, aim to use this red onion hair oil 1-2 times a week. Consistency is key with natural remedies.

Why These Ingredients Are Used

Red Onion

Red onions are a traditional home remedy for hair care, largely due to their rich sulfur content. Sulfur is a component of keratin, a protein vital for strong hair. It’s believed that applying onion juice or oil to the scalp may help nourish hair follicles, support circulation, and potentially contribute to a healthy environment for hair growth. Onions also contain antioxidants that help protect the scalp.

Carrier Oil

Carrier oils like coconut, olive, or almond oil serve as a base to dilute the potent onion extract and provide additional benefits. These oils are known for their moisturizing, nourishing, and protective properties. They can help condition the hair, reduce breakage, and keep the scalp hydrated, creating an optimal environment for hair health.

What Results to Expect

While results can vary for everyone, regular use of red onion hair oil may help support the appearance of thicker, healthier, and more voluminous hair. Many users report that their hair feels softer and looks shinier, and the scalp feels more nourished. Consistent application over several weeks or months can help promote a healthier scalp and create a better foundation for natural hair growth.

Safety Notes

  • Patch Test First: Always perform a patch test 24 hours before applying the oil to your entire scalp to check for any allergic reactions or irritation.
  • Avoid Irritated Skin: Do not apply the oil to an irritated, broken, or sensitive scalp.
  • Strong Odor: Be aware that red onion has a distinctive smell that might linger even after washing. You can try adding a few drops of essential oils like rosemary or lavender to the carrier oil during infusion to help mask the scent, but always patch test essential oils too.
  • Discontinue Use: If you experience any redness, itching, burning, or discomfort, stop using the oil immediately and rinse thoroughly.
  • Consult a Professional: If you have underlying scalp conditions or concerns about hair loss, consult a dermatologist or healthcare professional.

FAQ

Can I use this oil every day?

While generally safe, it’s recommended to use this oil 1-2 times a week. Daily use might be too intense for some scalps, and could lead to excessive oiliness or irritation if not properly rinsed.

How long does the red onion hair oil last?

When stored in a cool, dark place in an airtight container, homemade red onion hair oil can typically last for 2-4 weeks. If you notice any changes in smell, color, or texture, it’s best to discard it.

Does red onion hair oil really make hair grow faster?

Red onion hair oil is believed to support hair growth by providing sulfur and nutrients to the scalp, which can create a healthier environment for follicles. While it may help improve the appearance of hair density and stimulate existing growth, dramatic overnight results are not realistic. Consistency and patience are key.
