1. Promotes hair growth

Regularly using the best onion hair oil is thought to nourish the scalp, encourage hair growth, strengthen the roots, and prevent hair loss. Massaging onion hair oil for hair growth into the hair and scalp increases blood circulation in the hair follicles, making your hair appear denser and thicker. Red onion oil is an effective Ayurvedic therapy for preventing hair loss and growing a thicker mane.

2. Treats dandruff

Essential red onion oil's intense antibacterial and antiseptic characteristics assist in preventing dandruff and curing scalp diseases from the source. The best onion hair oil contains bioactive ingredients that feed the hair follicles, reduce hair loss and breakage, and provide volume and strength to the mane.

3. Delays premature greying

Nutritional deficiencies, stress, medical conditions, and even heredity can cause premature greying of hair. Onion oil includes enzymes that can help prevent free radicals from harming your hair, darkening it and restoring it to its original colour/shade.

4. Rich in antioxidants 

The best onion hair oil in India contains naturally powerful antioxidants such as flavonoids, which help minimise free radical presence in our bodies. The free radicals promote rapid ageing and cause hair loss and fall. Therefore, onion oil for hair decreases premature greying and promotes hair growth. 

5. Antimicrobial properties

Onion oil has antimicrobial and antibacterial characteristics, making it helpful in keeping your hair clean and treating scalp infections. Ayurvedic onion hair oil also inhibits the development of oil, chemicals, and DHT, which can damage the hair's natural texture. This hair oil contains bioactive ingredients that help decrease hair thinning while nourishing hair follicles, providing strength and volume to your locks. 

6. Avoid split ends

Damaged hair is an unavoidable hair issue. Split ends are one type of hair damage that causes it to seem dry and lifeless, with breakage at the ends. We frequently clip the ends to relieve the damaged hair strands. This is not a great solution, however. Red onion hair oil has several advantages, including repairing hair damage. 

This is when we use the oil to heal damaged hair and split ends, giving your hair a revitalised appearance. Onion contains sulphur, which naturally softens and cures broken ends. It rejuvenates and restores hair follicles. This also enhances the hair's volume, relieving dull, damaged hair with split ends.

7. Natural conditioner

Though shampoos and conditioners are associated with hair smoothness, onion oil is a natural option for conditioning your hair. Aside from promoting hair development, this oil has natural conditioning properties. It may be used as a light conditioner before shampooing to keep hair smooth, which may be affected by shampoo use. Onion oil is a conditioner, ensuring your shampoo does not remove your scalp's natural oiliness.

8. Shine and bounce

You have come to the correct spot if you seek an alternative technique to cure your damaged and dull tresses. It adds shine to your hair and keeps it bright and silky all day. Regular use of this oil gives your hair energy and smooth texture, resulting in excellent hair days every day.

Things to know before using Onion Hair Oil

  • Easy to make at home and devoid of harmful chemicals.

  • Before administering to the entire scalp or hair, conduct a patch test on a small outer skin area.

How do you use onion oil on your scalp and hair?

The simplest way to ensure that you get the immediate benefits of onions without using additional chemicals is to extract the juice from little onions at home. Place a few drops of onion oil in your palm to cure baldness and massage it into the scalp for at least 15 minutes. After allowing the oil to sit in your hair for a few hours, wash it off with organic shampoo. 

To get instant results, repeat the process every two days. Combining onion oil with any of your favourite carrier oils, such as raw coconut oil, allows you to reap both benefits. You may massage your scalp and length with hot onion and coconut oil. You must leave it on your hair overnight for the best results and rinse it thoroughly the next day with a mild shampoo.


Some may notice significant results in only a few days, while others may take longer. What we need to know is that onion oil is a natural extract. As a result, the time required to work and produce results may be longer than anticipated. As a result, it is best to regularly apply the hair oil in modest amounts and track development.
