Onion is one of the favorite ingredients of many chefs around the world. It has a strong yet decent taste that accents a lot of cuisines very well.
But you might be surprised that this ingredient can be the star of your hair care regimen too!
Yes, you read that right! According to many hair specialists and user reviews, onion juice has proved to be helpful for managing many hair conditions and is said to promote the growth of hair.
The juice is a treasure chest of minerals and vitamins that nourish the hair and help it grow. Some of these nutrients include potassium, magnesium, vitamin B6, and sulfur.
In fact, nowadays, you can easily find shampoos and conditioners that have onion juice as the main component.
The theory behind the positive action of onion juice on hair is its high sulfur stimulates the formation of a very important hair protein called keratin while also increasing blood flow to the scalp. (1)(2)
Another good thing is you can amplify the benefits of onion juice by mixing it with certain other ingredients to get a synergistic effect.
This article will delve into all the possible ingredients that work well with onion juice to enhance its effectiveness in inducing hair growth.
Ingredients to Mix with Onion Juice for Hair Growth
You can add various natural ingredients to onion juice to stimulate hair growth.
1. Aloe vera gel
While onion juice promotes hair growth by improving blood flow and supporting keratin development, aloe vera gel enhances overall scalp health.
Aloe vera gel has been found to be a great agent for people who wish to control conditions such as itching and scaling, which pave the way for temporary hair loss and significant damage to hair health. (3)
How to use it:
- Take out onion juice from 1 whole onion.

2. Coconut oil
There is no doubt that coconut oil appears on this list because it is a favorite hair oil of many people around the globe. It contains fatty acids, antioxidants, and antibacterial and antifungal agents that keep your scalp healthy and well protected. (4)
It also has a very notable ability to penetrate the hair shaft very deeply to prevent protein loss from the hair. (4)
How to use it:
- Combine 100 ml of coconut oil and ½ cup of onion juice.
- Massage the mixture on your scalp.
3. Honey
Honey is, intrinsically, an antiseptic agent, which means it safeguards your scalp from infections, dandruff, and other issues such as psoriasis.
A healthy scalp is a must for active hair growth, and since honey also keeps your scalp clean by removing any buildup of dirt or dead cells, it can help improve hair growth in combination with onion juice. (5)(6)

4. Castor oil
Castor oil is derived from the plant Ricinus communis and is famously used in many countries as a hair moisturizing agent for hair growth.

How to use it:
- Mix 1 tbsp of castor oil with ½ cup of onion juice.
- Use this mixture as a hair mask.

Eggs have 2 components – the egg white and the egg yolk. The good news is that both of these egg parts can be very useful for the hair, and hence, eggs are a great ingredient to be partnered with onion juice.
Egg yolk is rich in nutrients such as biotin and lecithin, which are known to facilitate hair growth as they hydrate the hair and prevent breakage, (7) while egg white protects the scalp from bacterial infections. (8)
How to use it:

7. Green tea
Green tea is like a sea of antioxidants, which makes it a perfect companion in your hair growth journey. Plus, it is also rich in chemicals called catechins, which facilitate hormonal balance, which further promotes hair health and prevents hair loss.
A study showed that animal models treated with polyphenolic green tea extracts had notable hair regrowth in only 6 months. (11)
Topical application of green tea can also protect you from dandruff, making it a good ingredient to use with onion juice.
