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, it 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.
A 2002 study attempted to put onion juice’s hair loss science in action. The group who washed their hair with this 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 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.
How do you use onion juice for hair?
Many people have developed simple instructional home treatments to apply this juice to their hair.
Some people may avoid using onion juice for their hair due to its strong smell. For this reason, some have suggested simple recipes to help curb the onion smell.
What should I know before using onion juice?
Using this juice for hair is mostly safe. If you have an allergy to onions, you shouldn’t use this juice on your hair.
Even among those who are not allergic, onions can be quite caustic to the skin. Side effects may include redness and itching, depending on how potent a concoction you make. Mixing onion juice with an emollient like aloe vera or coconut oil may prevent this.
Don’t use this juice as a cure for alopecia or other hair loss issues. For some conditions — such as alopecia — the only successful cure is a hair transplant.
