Does Onion Promote Hair Growth?


Does onion promote hair growth?


Onion is a common vegetable that has many benefits for your health and beauty. In this blog, I will tell you how onion can help you grow your hair faster and stronger, and how to use it in different ways.

Onion contains a lot of sulfur, which is a mineral that is essential for the production of keratin, the protein that makes up your hair. Sulfur also improves blood circulation to the scalp, which stimulates the hair follicles and promotes hair growth. Onion also has anti-inflammatory and antimicrobial properties, which can help prevent scalp infections and reduce hair loss.



There are many ways to use onion for hair growth, but the most popular one is to apply onion juice to your scalp and hair. Here are some steps to follow:

  • Peel and chop one or more onions, depending on the length and thickness of your hair.
  • Blend the onion pieces in a blender or a food processor until you get a smooth paste.
  • Strain the paste through a cheesecloth or a fine sieve to extract the juice.
  • Apply the juice to your scalp and hair, making sure to cover all the areas where you want to see hair growth.
  • Massage your scalp gently for a few minutes to enhance absorption.
  • Leave the juice on your hair for at least 15 minutes, or up to an hour if you can tolerate the smell.
  • Rinse your hair with water and shampoo as usual.



You can repeat this process two or three times a week for best results. You can also add some lemon juice, honey, or essential oils to the onion juice to mask the smell and add some extra benefits. For example, lemon juice can help lighten your hair color, honey can moisturize your hair, and essential oils can add fragrance and nourishment.

Another way to use onion for hair growth is to make an onion hair mask. This involves mixing onion juice with other ingredients that are good for your hair, such as eggs, yogurt, olive oil, coconut oil, or aloe vera gel. You can apply this mixture to your hair and leave it on for 20 to 30 minutes before washing it off. This will help condition your hair and make it softer and shinier.


Some people also use onion oil for hair growth. Onion oil is made by infusing chopped onions in a carrier oil, such as coconut oil or olive oil, for several days or weeks. You can then strain the oil and use it to massage your scalp and hair regularly. Onion oil can help nourish your hair and prevent breakage and split ends.

Onion is a natural and inexpensive way to boost your hair growth and improve your hair quality. However, there are some possible side effects that you should be aware of before using it. Some of these are:

  • Allergic reaction: If you are allergic to onions, you should avoid using onion on your hair. You may experience itching, redness, swelling, or rash on your scalp or skin.
  • Eye irritation: Onion juice can cause tears and burning sensation in your eyes if it comes in contact with them. You should be careful not to let the juice drip into your eyes while applying it. You can also wear goggles or glasses to protect your eyes.
  • Dryness: Onion juice can dry out your scalp and hair if used too often or in large amounts. You should always moisturize your hair after using onion juice with a conditioner or a natural oil.
  • Smell: Onion juice has a strong and unpleasant smell that may linger on your hair even after washing it. You can try to mask the smell by adding some lemon juice, rose water, or essential oils to the onion juice. You can also rinse your hair with apple cider vinegar or baking soda after shampooing it.


Onion is a wonderful ingredient that can help you achieve healthy and beautiful hair. You can use it in various ways to stimulate hair growth and prevent hair loss. However, you should also be careful about the possible side effects and precautions when using onion on your hair. If you have any doubts or questions about using onion for hair growth, you can consult a doctor or a hairstylist before trying it.
