Onion Juice and Its Historical Uses

Onion has been used for over 5000 years, both as a diet staple and for its use in the treatment of a wide range of maladies.

While the exact location of the onion’s original cultivation is still unclear, these healthy and flavorful vegetables have been cultivated in one form or another around the globe.And, as if the many benefits offered by onions wasn’t already enough, scientists have now learned of its effectiveness at treating hair loss and regrowing hair in those with thinning and baldness.

Can Onion Juice Help with Hair Growth?

While onion juice may seem like an odd treatment for hair loss, there are a number of reasons why onion juice is effective at treating hair loss and helping to regrow hair.

Onion Juice Contains Sulfur

Methylsulfonylmethane is an organic compound found within the body. This compound is broken down by the body for use of its sulfur, which contributes to bone, hair, and nail growth.

While a sulfur deficiency may not be the main reason for your hair loss, supplementation with sulfur can certainly contribute to hair growth.

This is great news for onion lovers, as onions are sulfur-rich vegetables. If you’re not an onion lover, however, the application of onion juice to the scalp can still provide benefits and contribute to hair growth and strengthening.

Onion Juice is Anti-microbial

Onion has been proven to contain anti-microbial properties, and this can be helpful in battling the natural buildup of oils, chemicals, and DHT on your scalp. Further, onion juice can fight infections and leave you with healthy and strong hair follicles from which healthy hair can grow.

Onion Juice is Full of Antioxidants

Onions are a particularly large source of flavonoids and are perhaps one of the main contributors of flavonoid intake in humans But, what are flavonoids, and how can they help to prevent further hair loss and even contribute to hair growth?

Flavonoids are versatile compounds, and as such, they provide a number of functions in the plants they’re found within. One such plant is the onion, in which they serve as an antioxidant.

For men suffering from male-pattern baldness, antioxidants can provide a number of benefits. One such benefit is the neutralization of free radicals, the molecules which are responsible for aging.

In men with male-pattern baldness, free radicals are, in large part, responsible for hair thinning and loss. This is because these molecules destroy hair follicles and make it difficult for hair regrowth to occur.

Onion Juice is Anti-inflammatory

As you can imagine, the damage done by free radicals to the hair follicles can be particularly irritating and inflammatory.

That’s one more reason that onion juice is an effective treatment for hair loss; its anti-inflammatory properties make it useful at decreasing hair follicle inflammation and irritation and creating a healthy environment for hair growth to occur.

What Science Has to Say About Onion Juice and Hair Loss

There’s no doubt that onion juice has a number of properties which make it effective at treating hair loss no matter the cause. But have there been any scientific studies done to prove its effectiveness?

While current research is lacking, one study which was performed in 2002 and published in the Journal of Dermatology has shown the effectiveness of onion juice for the treatment of hair loss.

This particular study focused on patients with alopecia areata (a form of hair loss that’s different from male-pattern baldness and which will be discussed later).

The study consisted of 38 patients, and these patients were split into two groups.

Group one, which consisted of 23 participants (16 males and 7 females), were instructed to apply onion juice to their scalp twice per day for two months.

Group two, which consisted of 15 participants (8 males and 7 females), were instructed to apply tap water to their scalp twice per day for two months.

At the end of the 8-week study, only two patients from the tap water group showed signs of observable hair re-growth. The group which applied onion juice to their scalps, however, had a stunning 20 participants with observable hair re-growth by week 6. That’s 86.9% of the group!

Can Onion Juice Treat Other Forms of Hair Loss Besides Alopecia Areata?

The above study was performed on individuals with alopecia areata.

Alopecia areata is a form of hair loss which is caused by the immune system attacking healthy hair follicles. These attacks will eventually alter the hair growth cycle, miniaturize the hair follicle, and lead to halted hair growth.

But what about those who suffer from androgenetic alopecia, also known as male-pattern baldness?

While the reason for the miniaturization of the hair follicle is different than in those with alopecia areata (DHT vs immune system attack), the fact still remains that miniaturized hair follicles will halt hair growth completely.

While onion juice may not reduce the production of DHT found in the body, it can help to reduce the amount of DHT found on the scalp, reduce inflammation of the hair follicles, and reverse the effects of miniaturization of the hair follicles.

This means that onion juice can be effective at treating hair loss in those with male-pattern baldness and other forms of hair loss.

Are There Side Effects Associated with Application of Onion Juice?

As with any supplement, it’s important to speak with your doctor if you have any pre-existing medical conditions or concerns.

Onion juice, when applied directly to the skin, may cause temporary irritation and burning. Apply onion juice to a small patch of skin on your wrist prior to use on your scalp. This will give you an idea of how your body reacts to its use and whether you’ll have any issues with use.

If you’re pregnant or nursing, consult with your obstetrician prior to use of the supplement.

