What the science says

When we say that onion juice is beneficial for your hair, we are not saying just because. In fact, there are a number of studies that show onion juice can help with your hair health.

As mentioned previously, onions are rich in dietary sulfur, a nutritional element our bodies need. Think of this for a second, proteins, mainly keratin, are needed for strong hair. And keratin is protein-rich.

When added to the scalp and hair, onion juice provides a boost of sulfur that supports strong and thick hair growth. In the same time, onion juice prevents hair loss and hair thinning.

In 2002, a study tried to show how onion juice helps with hair growth. Now, that is an old study, but the results were obvious. The group that washed its hair with onion juice experience more hair growth.
