Why Onions Are Perfect for Hair Growth

The following are reasons that will explain to you why onion juice is the perfect remedy for hair growth.

It contains dietary sulfur

Onion juice contains sulfur, which is a common mineral in the body that is essential for ample generation of proteins and enzymes. The mineral can also be found in keratin, which is a constituent of hair.

The sulfur contained in onion juice nourishes the scalp and hair with the minerals it requires to grow.

It has anti-microbial properties

Sometimes, hair loss is as a result of bacterial infections. Onions have anti-bacterial properties that help in combating scalp infections.

Obviously, a healthy scalp has strong hair follicles that promote the growth of healthy hair.

Onions have Antioxidants

Onions are rich in antioxidants, which are known to safeguard the body from free radicals. These radicals accelerate the aging process and are believed to destroy hair follicles, which may lead to hair thinning and hair loss.

Onion juice works to reduce these free radicals in the body hence minimizing damage to hair follicles and promoting hair growth.

It Improves Blood Circulation

When applied to the scalp and massaged, onion juice gets the scalp stimulated and enhances blood circulation.

This nourishes the hair follicles and signals the brain to release androgens, which are the hormones responsible for hair growth.

How to Remove Onion Smell from Hair after Applying

While onion works well to increase hair growth, it still has an unpleasant smell that will not go away after washing your hair with shampoo and water.

Here are several ways to completely get rid of the onion smell from your hair.

Using Lemon Juice

Lemon is good at getting rid of smells. You want to squeeze a couple of lemons to get a cup of juice then apply to wet hair.

Allow the juice to sit in your hair for about twenty minutes and rinse off with water. You want to avoid exposure to sunlight when having this solution on as it can lighten your hair.

Using Baking Soda

Baking soda is known for neutralizing smells. It therefore does not come as a surprise that it can be used to get rid of the onion smell from your hair.

Just add one or two tablespoons to your shampoo and wash normally.

Using Mint and Rosemary

When combined, rosemary and mint can strip your hair of any strong smell. All you have to do is boil the two for about five minutes.

Once the solution is cool, apply it to wet hair and let it sit for about fifteen minutes and then rinse with water.


If you did not know that onion juice could restore your hair’s health, you can now see the benefits. What we love most is that onion is a natural remedy that is less likely to cause side effects.
