Study: How effective is onion juice for hair growth?

onion juice for hair regrowthA research study published by the Journal of Dermatology shows that onion juice can be an effective remedy for treating alopecia.

For this specific study, all participants had alopecia areata (also known as patchy hair loss caused by auto-immune disease) and the goal was to find out the effectiveness of onion juice as a topical hair loss treatment.

How was the study designed?

The participants were then divided into 2 groups

  • Group 1: Treated with onion juice topically
  • Group 2: Treated with tap water topically (Control / Placebo group)

The first group of participants were advised to apply crude onion juice to their scalp twice a day, while the other group (tap water treated) was served as the placebo group.

The study results:

  • 2 weeks: The study shows after 2 weeks of applying crude onion juice twice everyday, the research team started noticing new hair growth in some patients.
  • 4 weeks: 74% of participants (17 people) experiencing re-growth
  • 6 weeks: The researchers observed 87% of participants (20 people) with hair regrowth. They also found that men show the better response than women (Hair re-growth observed in 93.7% male and 71.4% female).


The positive result from the study indicates that using onion juice as a topical hair loss natural treatment can be an effective solution for people suffering from alopecia areata.

Note: While the study was designed for treating alopecia areata participants naturally, many people also use onion juice for androgenetic alopecia (the most common hair loss for male and female – also known as pattern hair loss).
