Introduction
Struggling with thinning hair or bald patches? You’ve probably heard that onion juice can help regrow hair—but is it just another trend or a time-tested natural remedy?
In this post, we’ll break down the science, benefits, and application methods behind using onion juice for hair loss. If you’re looking for a cost-effective, DIY solution, this might just be your next go-to.
Why Onion Juice Is Used for Hair Regrowth
Onions are rich in sulfur, a mineral essential for building strong hair strands and stimulating follicles. They also contain:
- Antioxidants like quercetin, which reduce scalp inflammation.
- Antibacterial properties to fight scalp infections and dandruff.
- Enzymes that improve blood flow to hair roots.
Scientific Backing: What Studies Say
A small study published in the Journal of Dermatology (2002) showed that participants who used onion juice twice daily for two weeks saw significant regrowth compared to those who used plain water.
While larger studies are needed, anecdotal and early clinical evidence supports its potential effectiveness.
