Onion juice is a known remedy for hair health, specifically for hair loss. It’s been used for decades as a home treatment. 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. 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. Using onion juice for hair is mostly safe. If you have an allergy to onions, you shouldn’t use onion juice on your hair.
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.
