There is a humble ingredient in our kitchens that surprisingly has many benefits for our hair. Essential in preparing a wide variety of dishes, an onion is great for your hair as well. 

Onion juice consists of sulfur, which is found in amino acids of protein cells as well. Protein, especially Keratin, is the main component of hair and nails. As such, onion oil, which is made from the extracts of onion juice, is immensely beneficial for hair.

It promotes collagen production, which is responsible for skin and hair rejuvenation, boosts blood circulation and helps in maintaining the overall health of hair follicles. 

This blog will look at all the benefits of onion hair oil and how onion oil can be used at home to promote hair growth.

A word of caution may be warranted here. There is no study to prove that onion oil is also beneficial for hair treatments for serious ailments like advanced stages of pattern baldness and severe auto-immune diseases like alopecia.

For advanced stages of hair fall, you should consult our hair experts at an Advanced Hair Studio near you. 

Can Onion Oil Cure Baldness?

This matter needs to be scientifically probed. There is no doubt that onion oil for hair is greatly beneficial. Onion belongs to the Allium species and is one of the oldest cultivated vegetables in the world. It has been used as a spice in cooking, and as an ingredient for preparing medicines and curing various diseases.

Like other vegetables of the Allium family, onions are known for their pungent flavor and easy storage. The smell and flavor of an onion comes from the natural sulfur compounds that are found in all the vegetables.

Sulfur is the key ingredient found in Keratin. It is the third most abundant mineral found in the human body after calcium and phosphorus.

Having a sulfur-rich diet helps in Keratin synthesis that is crucial for hair growth. On the other hand, lack of sulfur makes hair dry and brittle that leads to hair fall.

Therefore, the benefits of onion oil for hair growth and curing baldness are immense. Regular use of onion oil on the scalp prevents hair breakage and split ends and makes hair stronger.

People who are suffering from initial stages of baldness may incorporate onion oil in their daily hair care routine.

Can I Leave Onion Juice on My Hair Overnight?

Benefits of Onion Hair Oil

For the best results, onion juice extracted from fresh onions should be absorbed properly by the scalp. Therefore, you should leave onion juice on your hair at least for a couple of hours. Even better, apply onion juice on your scalp and leave it overnight.

You can rinse with water in the morning and wash your hair with a mild shampoo so that no residue of onion extract is left on your scalp.

Can I Use Onion Oil Daily?

Any hair care routine takes time and consistent effort to see promising results. People often give up too easily when they fail to see any noticeable results within a few days.

However, experts recommend that any new hair treatment needs to be followed at least for a few weeks before any positive results can be seen. If you are planning to use onion oil for hair care, then make sure you apply it to your scalp daily for at least a couple of weeks. 

However, there are several other professional hair care products that you can give a try. For instance, our Carl Howell Haircare Products range features the Advanced Revitalizing Complex - a strengthening and reconditioning complex for hair and scalp.

5 Surprising Onion Hair Oil Benefits

Here are the top 5 onion oil benefits:

1. Antimicrobial Properties

Onion oil has natural antimicrobial properties that help in preventing the natural build-up of oils, chemicals and DHT on your scalp. Further, onion oil can help you fight infections and make your hair stronger.

2. Antioxidants

Onion is also rich in antioxidants like Flavonoids. Flavonoids are versatile compounds that reduce the presence of free radicals in your body.

Free radicals are molecules that advance the aging process, including hair thinning and hair fall. Regular use of onion oil helps in decreasing free radicals in your body and promoting hair growth.

3. Anti-inflammatory

Onions also have anti-inflammatory properties. Onion oil reduces inflammation and creates an environment that promotes hair growth.

4. Blood circulation

Blood circulation is crucial for the growth of new hair. Onion hair oil promotes blood circulation that strengthens the hair roots and leads to the growth of new hair follicles.

5. Conditioning

Onion oil, when mixed with other suitable hair oils like castor oil or coconut oil, helps in conditioning the hair and prevents premature graying. It gently nourishes the hair and prevents dry and frizzy hair.

How to Use It?

Onion oil can be used in many ways. Firstly, it can be used directly on the scalp and left overnight for the best results. Secondly, it can also be used in combination with other hair oils for men and women. This way, you can optimize the benefits that you get from different kinds of oils.

Finally, onion juice can be mixed with your shampoo for cleaning the hair. For faster results, onion hair oil should be used twice daily (once in the morning and once in the evening) for several weeks before any tangible results can be seen.


This blog highlighted the key benefits of onion oil. From anti-microbial properties to anti-inflammatory qualities, from preventing infections to Keratin synthesis, the list of benefits from onion hair oil is staggering.

However, it is important to note that onion hair oil may not be effective in curing severe forms of male or female pattern baldness and Alopecia Universalis or Totalis. In alopecia, the immune system attacks its cells leading to miniaturization of hair follicles and halting hair growth.

In such severe cases, you should take the Advanced Hair Check and consult our hair experts. We will suggest appropriate hair treatments for you.

I am honestly thankful to Advanced Hair Studios. I suffer from a hair-pulling disorder. There is this constant urge to pull off your hair follicles. It is painless when you pull but extremely painful when you see a missing patch on your scalp. But, I feel blessed with AHS hair fall treatment. I can see baby hair growing. It’s been two weeks. All I can see is low hair fall.

I have done my hair transplant surgery in AHS Delhi Branch on 2019 by travelling to Delhi from Dhaka, Bangladesh. The front and the back portion of my head were bald and through the hair transplant surgery, they have managed to cover the front portion of my head and the former appearance of my face returned back. The way they collected hairs from the donor portion did not affect my donor area at all. I am quite happy with my result. I have been consulting with them for a second seating so that they can cover the back portion of my head as well so that the hair density on top will increase and the bald portion of my head will reduce to a minimum level.
