How Onion Helps in Hair Growth?

Onion is rich in sulfur. This mineral is one of the main building blocks of hair. It improves blood circulation and provides the hair follicles with sufficient nourishment. Onion also has anti-bacterial properties, so it helps with scalp infections that might contribute to hair loss.

Furthermore, it contains the enzyme catalase, which is an anti-oxidant that can prevent premature graying for some people (I also wrote an article about the top natural supplements for treating premature gray hair).

Onion for Hair Growth – The Research

Onion’s potential as a potent home remedy for hair loss has also been studied scientifically. In 2002, the Journal of Dermatology published a small study that looked into the use of onion juice for alopecia areata (an autoimmune disease that presents with patchy hair loss).

Participants who applied onion juice twice daily for two months experienced much better hair re-growth rates compared to those who only used tap water. In the study, hair regrowth was observed in 87% of patients treated with onion juice. Men had better success with the treatment than did women.

Onion Juice for Hair Growth – Frequently Asked Questions

How much time does it take to see results?

It takes a while before noticing results – as much as four to six weeks. According to the research about onion juice for hair growth, at four weeks, hair re-growth was seen in 74% of the participants and, at six weeks, the hair re-growth was observed in 87% of the participants.

Does the onion juice treatment really work?

According to the research, 87% of the participants had hair regrowth by using the onion juice twice daily on their scalp. Some of the readers of this article also left comments that it worked for them.

Does it matter what type of onion is used for the hair loss treatment?

There are various types of onions, and they are all vary slightly in flavor, texture, and color, but can usually be substituted for one another. I couldn’t find any reference that mentioned specifically a certain type of onion that is better for hair growth than any other type of onion.

After applying the onion juice I am feeling more hair loss – should I stop applying the juice?

I believe you’ve lost hair during massaging the scalp. I don’t believe you’ve lost the hair because of applying the onion juice. Too much massaging, unlike gentle massage, may cause hair loss. Massaging the scalp should boost up the blood circulation and aid hair growth. I can only believe that the hair you lost was about to fall out anyway soon. We also lose normally about 100 strands everyday, sometimes less, sometimes more. Follow the onion juice application with a gentle massage for a few weeks to see if you notice any improvement. If you don’t see any improvement, discontinue with the treatment.
