Onion Juice for Hair Loss and Alopecia: It Works Magic

How to Use onion juice for hair growth


It’s been my random observation that men and women who eat raw onion with their meals have thick beautiful hair. And they also do not grey early.

It seems there is a connection between onion and good hair.

Onions are packed with two amazing ingredients – Sulphur and Quercetin that can help boost hair growth.

Our hair is made up of a special protein called keratin – which is high in sulphur. The presence of sulphur gives hair its strength and elasticity; while its lack may cause weak, brittle hair that is easily broken. Sulphur also boosts blood circulation, bringing oxygen and nutrients to scalp – so hair can grow healthy and strong.

Onions are also surprisingly high in plant nutrients called quercetin – this is a powerful antioxidant and anti-inflammatory. It helps to get rid of free radicals which can harm the cells of the body (including hair cells). It also protects our hair and skin from air pollution and other toxins.

Besides, onions are a good source of biotin (often touted as the ‘hair growth vitamin’), flavonoids, manganese, copper, vitamin C, phosphorous, and folic acids – all very important for healthy and shiny hair.

It has been scientifically shown that topical application of onion juice can help with hair loss. A study published in the journal of dermatology looked into the use of onion juice for alopecia areata (an autoimmune condition that causes patchy hair loss). Within six weeks of using onion juice, 86.9% of participants experience new hair growth in the bald spots. Men had better success with this treatment than women.

This study has its limitations: there were only 38 participants, and a follow-up study was never done to see if the results can be repeated in another group of people.

But then who is going to sponsor such cost extensive research as there is no product to sell and no profits to be made.

The good news is that there is ample anecdotal evidence to support onion juice benefits. I have heard from family and friends that onion juice can promote thick hair growth. Also, I have read hundreds of comments online where many people were singing praises for onion.

You can do your own study by trying out onion juice on your hair. Here’s how….

How to Use Onion Juice for Hair Growth

Eat onion for hair growth

Eating onion is one way you can get its hair nourishing benefits.

You can also apply onion juice on your scalp to remedy hair loss. In fact, onion juice hair mask has been used since ancient times. It even helps to reverse grey hair and makes your hair grow faster, softer and shinier.

There are 5 ways you can use onion juice on your hair.

1. Onion Juice Hair Mask

This is the most simple way to use onion juice.

You will need:

  • 1 large onion
  • 3 to 4 drops of lavender essential oil (optional)


Peel the onion and cut it into small pieces, then put them into the blender and blend until smooth paste. Next, strain the mixture and squeeze out as much juice as possible.

You can also use a grater: peel the onion and grate it, and then strain the mixture to get just the juice.

Add lavender essential oil to the onion juice.

How to use: Massage the juice into your scalp and leave it on for 15 to 30 minutes, then rinse it out and wash your hair using a natural cleanser.

How often to use: you can apply this remedy once or twice a week. It can take 3 to 4 months to produce any visible results.

Tip: If you have a dry scalp its best to use onion juice along with coconut oil or olive oil (see below).

Note: If you are using onion juice for the first time do a patch test on a small area in case you may be allergic to it.

2. Onion Juice with Coconut oilonion and coconut oil for hair growth

Onion juice when mixed with coconut oil works really well to reduce hair loss. Not only is coconut oil moisturising to the scalp, it provides extra nourishment to the hair follicles. Plus its healing effects protect the scalp against microbes that can limit hair growth.

You will need:

  • 1 tablespoon onion juice
  • 1 tablespoon coconut oil
  • 2 to 3 drops rosemary essential oil (optional)


In a bowl, put coconut oil. If your coconut oil is in a solid state, place the bowl in hot water until it turns to a liquid. Then add onion juice and rosemary essential oil and mix well.

How to use: Apply this mixture into your scalp. Massage gently for 3 to 4 minutes and let it sit for 20 to 30 minutes. Then wash as usual.

How often to use: you can apply this remedy once or twice a week.

Coconut oil alternative: you can use olive oil instead of coconut oil or use both together.

3. Onion Juice and Egg Hair Mask

Onion smell can be a put off for many people. Using egg with onion will help mask the smell to a great extent. Plus, the egg itself is like a multivitamin for hair. Egg contains amazing fatty acids which add shine and lustre to your hair. Plus, the proteins in eggs thicken the hair shaft, and its vitamin A, D and B12 promote healthy hair growth.

You will need:

  • 1 tablespoon onion juice
  • 1 egg
  • 1 tablespoon castor oil (optional)
  • 1 tablespoon olive oil (optional)
  • 2 to 3 drop rosemary or lavender essential oil (optional)


Place the egg, onion juice, (olive oil, castor oil and rosemary oil) in a bowl and whip them all together until well combined.

How to use: Apply the mixture on your scalp and hair. Cover your hair with a shower cap or you can wrap a cloth around your head, and leave it on for 20 to 30 minutes. Then it rinse off and wash your hair with a natural shampoo, and let it dry naturally.

How often to use: Do this mask once a week

Dry hair Tip:  If your hair is dry and brittle, then use just the egg yolk (read here).

4. Onion and Honey Hair Maskonion and honey for hair loss

You can also use onion juice along with honey. This is especially beneficial for those with dry, brittle hair. Honey is a great moisturiser and will make dry hair soft, smooth and less frizzy. Plus, the antiseptic properties of honey help with dandruff and soothe an itchy irritated scalp.

You will need:

  • 1 tablespoon onion juice
  • 1 tablespoon raw honey
  • 1 tablespoon olive oil


Place all the ingredients in a bowl and mix well. Massage this mixture into your scalp and leave it on for 20 to 30 minutes, then wash as usual.

How often to use: you can apply this remedy once a week.

5. Onion Juice and Henna for reversing Grey Hair

Onion juice also works great to restore your natural hair colour. It contains a potent enzyme Catalase, which quickly neutralises the colour damaging molecules from the hair.

You will need:

  • 1 tablespoon onion juice
  • 5 to 6 tablespoon henna
  • 1 tablespoon olive oil
  • Black tea (enough to make a paste)

Optional add-ins

  • 1 egg (conditions and adds shine)
  • 1 tablespoon yogurt (moisturises and softens hair)
  • 1 teaspoon lime peel powder (helps with dandruff)


Place henna in a bowl, pour black tea to make a smooth paste (you can also add 1 tablespoon lime juice). Cover and keep it aside for 6 to 10 hours for the dye to release.

Just before you are going to apply add olive oil, onion juice, (egg and yogurt) to the henna paste and mix well.

How to use: Apply to your scalp and hair, slather the mixture to your entire head. Cover your hair with a shower cap (or you can wrap a cloth around your head), and leave it on for 1 to 2 hours. Then rinse off and wash your hair with a natural shampoo.

Air dry your hair: I can’t stress enough …how important air drying is for beautiful naturally wavy hair.

How long will it take to see results: give it at least 3 to 4 months.

But if you think onion juice is making your hair fall worse then stop using it. Not everyone gets lucky with onion juice. For some people it does nothing.

But there is no harm in using it for a few weeks to see if works for you or not. It’s not expensive, it’s not difficult to get. So give it a try and you might be the lucky one.

Enjoy your thick beautiful hair 🙂

I started these supplements with fresh onion juice hair mask as waking up in the morning and take the onion juice and apply to scalp barehanded and brush my teeth and this supplement on empty stomach.I guess its works for me and I feel my hair is thicker now.
