Sulfur, a mineral abundant in onions, is crucial to hair growth. It is a key component in keratin production, a protein that makes up most of our hair, skin, and nails. (ref

Providing the hair follicles with ample sulfur and onion juice helps strengthen the hair shaft and promotes healthy growth. In addition to their sulfur content, onions are rich in antioxidants, such as quercetin and vitamin C. 

These antioxidants help protect hair follicles from damage caused by free radicals, which can contribute to hair loss and thinning.

A study published in the Journal of Dermatology found that participants who applied onion juice to their scalps twice daily experienced significant hair regrowth compared to those who used a placebo. (ref)

After six weeks, 87% of the onion juice group noticed an improvement in hair growth, while only 13% of the placebo group reported any changes.

Researchers believe that onion juice’s success in promoting hair growth can be attributed to its ability to improve blood circulation in the scalp. The increased blood flow delivers essential nutrients and oxygen to the hair follicles, stimulating them to produce new, healthy hair. 

Additionally, onions’ antimicrobial properties help combat scalp infections and conditions like dandruff, which can contribute to hair loss.

You can easily prepare onion juice at home to harness its hair growth benefits. 

  • Blend a few onions in a food processor or juicer, then strain the liquid to extract the juice.
  • Apply the onion juice directly to your scalp, massaging it for several minutes. 
  • Leave the juice on for at least 30 minutes before rinsing it with water and shampooing as usual.
  • For best results, repeat this process two to three times per week. While the smell of onion juice may be strong, you can mix it with a few drops of essential oils, such as peppermint or lavender, to help mask the odor. 

Be sure to perform a patch test before applying onion juice to your entire scalp, as some individuals with sensitive skin may experience irritation.

Embracing onion juice as a hair growth solution provides a natural alternative to harsh chemicals and medications and highlights the importance of looking to nature for answers to common health concerns.