And, of course, if you’re allergic to onion, avoid use, even if it’s non-oral.

How Can You Add Onion Juice to Your Hair Care Routine?

Apply It Directly

If you want to reap the most benefits associated with onion juice, then direct application the scalp is the best method to use.

There are two main ways of extracting onion juice from onions. One involves the use of a juicer, and the other uses a garlic press.

When using a juicer, cut the onion into quarter-sized pieces and peel. Feed the onion pieces, one by one, into the juicer.

With a garlic press, cut the onion into eighths (or smaller), and peel. Place on piece of onion into the garlic press, and squeeze over a cup or bowl until all of the juice has been extracted.

Repeat until all onion pieces have been thoroughly juiced. Learn more about how to use vegetables juices for hair loss here.

Now that the juice has been extracted, pour into your palm and massage between hands. Rub the juice into your scalp in a slow, circular motion.

Be aware that juice may flow down your scalp, so avoid direct application to the front of the hairline to avoid onion juice getting into your eyes. Instead, apply to the top of the scalp and spread the juice outward.

The onion juice should absorb, though there will be left over residue. Rinse after at least 15 minutes, or leave the onion juice on your scalp overnight and then rinse and shampoo in the morning.

Add It To Your Shampoo

Ketoconazole is a key ingredient of some popular hair loss shampoos

While the direct application of onion juice to the scalp is the simplest form of treatment for hair loss, it’s understandable that some individuals may not be enthused with the idea.

If you’re one such individual, then adding onion juice to your shampoo may be an easy way to incorporate onion juice into your hair care routine.

While onion juice can be added to store-bought shampoo, some individuals may be more interested in a natural and chemical-free shampoo alternative.

If you’d like to give chemical-free shampoo a try, consider testing out one of the base shampoos mentioned below and adding onion juice for an extra boost.

Shampoo for Hair Growth


Bring water to a boil. Add 2 – 3 bunches of nettle and allow to steep. Strain.

Add the rest of the ingredients to the nettle tea, and mix. Also add one teaspoon of onion juice to the base.

Lather onto wet hair, and allow to sit for at least 2 minutes and up to 5. Rinse thoroughly.

If the onion scent is too strong, shampoo your hair a second time with the above shampoo base, this time without the onion juice included. Stinging nettle helps to clean the scalp pores, block DHT and reduce inflammation.

Make an Onion Juice Hair Mask

Applying a hairmask to protect the hair follicles and scalp

Hair masks are a simple way to add onion juice to your regular hair care routine, and it can be applied in as little as 5 minutes.

Onion Juice and Honey Hair Mask

  • 2 tablespoons onion juice
  • 1 tablespoon honey

Cut a medium – large onion into quarter-sized pieces. Peel one of the quarter-sized pieces.

Next, with the help of a garlic press or juicer, juice the onion.

You may need to use more than one-quarter sized piece of onion.

Once you’ve collected two tablespoons of onion juice, combine with one tablespoon of honey and mix.

Apply the onion juice and honey mixture all over your scalp in a thin layer. Leave on for at least 15 minutes, though you can also cover with a towel or shower cap and leave it on overnight.

Rinse, and then shampoo your scalp as usual.

This method can be done at least once per month, though it’s best to do it no more than once per week.


Although there is no absolutely firm evidence that onion juice can be used to treat male pattern baldness, there is good reason to believe that is would be a beneficial addition to your hair care routine doe to its ability to reduce inflammation and reduce DHT levels in the scalp.

However, for now I believe there are more powerful ways to regrow your hair naturally without using onion juice and this is something I show you how to do in step by step detail inside Hair Equilibrium.

    Have any questions for me about using onion juice for your hair type? Just post it here in the comments and I’ll try to answer you within a day 🙂

    • Abhinav says:

      I have been experiencing drastic hairfall from last 1 year. 4 months back i have started applying monoxidil.Everytime i apply monoxidil, my hair gets rough and fall out.I am currently washing hair on regular basis with organic shampoo, using monoxidil, taking hair vitamins but i dont feel any progress here.My hair have become very thin. Do you think adding onion juice to this regime will help?

      • Will Hartfield says:

        Hi Abhinav, honestly I don’t think onion juice will help very much. Topical applications have limited effectiveness. You need to first sort out your body so you’re not fighting a losing battle. Then maybe use the onion juice to speed up recovery. Also, I would not recommend shampooing too much, even with an organic shampoo. Try using just apple cider vinegar (4 teaspoons per wash) once per week, with no shampooing. Natural oils that are removed during shampooing help to protect the scalp and hair follicle.

