Onion Juice for Hair Loss: Does it really work?

Hair loss is a common concern for both men and women, often leading individuals to seek out various remedies and treatments in their quest for a fuller head of hair. One such remedy that has gained popularity in recent years is the use of onion juice. However, as with many home remedies, the efficacy of onion juice for hair loss remains a topic of debate among experts.

To answer this, Lordhair – a leading men’s hairpieces and women wigs supplier globally – decided to delve into the existing research and explore the potential mechanisms behind onion juice’s purported benefits for hair loss. Read on!

Onion for hair loss

Onions are known to be rich in sulfur, a mineral that plays a vital role in the production of keratin, the protein that constitutes the structure of hair. Sulfur is essential for maintaining healthy hair follicles and promoting hair growth. Additionally, onions are believed to possess antimicrobial properties, which may help combat scalp infections that can contribute to hair loss.

Study on onion juice for hair loss

Several studies have explored the potential benefits of onion juice for hair loss. A study published in the Journal of Dermatology investigated the effects of onion juice on patients with alopecia areata (an autoimmune condition that causes hair loss). The results showed that applying onion juice twice daily for two months led to significantly higher hair regrowth rates compared to a control group using tap water.

While this study showed promising results, it is crucial to note that they were conducted on small sample sizes and focused on specific types of hair loss. As such, more extensive, controlled clinical trials are needed to establish onion juice’s efficacy for various types of hair loss, such as androgenetic alopecia (male or female pattern baldness), which is the most common form of hair loss.

While onion juice may have potential benefits for hair health, it is essential to approach it as a complementary treatment rather than a standalone solution. Maintaining a balanced diet rich in nutrients essential for hair growth, such as proteins, vitamins and minerals is crucial. Additionally, a healthy lifestyle, stress management and avoiding harmful hair care practices can contribute to overall hair health. 


Onion juice has shown promise in promoting hair growth and reducing hair loss in some studies. However, more research is needed to establish its effectiveness across various types of hair loss. Individuals interested in using onion juice for hair loss should consult with a healthcare professional or a dermatologist to ensure they are addressing their specific hair loss concerns effectively and safely.
