From a nutritional standpoint, onion juice is high in sulphur, a substance that is thought to stop hair loss and breaking. It helps in improving hair growth and blood circulation and also provides antioxidant and antimicrobial properties.

However, it also has downsides and can do the opposite causing hair loss. The simplicity of application makes any homemade cure with a widely available component popular and onion juice can definitely benefit you but can also do some damage.

This hack might not be useful to everyone. It could cause more damage than benefit. If compared to other people, it can respond differently for some.

What does Science say about Onion juice and oil?

Although not extensively researched a small study showed that applying onion juice to the scalp twice a day might help hair regrow in some people. Almost 74% of participants had some hair regrowth after 4 weeks, and at 6 weeks about 87% experienced hair regrowth. The participants had alopecia areata, a patchy non-scarring type of hair loss.

Even onion juice alone sometimes causes skin irritation. People with allergies may have symptoms after coming into contact with onion juice on their skin. To determine if you are allergic, use a patch test. If you have hair loss, consult with your dermatologist or trichologist. Do not use home remedies without first contacting a professional.