        • asfandyar khan says:

          Sir first of all thanks to all from the core of my heart that you spare your precious time for us to talk on the issues regarding our health,
          Sir I’ve seen a lot time that onion juice is good but I have been using it for the last couple of ears , I am 25 + , do you think it’ll help me and recover my bald patches

          • Will Hartfield says:

            Topical applications only have limited effectiveness. I wouldn’t rely on this to regrow hair, there are other changes you need to make from the inside-out first.

  • kanishka says:

    I have had hairfall n hairloss about 3-4 yrz ago..can i regrow my hairs back with onion juice..if i starts to apply now??

    • Will Hartfield says:

      Onion juice is not a magic cure. You will need to do more than that to re-grow all the hair you’ve lost in the past 3-4 years. The most important point is that you fix the root cause of the hair loss and then use onion juice to speed up the recovery.

  • Atignas says:

    I am applying this onion juice only for two days. And what i found more hairfall while rinsing with herbal shampoo

  • James Hold says:

    Iv been balding from the crown and temples for the past few years.
    But onion juice use for the past 2 months has done amazing results..
    I have noticed new hairs on the crown spurting out and feel like bristles. This has been long when they were there.
    I can honestly say onion juice therapy is the ultimate solution to all hair loss issues.

    • Fernando says:

      Hello how has it worked out for you ? I just started with the oj 3rd time and since the first time i stopped easily shedding i used to run fingers through my head and pieces of hair will be on my hand since this 3 time i noticed much much less shedding i wanted to know if you were actually able to regrow hair where it was totally gone or just strengthen hair that was already there thank you

  • Darijan says:

    If I’m not able to juice the onion is it ok if I put it in a blender to get it to really small pieces, add a bit of warm water and then the honey?

    • Will Hartfield says:

      That is probably quite a good alternative. You can also try removing the fibre after blending using a muslin cloth.

  • Mark says:

    Hello there. I want to know.. I’m allergic to sulfur and unions contain sulfur. What other remedies are method can I use for hair loss.

    • Will Hartfield says:

      Hi Mark, onion juice wouldn’t be the first thing I recommend for hair loss, in fact I don’t really recommend it at all, since there are better (and less messy) solutions available. For example, instead I would recommend a mixture of magnesium oil and peppermint oil applied to the scalp.
      However, please keep in mind that topical mixtures (mixtures applied to the scalp) will only have a very minor effect on your hair health. There are much more important things to focus on.

  • Nitesh says:

    Sir, i am male 25 having scalp Psoriasis for which i have consulted doctor as well but not yet received any satisfactory result. From last 2 years i am losing my hair but i have observed drasting change in this two months in which i almost leave 30 to 40 hair daily and i am looking totally bald. Will onion juce help me? Also guide me about mixture of onion juice and rum. Thank you

    • Will Hartfield says:

      You need to change your body from the inside-out. Thinking that any topical treatment will fix your problem entirely is not wise. Firstly change your diet and then use a topical treatment like Gro2 to stimulate regrowth. Onions way help, but they aren’t the best option.

  • vin says:

    Hi – once applying the onion juice how long do you leave it in before washing your hair? Is the onion juice more effective if you leave it in your hair for a longer period of time?


    • Will Hartfield says:

      Hi Vin, I would suggest that there are better topical treatments than OJ. For example, peppermint essential oil is actually proven to help hair regrowth (faster than minoxidil) whereas onion is basically unproven.

      • hussain says:

        Is it true😲

      • Suma says:

        I think so onion works. I m nearly 40 now n20 years back I used a hair colour to the front part of my scalp and that whole part started growing grey. Since then I started colouring that part and eventually other hairs too started growing grey. now from past some weeks I started onion juice and I really can see a difference in reversing grey hair. There are lot of black hairs growing too inbetween grey. I’m happy… Before my front scalp would look as if I had painted that part with a white paint now I see a lot of

  • hussain says:

    My dear friends apply daily for result in a month…its true😊

  • Peter says:

    What about grey hair? Do you believe that any of your tips Will help hair reversing his color?

    • Will Hartfield says:

      Hi Peter, I haven’t looked into this at all, though it would be an interesting subject to study. I did hear that the Japanese population of Hawaii is well known to go grey earlier in life then the same age Japanese living in Japan. Apparently the anecdotal reason was diet related.

  • Marco says:

    Hi Will,

    What kind of onion you recommend; the red ones or not? Can I apply onion juice is I have seborrheic dermatitis? How long do you recommend applying?

    Thank you very much

    • Will Hartfield says:

      Hi Marco, I actually don’t recommend onion juice. It may work, but there are better topical alternatives available, so why not use those instead. Please read our free eBook – Scalp Secrets for more details.

      • Marco says:

        Hi, I’ve read all about it! It’s brilliant, but I don’t understand how have I to apply ACV in my scalp, I mean what proportion.

        By the way, I have seborrheic dermatitis; Can I use ACV or GRO2? I would like some advice to treat oily scalp.
