Benefits Of Onion Juice For Hair Growth

Using onion juice is a sure-shot method to boosting hair growth and promoting hair regrowth.

The benefits of onion juice for hair growth have been widely praised, with many people sharing noticeable before and after results. Here are some possible reasons behind what makes this ingredient so effective:

  • Onion juice helps improve hair growth by boosting the level of an antioxidant enzymei  Proteins that work as biological catalysts and help speed up chemical reactions. Essential for digestion, liver function, etc. catalase. This enzyme helps decompose hydrogen peroxide, optimizing the hair growth cycle.
  • Sulfur is essential for the regeneration of hair follicles (1). You can add sulfur in your hair care routine with onion juice. It helps nourish your hair follicles with its rich content of sulfur.
  • The rich sulfur content also helps minimize hair thinning and breakage.
  • The antioxidants help reverse premature graying and delay graying.
  • Onion’s rich antibacterial properties help keep your scalp healthy and free of infection, promoting unhindered hair growth. These same properties help control dandruff. So, next time you are facing similar issues, consider using onion juice for dandruff and scalp infection and to boost scalp health.
  • Onion juice stimulates your scalp and improves the circulation of blood, resulting in follicles that are well-nourished.

Doro Cubillo, a YouTuber, embarked on a one-week experiment of applying onion juice on her hair and recorded her experience in one of her vlogs: “If you thought that the egg hair mask was smelly, let me tell you something, you haven’t put onions on your hair.” The adverse smell did not deter her from using it, and she noted a decrease in hair loss as a result of the onion juice treatment (i).

However, onion juice may not work for all. Tanya Wilson, a blogger, shared her experience after using onion juice in her hair care routine: “This may help on occasional use, but long term use, I have not found it to be beneficial (ii).”
