Does onion juice for hair loss work?
Science shows that there are many ways onion juice can help with hair loss. For one, onions are high in dietary sulfur, a nutritional element our bodies need.
Sulfur is found within amino acids, which are components of protein. Proteins — and especially keratin, which is known to be sulfur-rich — are needed for growing strong hair.
When added to the hair and scalp, onion juice can provide extra sulfur to support strong and thick hair, thus preventing hair loss and promoting hair growth.
The sulfur from onions may also help promote collagen production. Collagen in turn helps the production of healthy skin cells and hair growth.
It’s also believed that onions may boost circulation. Applying onion juice to the hair and scalp could increase blood supply to hair follicles, which in turn improves hair growth.
There have been studies on how onion juice prevents hair loss, but not on its other benefits.
A 2002 study attempted to put onion juice’s hair loss science in action. The group who washed their hair with onion juice experienced more hair growth than those who washed it with tap water. Men also appeared to experience a greater benefit than women.
However, the study is over a decade old, and not all subjects completed the test. More research is needed into how onion juice works and if its benefits are significant. Nevertheless, many more recent studies and reviews of natural hair loss treatments reference the study as reliable evidence that onion juice can be helpful.
On the other hand, onion juice shouldn’t be considered a cure for hair loss conditions like alopecia or pattern baldness. It can help stimulate and protect growth of current hair, but it’s not known to reverse any hair loss-related illness.

The bottom line
Onion is a safe, natural, and affordable home remedy that can be great for your hair. Many people have reported that it improves thickness, stimulates growth, and even regenerates new growth when dealing with hair loss.
Still, onion juice is not a cure for pattern baldness, alopecia, or other hair loss-related disorders.
