What is Causing Hair Loss?
Hair loss is a natural process in every human. However, premature hair loss can lead to balding and hair thinning. Hair loss accelerates for different reasons, but you can almost always trace it back to one of these factors:
Genetic factors: Hair loss can be inherited from your parents.
Hormonal changes: Due to pregnancy, childbirth, menopause, or an imbalance of thyroid hormones.

Medical conditions: Certain medical conditions can cause hair loss, such as alopecia areata, scalp infections, chemotherapy drugs, and blood thinners.
Physical or emotional stress: Overstressing may cause hair to enter the resting phase (telogen) and fall out.
Nutrient deficiencies: A lack of certain nutrients, such as iron and protein, can cause hair loss.

Hairstyles and treatments: Hairstyles that pull on the hair can cause hair loss. Using harsh hair care products or heating tools can also damage the hair.
How is Onion Juice good for Hair Loss?
Onion juice is one of the oldest natural remedies for hair loss and other hair issues. Different cultures have traditionally used onion juice for hair care. Modern science tells us that onion juice is rich in sulfur, which is an essential nutrient for hair health.
Here are the main benefits of onion juice for hair:
Promoting hair growth: Sulfur is an essential component of keratin, the protein that makes up most of our hair. By providing the body with a rich source of sulfur, onion juice helps stimulate hair growth and prevent hair loss.
Reducing dandruff: Onion juice has antimicrobial properties that can help reduce dandruff and other scalp infections. Dandruff, in turn, can contribute to hair loss.
Strengthening hair: The high sulfur content in onion juice strengthens hair strands, making them less prone to breakage.

Improving blood circulation: Onion juice may help improve blood circulation to the scalp, which is essential for healthy hair growth.
A combination of these benefits makes onion juice the perfect ingredient for better hair health. If you're struggling with weak and breakage-prone hair, consider including onion juice and other onion-derived ingredients in your hair care routine.
Why onion juice is good for your hair
Onion juice is made of a complex mixture of water, proteins, carbohydrates, fiber, vitamins, and minerals. The specific chemical composition of onion juice will depend on the type of onion used.
Among other things, onion juice is rich in proteins, minerals, and vitamins. Onion juice contains small amounts of proteins, including amino acids such as cysteine – a sulfur-containing amino acid. It also contains several vitamins, including vitamin C, vitamin B6, and folate.

But most importantly, onion juice contains sulfur – an essential mineral for healthy hair growth. Sulfur gives onion juice much of its healing properties. Onion juice also has significant amounts of potassium, calcium, and magnesium.
Here's why sulfur is such an essential ingredient for your hair:
Sulfur and onion juice
Sulfur is an essential mineral vital for the proper functioning of many systems in the body, including the hair. It's a component of keratin, the protein that makes up most of our hair. Sulfur strengthens the hair shaft and improves hair's elasticity, making it less prone to breakage.
Sulfur is also involved in the production of collagen. Collagen helps to give hair its strength and elasticity, and a collagen deficiency can lead to thinning hair and hair loss.
In addition, sulfur improves blood circulation to the scalp, eventually promoting healthy hair growth. It can also help prevent dandruff and other scalp infections. Many people notice a reduction in hair fall after using onion juice because their hair fall was mainly due to dandruff.

Overall, sulfur is an essential nutrient for healthy hair. Sulfur is naturally found in various foods, including onions, garlic, eggs, and nuts. Sulfur deficiency can cause problems in your health, including hair health.
How to use Onion Juice for Hair Loss?
Convinced about using onion juice on your hair? There are two main ways to do it. You can DIY if you have the time and expertise or buy all-natural hair care products infused with onion juice.
DIY onion juice
To make onion juice at home, you will need the following ingredients:
- One or more onions
- A blender or food processor
- Cheesecloth or a fine-mesh strainer
Here are the steps to follow:
- Peel the onions and cut them into small pieces.
- Place the cut onions in a blender or food processor and blend until you have a smooth purée. You may need to add a small amount of water to help the blender process the onions more easily.
-
Strain the purée through a cheesecloth or fine-mesh strainer to remove any solid pieces. The resulting liquid is your onion juice.
There are many ways to use onion juice on hair and scalp. You can also use raw onion juice directly on your scalp. Alternatively, you can make hair packs by combining onion juice with aloe vera, honey, yogurt, castor oil, etc.
What are the ingredients in onion oil?
Store-bought onion hair oils should ideally contain 100% pure, cold-pressed oils, like this Wow Skin Science Onion Black Seed Hair Oil. It also has almond, coconut, olive, jojoba, and castor oils. When combined with other potent natural oils, onion oil becomes even more effective.
