Benefits Of Onion Juice For Hair Growth

Using onion juice is a sure-shot method to boosting hair growth and promoting hair regrowth. Onion juice for hair growth has received great reviews online from users with 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 enzyme catalase. This enzyme helps decompose hydrogen peroxide, optimizing the hair growth cycle.
  • It helps nourish your hair follicles with its rich content of sulfur. Sulfur is essential for the regeneration of your hair follicles (1).
  • 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 also help control dandruff.
  • Onion juice stimulates your scalp and improves the circulation of blood, resulting in follicles that are well-nourished.
