To encourage hair growth

There are people who are naturally gifted with fuller hair. But there are others who constantly battle with falling hair and stunted growth. And it seems like no matter how hard they try to tackle it – the condition will never change.

It is important to note that onion juice has been successfully used for decades to stimulate hair growth. And this is due to the fact that the plant is rich in sulfur.

Sulfur plays a vital role when it comes to hair growth. In fact, it is dubbed the main building block of hair. Because it improves blood circulation as well as providing the hair follicles with enough nourishment.


Recent studies have also shown that onion is endowed with a lot of anti-bacterial properties, and these anti-bacterial properties are known to help combat scalp infection that contributes to hair loss.

However, it is important to highlight here that according to a 2002 study about the use of onion juice for hair loss published by the Journal of Dermatology, participants who applied onion juice twice daily for the period of two months experienced much better hair re-growth rates compared to those who only used tap water.

In the study, hair regrowth was observed in 87% of patients treated with onion juice. Aside applying onions juice to your hair for rapid growth and stronger hair, eating onions regularly can actually encourage the hair growth process.

The more onions you eat by adding them to your diet, the more your chances of having healthy hair. Although eating onions is not as effective as applying onion juice to the hair.

  • gathering 100 grams (about 3.5 ounces) of fresh onion bulbs
  • cutting them into small pieces
  • using a food processor to chop the onion into even smaller parts
  • filtering the onion extract by pouring the chopped onion over a muslin cloth

Then added the onion extract (usually anywhere from 1 to 3 milliliters) to a natural shampoo of coconut, castor, and eucalyptus oils as well as cleansers.

You can use this same process to add onion extract to your own shampoo
Even if you’re not ready to start making shampoos, you can use the same process the researchers used to make an onion extract to add to your own shampoo at home.

Don’t worry, your hair won’t smell like onions

And if you’re wondering whether your hair will smell like onions indefinitely, there’s good news.

The researchers used fragrances and a small amount of lemon juice to conceal the smell. When they used the shampoo, they didn’t note a “characteristic smell” of onions.

To reverse graying of hair

No peer-reviewed evidence exists on the concept of onions reversing the process of graying hair. However, a lot of home remedies promise onion extract can help reduce gray hairs.

The idea behind these home remedies is that onions contain an antioxidant compound called catalase that helps reduce hydrogen peroxide at the hair roots. This is thought to keep the hair from turning gray.

If you’re willing to give this home remedy a try, here’s a mixture that you can apply three to four times per week:

  • Combine 3 tsp. onion juice with 2 tsp. lemon juice.
  • Apply mixture to hair and scalp as evenly as possible.
  • Leave on hair and scalp for 30 minutes.
  • Rinse and use mild shampoo to reduce any onion smells.

Alternatively, you can soak a cotton pad in plain onion juice and apply the juice to your scalp, massaging as you apply it. Rinse with mild shampoo after 15 minutes.

To calm a dry, itchy scalp

Onion’s anti-inflammatory properties may help soothe an itchy scalp. You can also combine onion extract with other natural ingredients to calm your scalp.

Some combinations to try:

  • 2 tbsp. onion juice and 1/2 tbsp. raw honey
  • 1 tsp. olive oil and 3 tsp. onion juice
  • 3 tbsp. onion juice, 5 tsp. coconut oil, and 1 tsp. lime juice

You can apply one of these combos to your scalp, then wash it away with a mild shampoo after about 20 to 30 minutes.

To quell dandruff

Onion juice has antimicrobial and antifungal properties, which is why some natural health experts advocate for it as an infection treatment.

Many people experience dandruff due to a fungus called Malassezia furfur, so onion’s antifungal properties could definitely come in handy as a dandruff fighter.

Because there isn’t a lot of research on onion as a dandruff fighter, though, it’s not really a first-line treatment for moderate to severe dandruff. If you have the occasional flakes, however, you could try applying onion juice to your scalp.

You can also experiment with potential dandruff-fighting combinations.

Examples include:

  • grinding 2 tbsp. fenugreek seeds and soaking them in 2 tbsp. onion juice and water to make a paste, then applying to your scalp for 30 minutes before rinsing off
  • mixing 2 tbsp. aloe vera gel and 3 tbsp. onion juice, then applying to your scalp for 10 minutes before rinsing off

If your hair is super smelly after using an onion juice preparation, you can follow up with a mild shampoo and apple cider vinegar rinse. To do this:

  • Pour 2 tbsp of apple cider vinegar into 1 cup of water.
  • Rinse the solution through your hair when you finish showering.
Possible side effects of using onion on your skin

Using onions on your skin isn’t a good idea if you’re already allergic to onions you eat. Steering clear may help you avoid further allergic reactions.

Also, if you have sensitive skin, it’s possible that onion juice could irritate it. The key is not to leave it on too long. This means keeping it on overnight is a no-no if you do happen to have sensitive skin or a sensitive scalp.

As with any product or treatment, if onion extract irritates you, stop using it.

Key takeaways

You can use onions to improve your hair in lots of ways. These include reducing dandruff and potentially promoting hair growth.
