Onion Hair Oil: 5 Step DYI Homemade Recipe – Long Thick Growth

Onion hair oil is a natural oil made from onions mixed with other oils like coconut or sesame oil. People use it to help their hair grow better, stop hair from falling out too much, and make their scalp healthier. It’s good for hair because onions have stuff in them that helps hair grow and stay strong. It’s been used for a long time in traditional hair care.

How Onion Hair Growth Oil Works?

Onion hair oil works because onions contain sulfur, antioxidants, and antimicrobial properties. Sulfur helps in the production of keratin, a protein essential for hair growth, while improving scalp blood circulation for better nutrient delivery to hair follicles. Antioxidants combat free radicals, preventing hair cell damage, while antimicrobial properties address scalp issues like infections and dandruff. Overall, onion hair oil nourishes the scalp, strengthens hair follicles, promotes healthy hair growth, and improves hair health.

DIY Onion Hair Oil At Home

Use fresh onions for better results. Try different oils to see which one your hair likes best. Keep your oil away from sunlight to keep it fresh. Test a bit of oil on your skin before putting it all over your scalp, just to be safe.

Step by Step Guide

  • Gather Your Ingredients: Begin by gathering the essential components for your Onion Hair Oil concoction. You will need fresh onions, a carrier oil of your choice (such as coconut oil or sesame oil), and optional ingredients like fenugreek seeds or essential oils for added benefits.
  • Chop the Onions: Peel and chop the onions into small pieces. Smaller pieces work better for squeezing out the juice later.
  • Squeeze Out the Juice: Use a blender, grater, or just your hands to get the juice out of the chopped onions. You can use a strainer to get rid of the bits.
  • Mix with Oil: Put the onion juice into a clean jar or bottle, then add your oil. You can use three parts oil to one part onion juice. Mix it up well.
  • Let It Sit: Leave the mixture alone for about a day or more. This lets the good stuff from the onions mix with the oil.
  • Strain and Save: After waiting, strain the oil to get rid of any onion bits. Use a sieve or a cloth to make it smooth. Keep it in a cool, dark place in a clean container.

How To Apply It?

Now that you’ve crafted your own onion hair oil, let’s explore how to apply it effectively for maximum benefits:

  • Application Tips: Begin by parting your hair into sections to ensure even distribution of the oil. Using your fingertips or a clean applicator, gently massage the Onion Hair Oil into your scalp in circular motions. Continue applying the oil along the length of your hair, focusing on the tips to nourish and hydrate dry ends.
  • Recommended Frequency of Use: For optimal results, apply it to your scalp and hair at least twice a week. Consistency is key to reaping the full benefits of this nourishing treatment. Adjust the frequency of application based on your hair’s needs and sensitivity, ensuring not to overuse the oil.
  • Massaging the Scalp: Take a moment to indulge in a gentle scalp massage while applying it. Using the pads of your fingers, apply light pressure and circular motions to stimulate blood circulation and promote nutrient absorption. Pay special attention to areas prone to dryness or irritation, such as the crown and temples.
  • Enhance Absorption with Warmth: To enhance the absorption, consider warming the oil slightly before application. Place the container in a bowl of warm water for a few minutes or use your hands to gently warm the oil before massaging.
  • Allow Time for Absorption: After applying this oil, allow it to penetrate the scalp and hair for at least 30 minutes to an hour before washing it off. For deeper conditioning, you may choose to leave the oil overnight.
  • Rinse Thoroughly: When it’s time to wash off, use a mild shampoo and lukewarm water to thoroughly cleanse your scalp and hair. Repeat the shampooing process if necessary to remove any residue and leave your hair feeling fresh and clean.

Safety Precautions – Dos and Don’ts

  • Conduct a Patch Test: Before applying Onion Hair Oil to your scalp and hair, it’s advisable to conduct a patch test to check for any potential allergic reactions or sensitivities. Apply a small amount of diluted oil to a small area of your skin, such as the inner forearm, and wait for 24 hours to observe any adverse reactions. If you experience redness, itching, or irritation, refrain from using the oil.
  • Avoid Contact with Eyes: Exercise caution to prevent Onion Hair Oil from coming into contact with your eyes. In the event of accidental contact, immediately rinse your eyes with cool water to flush out the oil and seek medical attention if irritation persists.
  • Dilution and Sensitivity: If you have sensitive skin or scalp, consider diluting Onion Hair Oil with a carrier oil before application to minimize the risk of irritation. Carrier oils like coconut oil or almond oil can help to reduce the potency of the onion juice while still delivering nourishment to the hair and scalp.
  • Protect Your Clothing and Linens: Onion hair oil may stain fabrics due to its natural pigmentation. To prevent staining, wear old clothing or use a protective cape while applying the oil. Place a towel over your pillowcase if leaving the oil in overnight to avoid staining your linens.
  • Store Properly: Store it in a cool, dark place away from direct sunlight to preserve its freshness and potency. Ensure that the container is tightly sealed to prevent oxidation and contamination.
  • Keep Away from Children and Pets: Store it out of reach of children and pets to prevent accidental ingestion or contact. Keep the oil in a secure location where it cannot be accessed by curious little hands or paws.

Storage and Shelf Life

  • Store in a Cool, Dark Place: To maintain the integrity, store it in a cool, dark place away from direct sunlight and heat sources. Exposure to light and heat can cause the oil to degrade and lose its potency over time.
  • Use Airtight Containers: Transfer the oil into clean, airtight containers to prevent oxidation and contamination. Choose containers made of dark-colored glass or opaque material to further protect the oil from light exposure.
  • Avoid Moisture and Humidity: Keep it away from moisture and humidity, as excess moisture can promote bacterial growth and spoilage. Ensure that the containers are tightly sealed to prevent moisture from entering.
  • Check for Signs of Spoilage: Regularly inspect the oil for any signs of spoilage, such as a rancid odor, unusual discoloration, or the presence of mold or particles. If you notice any of these signs, discard the oil immediately to prevent adverse effects on your hair and scalp.
  • Shelf Life and Expiry Date: The shelf life of homemade oil can vary depending on factors such as storage conditions, ingredients used, and exposure to contaminants. As a general guideline, Onion Hair Oil prepared with fresh ingredients and stored properly can typically last for up to 2 to 3 months. It’s important to note that natural products do not contain preservatives, so they may have a shorter shelf life compared to commercial products. Discard any leftover oil after the expiry date or if it shows signs of spoilage, and prepare a fresh batch as needed.
  • Refreshing the Oil: If you notice any changes in the aroma or consistency over time, you can refresh the oil by adding a few drops of essential oil or a fresh infusion of onion juice. This can help to rejuvenate the oil and extend its shelf life.
