The tell-tale signs of aging can be difficult to accept. One of the more common indications of getting older is when your hair starts to gray. While some people embrace their new look, others scramble to find ways to cover up the gray.
Among others, using onion juice for gray hair has become a popular method. You may have heard of it from a friend or someone else, but the question remains – does it work?
Onion Juice for Gray Hair: The Effectiveness
If you are looking for an all-natural way to help slow down the progression of gray hair, then onion juice may be a good choice for you. It is affordable, easy to find, and comes with a variety of other benefits for your hair health. However, it is important to note that more research is needed to assess its full effectiveness as a treatment for gray hair.
Onion Juice for Gray Hair: The Science
The science behind using onion juice for gray hair is that the sulfur in onions helps to produce melanin, which is responsible for giving your hair its color. When onion is applied to the scalp, the hair follicles absorb the sulfur, and thus melanin is produced. Up to this writing, there has not been any scientific study conducted on humans that proves onion juice can reverse hair graying.
Instead, it can help slow down or stop the progression of gray hair in some people. The superfood’s potent chemical ingredient called quercetin can actually help protect against hydrogen peroxide buildup and thus restore some of its natural colors by creating a barrier that prevents further destruction from this element. Furthermore – in addition to preventing gray hairs – it also has been proven able to increase shine as well as strength for healthier strands!
While it may not completely turn your gray hair and restore its original color, onion also comes with a multitude of benefits for your hair. A study in 2018 has shown that onion juice can improve the quality of hair and scalp health. It helps promote hair growth, can prevent hair loss, and can also help stimulate your scalp.
The study found that onion juice has anti-inflammatory, antimicrobial, and antioxidant properties,. which all work together to improve scalp health.
Other benefits of onion on your hair may include but are not limited to:
- Protection from the sun’s UV rays
- Prevention of split ends
- Reduced dandruff
- Hair growth
How to Use Onion Juice for Gray Hair
For this process to work, you will need:
- One onion, preferably red
- A juicer or blender
1. Peel the onion and cut it into small pieces.
Have a box of tissues on standby!
2. Juice it with a juicer or blender.
If you are using a juicer, the juice will be collected in one container and separated from any pulp or sediment that may have come into contact with it during the process. If you are blending, then the blended onion will contain the juice and pulp.
3. Strain the mixture to get just the juice (optional).
Blended onion will need to be strained and separated to get the juice unless you don’t mind the bits of onion pieces in your hair. Or, you can strain it through a cheesecloth or fine metal mesh sieve to remove any large pieces.
4. Dilute with water.
After you have strained the onion juice, then mix it with an equal amount of water before applying it to your scalp as above.
5. Apply to the scalp.
Apply the diluted juice directly to your scalp and massage it well. Leave it on for 30 minutes before rinsing off with your favorite shampoo and conditioner for gray hair.
6. Repeat as needed

Take care to avoid touching your eyes when handling onions. The juice can cause irritation if it comes into contact with your eyes.
Wear gloves when juicing or blending the onion to avoid any skin irritation.
If you do get some of the juice in your eye, rinse it out immediately with cold water.
Another thing to consider if you are using onion juice for gray hair is that it may cause your scalp or skin to be more sensitive to the sun. This means that you should wear sunscreen, protective clothing, and hats when spending time outdoors in order to lower your risk of developing skin cancers.
If you are using onion juice for gray hair, then it is recommended that you use either red or yellow onions. White onions will not work as well as it contains fewer quercetin molecules.

You can do a patch test to check for any allergic reaction before applying the onion juice. Apply a little bit of it on your inner arm and wait 24 hours to see if you develop any signs of irritation, such as redness, itching, or swelling.
You can also test for any allergic reaction by applying a small amount of the juice behind your earlobe where there is less skin sensitivity.
On very rare occasions, you may experience anaphylaxis, a serious allergic reaction that occurs when your immune system overreacts to the allergen. Symptoms of this can include difficulty breathing, hives or welts on your skin, dizziness, and/or fainting. After using onion juice, seek medical attention immediately if you have these symptoms.
