Your hair needs to be nurtured with good ingredients to maintain its glory, and onions and garlic are an age-old remedy to help you achieve this.
Ancient Chinese medicine and Ayurveda have recorded the multiple benefits of onions and garlic for the body.
This article will give you enough reasons to make onion juice and garlic a part of your hair regimen.
How Onion Juice and Garlic Are Useful to the Hair
Raw garlic is rich in sulfur, which is essential for hair care as it is the foundation of keratin, the protein needed for good hair growth.
Garlic is also abundant in vitamins and minerals that provide nutrition to the hair follicles. The vitamin C in garlic boosts collagen production and is vital for healthy hair growth.
The selenium in garlic promotes blood circulation to the hair follicles so they can produce healthy hair. The calcium in garlic helps in strengthening the structure of the hair.
Use garlic in hair masks and oils with onion juice, coconut oil, fenugreek, etc., to nourish your hair. (1)
Onion juice, like garlic, is also abundant in sulfur and is helpful for hair growth. It provides anti-inflammatory and antioxidant benefits because it has high amounts of quercetin, which fights against free radicals, air pollutants, and toxins that cause damage to hair cells leading to hair loss.
Many hair care companies produce onion juice and garlic juice for the public to purchase, but you can also easily prepare them at home and use them to get healthy tresses.
Benefits of Using Garlic Juice for Your Hair
1. Helps treat alopecia areata
Garlic has fantastic properties that promote hair growth. It contains calcium, zinc, selenium, and other minerals that boost hair health. Its antimicrobial properties are suitable for the scalp and prevent dandruff. (2)
A research study has shown that the continuous usage of garlic gel on the scalp added to the efficiency of using topical betamethasone valerate for the treatment of alopecia areata. (3)
2. Fights dandruff and fungus infections
The components in the garlic have antifungal and antimicrobial properties that protect the scalp from fungal infections and keep it clean so that hair growth can happen naturally. (4)
3. Maintains scalp pH
Like onions, garlic is also rich in sulfur, which stimulates hair growth and maintains the pH level of the scalp. Applying garlic juice nourishes the scalp and makes the hair robust and shiny. (1)
4. Protects from UV rays
UV rays harm your hair and damage the hair follicles. Research confirms that garlic contains antioxidants that serve as a protective layer against UV damage and pollution.
It also cleanses the hair follicles and prevents clogging, thus reducing damage. (5)
5. Prevents hair loss
Garlic is rich in vitamin C, which is essential for hair growth and collagen production.
The high amounts of selenium in garlic help in improving blood circulation to the hair follicles so that they are well nourished, preventing hair loss and breakage. (1)
Precautions When Using Garlic Juice on Hair
- Pungent smell: Garlic juice has a pungent smell that does not go away easily. It is recommended to wash your hair 30 minutes after applying the liquid.
- Sensitivity: If you have a sensitive scalp, apply garlic juice cautiously as using this liquid on exposed skin can cause skin irritation.
How to Prepare Garlic Juice?
- Take a handful of garlic cloves, wash them, and pat them dry.
- Lay the garlic cloves on the cutting board and remove their skin.

Benefits of Onion Juice for Your Hair
1. Stimulates hair growth
Human hair is made of keratin, a protein that has high sulfur content, and onion is abundant in this mineral. Therefore, it is beneficial for your hair strands as it adds strength and elasticity to them. In its absence, your hair can turn brittle and fall off easily.
Studies conducted on the benefits of onion juice versus tap water for hair regrowth have shown that consistent application of onion juice among the participants resulted in a higher percentage of hair growth in comparison with those using only tap water. (6)
2. Improves blood circulation
Another reason onion juice has become a popular remedy to achieve hair growth is it contains flavonoids and quercetin, which are helpful in improving blood circulation to the scalp, leading to hair growth. (7)
3. Strengthens the hair
Hair quickly absorbs the harmful UV rays, dust particles, free radicals, pollution, etc. These factors deteriorate the protein in the hair and make it weak. To make matters worse, scalp dryness, dandruff, and other problems can ensue.
Onion juice is rich in antioxidants that fight free radicals and protect you against factors that cause hair aging. (8)
4. Tackles scalp disorders
Onion juice has antimicrobial and antifungal properties that treat dandruff and other hair and scalp-related issues that lead to hair fall and breakage. (9)
5. Reverses premature graying
Onions contain vitamins, minerals, and other antioxidants, including catalase, that reduce the hair’s oxidative stress that is responsible for premature graying of hair.
6. Acts as a hair conditioner
Regular massage with red onion juice nourishes the scalp and conditions the hair, preventing dryness and frizz, thus improving hair growth.
