Today, we hear about handmade mixtures produced with raw onions using natural remedies to control frequent and excessive hair fall. Science has shown that onion juice can help with hair loss. For one, it is a rich source of sulfur, an element our body needs, and secondly, it has antioxidants for hair growth. So if you are wondering, “Is onion good for hair?“, let us tell you more about it. 

Why is Onion Good for Hair Growth?

Onions are far more valuable than just being categorized as a vegetable. They are useful for more reasons than just adding flavor and aroma to the food. For instance, onion oil can help you have well-nourished hair strands with stronger roots and a lustrous sheen. 

It is rich in nutrients like potassium, vitamin C, B9, B6, and other components. Regularly using onion is good for hair growth as it treats scalp irritation, fungal growth, and infections. But, of course, everything depends on the results you desire to achieve.

Did you know? Utilizing a highly nourishing hair oil is the secret to having a healthy scalp environment. It is best if your hair oil is devoid of any toxic or harsh chemicals and provides you with nature’s benefits.

How is onion hair oil good for hair care?

1. Boosts hair growth– The main advantage of using onion oil is that it promotes new hair growth. It is best for treating most causes of hair fall, including hair loss brought on by inflammation or bad lifestyle choices.

Sulfur, a substance found in onion oil, is crucial for synthesizing collagen, a protein needed for maintaining healthy hair. Additionally, onion oil helps increase blood flow to the hair follicles, which promotes healthier hair growth.

2. Strengthens hair- Onions are a great source of potassium and vitamins (B6, B9, and C) that help strengthen the hair roots. Additionally, onions are rich in sulfur which is found in keratin. Keratin helps make our hair stronger and more voluminous. 

Numerous factors, including hormonal imbalance and environmental pollutants, may contribute to hair thinning. Onion oil nourishes the scalp and helps your hair follicles remain strong and active. It also protects hair against split ends and breakage.

3. Treats infections– The ancient Ayurvedic literature suggests that onion oil helps improve the scalp environment. All parts of the red onion plant are known for their medicinal properties in Ayurveda. Onions include a variety of phytochemicals that protect against free radical damage. 

Onion oil’s antibacterial properties treat scalp infections like ringworm, folliculitis, seborrheic dermatitis, or psoriasis. Using onion juice on hair also helps to stop the spread of the infection. 

4. Improves overall hair health – According to several experts, onion oil is beneficial for maintaining healthy hair. It effectively moisturizes hair for the longest time and makes hair shinier. 

Furthermore, potassium, which is abundantly present in onion oil, has various benefits for hair. It promotes blood circulation, minimizes breakage, supports the scalp’s pH balance, and encourages conditioning of the hair shaft.

5. Rich in antioxidants– Onions’ abundant antioxidant content prevents damage from free radicals. When your hair is exposed to large amounts of free radicals, they age faster, resulting in premature graying. 

As a result, onion oil is good for hair exposed to pollution, dust, and UV rays. According to hair care experts, the antioxidants in onions make them naturally effective in repairing various types of scalp and hair disorders.

6. Addresses premature aging- Hydrogen peroxide is one of the harmful chemicals used to bleach hair. Our hair naturally produces hydrogen peroxide, but when its levels increase, it damages the roots of the hair. This is what leads to oxidative damage to the hair shaft.

The three enzymes our body produces to rid itself of additional Hydrogen Peroxide are Superoxide Dismutase, Glutathione Peroxidase, and Catalase. To repair the harm done to the hair follicle, onion oil speeds up the growth of these enzymes.

7. Enhances blood circulation- We forget an important aspect while discussing good hair. The area around the scalp is primarily responsible for the hair’s health. And what can enhance this health?

By applying oils or hair serums composed of onion juice, the speed of blood circulation in the scalp can be optimally accelerated. A strong blood flow means that the scalp area will naturally be healthy for hair growth. 

How to use onion oil for more benefits?

You can extract the juice of little onions at home or get products made with the goodness of natural components. However, to get the immediate advantages of onion oil, ensure your product does not contain harsh chemicals. 

  • Be careful to get to the roots by massaging your scalp for 15 to 20 minutes.
  • Use your fingertips to apply gentle strokes to your scalp, moving in small circles.
  • Let the oil stay on your scalp for two-three hours. You can also let it stay overnight before cleansing it with a sulfate-free shampoo.
  • To see results quickly, repeat the activity twice weekly.

To get the most out of your onion hair oil, mix them with your favorite essential oils, such as natural coconut or castor oil for hair. Mixing hair growth oil with your regular onion oil will deeply nourish your scalp, strengthen the roots, and promote new hair growth.
