Extract fresh onion juice by blending or chopping onions finely, and straining the pulp with a soft cotton or muslin cloth. Apply the extracted onion juice directly to a clean scalp using your fingertips or a cotton ball.
Applying onion juice consistently to the scalp helps nourish dormant hair follicles and creates a healthy environment for new hair growth. Onion juice is a well-known remedy trusted in many households for decades. But learning to use it in the right way can help you reap maximum benefits from it.
This blog helps you understand how to use onion juice for hair growth, its benefits and the correct method to use it.
Why Use Onion Juice for Hair Growth?
Onion juice is known for its property to improve scalp circulation, fight infections, reduce thinning, and maintain a clear scalp. People often use it for hair growth, to reduce hair loss and even treat scalp conditions like mild dandruff.
The key benefits of using homemade onion juice for hair are:
- Stimulates Hair Growth: The sulfur and antioxidants in onion promote scalp circulation that helps the follicles to grow with consistent use.
- Reduces Hair Fall: With regular use, it can stimulate dormant follicles and produce new hair.
- Reduces Hair Breakage: The sulfur compounds support keratin synthesis, which helps reduce hair breakage and improve resilience to environmental damage.
- Maintains a Healthy Scalp: It helps in fighting off scalp infections and works towards promoting a healthy scalp.
- Improves Shine and Texture: Onion juice helps to combat dullness and rough texture, leaving the hair naturally stronger, softer, and shinier.
Onion juice does not change the structure of hair. It provides sulfur and keratin to strengthen the strands. If you do not see a noticeable difference in 3 months, it is recommended to change your approach and consult a dermatologist to get medically approved treatments.
Does Onion Juice Boost Hair Growth?
Yes, onion juice is quite effective in boosting hair growth and reducing hair fall. However, its efficacy varies considerably from person to person and the underlying cause of hair fall. In clinical studies, onion juice is effective in regrowing hair in people with alopecia areata, an autoimmune condition causing patchy hair loss.
However, there are no studies or scientific evidence to support the effectiveness of onion juice on genetic, hormonal hair loss, and male or female pattern baldness, such as androgenetic alopecia or telogen effluvium - a form of hair shedding triggered by stress or deficiency.
Can You Rely on Onion Juice for Hair Regrowth?
Yes, if you experience normal hair fall or alopecia areata (patchy hair loss) and want to try natural remedies that help boost hair growth while controlling hair loss. However, it is not recommended to rely solely on onion juice for hair regrowth.
Onion juice is not effective at blocking DHT (Dihydrotestosterone), the androgen responsible for hair thinning, fixing hair loss due to nutritional deficiencies, thyroid or other health issues.
Step-by-Step Method to Use Onion Juice for Hair Growth
So you might be thinking how to apply onion juice on the scalp, is there any correct method to it or any particular thing that needs to be followed? The right application is very important when using onion juice on your hair. The onion juice hair growth method that you can follow for effective results is:
- Use Fresh Juice: Extract fresh juice by blending freshly chopped red onions. Use a cotton or muslin cloth to extract the juice in a bowl.
- Apply to a clean scalp: Use a cotton ball or fingertips to apply the juice all over the scalp, then massage it in well.
- Leave it on for 30 minutes to an hour; however, if someone can’t stand the smell of onions, it is advisable to keep it on for 15-30 minutes.
- Wash it off completely: Use a mild shampoo to help clean it off. The odour of onion juice is strong, so it might require using the shampoo twice, depending on personal preferences.
Individuals with a sensitive scalp or those trying this remedy for the first time should always get a patch test behind the ears 24 hours before complete application.

Frequently Asked Questions
Q1 - How to Apply Onion Juice on the Scalp for Hair Growth?
Apply freshly made onion juice to a clean scalp, let it sit for 15-45 minutes, as per convenience, but not more than an hour. Also, double shampooing is necessary to clean the scalp and eliminate the odour of the onion juice.
Q2 - How Long Does Onion Juice Take to Grow Your Hair?
Onion juice roughly takes a month to show visible results, such as a reduction in hair fall and new hair growth. Some people may also see hair regrowth and thickness with consistent use.
Q3 - Can You Wash Your Hair Only With Water After Applying Onion Juice?
No, it is not recommended to wash your hair with plain water, as it won’t remove the odour from your hair. Using a shampoo to clean your hair post-application of onion juice is important. Some may require double shampooing, so it is better to use shampoo as needed.
Q4 - What Are the Disadvantages of Onion Juice on Hair?
People with sensitive scalps may experience scalp irritation, a burning sensation and even dryness sometimes. Overusing the onion juice may aggravate conditions like eczema and also weaken the hair follicles, so it is necessary to be mindful while using the onion juice on hair. Always use it in moderation and do a patch test.
Q5 - Can You Spray Onion Water on Your Hair Every Day?
It is not advisable to spray onion water on hair every day. The high sulfur content can strip off the scalp’s natural oil and moisture, causing irritation, itching or dryness.
Q6 - How to Apply Onion Juice on the Hair Scalp?
Apply it using fingertips or dip a cotton ball in the onion juice and apply it on the scalp directly. Avoid applying it to scratches or minor bumps to avoid irritation.
Q7 - Can We Apply Onion Juice After Oiling?
Ideally, onion juice should be applied to a clean scalp. Applying it to an oily scalp won’t prevent the scalp from absorbing nutrients. To get optimal results, people should avoid using it after oiling unless advised by a doctor.
Q8 - What Happens if You Don't Wash Your Hair After Applying Onion Juice?
If the hair is not washed after applying onion juice, it leaves a strong, pungent odour that is unbearable for someone who can’t tolerate strong smells. It traps dirt, sweat, and residue, which can clog follicles, resulting in itching, irritation, dryness, rashes, or inflammation.
Q9 - Will Onion Juice Regrow Lost Hair?
Onion juice is scientifically proven to work for alopecia areata. However, it is not beneficial to regrow hair in hormonal, genetic, or other pattern hair loss (androgenetic alopecia).
Q10 - How Many Days Can We Store Onion Juice for Hair?
If stored in a refrigerator, it can last for 3 to 5 days. However, using fresh onion juice every time is better to get maximum benefits.
