This article will explore the surprising benefits of onion oil on your hair, how to make it and how to use it! 


Surprising Benefits of Onion Oil for Hair

Onion oil has proved to be one of the best ways to reverse hair loss and promote hair growth. Rich in nutrients like folate, vitamin B6, potassium, vitamin C,  and other essential nutrients that promote the growth of a healthy mane.

The oil works as an antioxidant, anti-fungal, antibacterial and anti-inflammatory properties that enhance scalp and hair health. Here are some fantastic benefits of using onion oil for hair:

  • Reduces Risk of Hair Thinning and Breakage:

Onions are highly rich in sulfur, a nutrient with many benefits to offer. 

In onion oil, this nutrient facilitates the production of collagen, an essential hair protein that helps strengthen and thicken hair strands. This will, in turn, prevent unnecessary hair breakage and thinning, allowing you to grow your dream long and lustrous hair. 

How to use onion oil for hair thinning and loss: 

  • Balances the pH Level of the Scalp and Hair:

  • Our hair is slightly acidic. As we all know, anything above 7 in the pH level is alkaline, while anything below 7 is acidic. The pH of our hair is about 5.3, while that of the scalp is about 5.5.

    The use of harsh hair products can alter the pH level of the scalp and hair, making it more alkaline or more acidic. This can, in turn, cause hair problems. Applying onion oil to your hair can prevent this by balancing the natural pH levels, thereby giving you well-nourished and healthy hair. 

    How to use onion oil for balancing hair pH: 

    • Mix your onion oil with any essential or carrier oil (e.g., coconut, olive, or lavender oil)
    • Apply it to your hair as a mask, and leave it overnight 
    • Wash your hair the next morning with an alcohol-free shampoo

  • Reduces Risk of Premature Greying

  • There are so many reasons you have white hair at an early age. It might be genetics, autoimmune disorders, thyroid problems, excess stress, deficiency in certain nutrients, or smoking. 

    Whatever the cause, you won't be so happy to have white strands while your mates are rocking an all-black silky mane. The solution to this problem is onion oil! It contains vital nutrients and minerals that prevent and reverse premature greying. 

    Onion oil is rich in catalase, an enzyme that, when activated, stimulates the darkening of hair and prevents premature greying. 

    How to use onion oil to prevent premature greying:

    • Warm your pure onion oil and mix it with a teaspoon of lemon juice
    • Massage the mixture into your scalp 
    • Cover with a shower cap for 45 minutes and wash with lukewarm water afterward. 

    • For Treating Dandruff

    Despite being very common, dandruff can be very annoying. Treating them is mostly excruciating and can take you a long time before you treat them. 

    The most daunting part is that dandruff can lead to severe hair problems like hair fall and thinning. But do you know that you can simply get rid of dandruff by using onion oil? 

    Being very rich in antiseptic and antibacterial properties, onion oil can effectively ward off dandruff and help you regain a healthy, nourished scalp. 

    The antibacterial properties also help in strengthening hair strands and making them thicker. 

    How to use onion oil to treat dandruff:

    • Combine onion oil with ginger juice and mix thoroughly
    • Massage your hair to treat dandruff and scalp infections

      • As a Natural Conditioner:

        Conditioner is mostly applied after using shampoo. But do you know you can prevent your shampoo from stripping off your scalp moisture and nourishment? 

        Red onion oil can be massaged deeply into the hair as a conditioner for minutes before using a shampoo. This will reverse dry and frazzled hair while keeping your scalp moisturized. 

        How to use onion oil as a natural conditioner: 

        • Warm your onion oil and allow it to cool
        • Massage it into your hair strands and scalp and cover with a towel
        • Wash your hair with a mild shampoo and apply a conditioner.

          How to Extract Onion Oil at Home

          There are many brands producing onion oil and marketing it online and in shops. However, if you're not willing to buy online or from grocery stores, then you'll have to make your onion oil at home. 

          Here's a simple DIY onion oil:

          • Get 3 or 4 fresh bulb onions (it's advisable to make a small amount to see how the oil turns and how it affects your hair)
          • Chop the onions and blend them into a smooth paste
          • Keep the paste aside and let it settle
          • Add a carrier oil (e.g, coconut oil) into a pan and warm it on a low flame until the oil starts to boil
          • Add your onion paste into the oil and mix thoroughly for two to three minutes
          • Off your heat and allow the concoction to cool 
          • Strain the oil and store it in an airtight container 
          • The oil can last for up to 2 years, but it's only effective on your hair for six months.

              How the Ingredients of Onion Oil Promote Hair Growth

              You might be wondering what's the use of the ingredients that are used in making onion oil. Well, all these ingredients help either in reversing hair loss, nourishing the scalp, or promoting hair growth.  Below are their benefits:

              • Coconut oil: is regarded as one of the best oils to keep your hair well-nourished with proteins. The oil contains a high amount of lauric acid, which makes it easily absorbable into the hair shafts. It also replenishes hair strands, nourishes the scalp, and adds luster to your hair. 
              • Fenugreek Seed: this plant is rich in compounds that interact with DHT and slows down its ability to attach to your scalp. Studies have also related the seeds to increase hair thickness and growth. 
              • Garlic: it is highly rich in antibacterial properties that combat bacteria and other microorganisms that damage the scalp and cause hair breakage and thinning. The plant is also rich in vitamin c, which is essential for the growth of healthy hair. Garlic also stimulates the production of collagen, an essential hair growth nutrient.
              • Curry leaves: Also known as Kadi Patta, they're highly rich in anti-inflammatory and antioxidant properties. The antioxidants, together with Vitamin B, can stimulate the production of melanin in the hair, thereby reducing the risk of premature aging.  The nutrients in curry leaves also help in removing dead hair follicles and preventing hair thinning. 

              These ingredients, together with onions, provide your hair with the nutrients and minerals that nourish and improve hair growth

                      • Avoid using onion oil more than twice a week as excess usage can cause inflammation.
                      • Always do a patch test before applying the oil to your scalp, as it can sometimes cause an allergy. 
                      • Avoid leaving the oil for a long time on your hair, especially if you've sensitive skin. Wash it off after 2 to 3 hours of application.
                      • Onions are known to cause watery eyeless and also the oil. Make sure you're putting a small amount of the oil, and cease using it if it's causing you to tear up frequently 


                        Onion oil is highly rich in antioxidants that help reverse and prevent premature aging. Its antimicrobial properties help ward off itchiness, dandruff, and other scalp infection.

                        However, you should avoid using too much onion oil as it can lead to scalp irritation and dryness.
