Hair fall, thinning, and slow growth, sound familiar? You’re not alone. With stress, pollution, and product build-up wreaking havoc on our scalps, it’s no wonder that more and more people are searching for natural, effective ways to grow thicker, longer hair without shelling out hundreds on salon treatments.

The humble onion isn’t just a flavour booster for your pasta sauce, it’s also one of the most powerful, science-backed natural remedies for hair growth.
Why onion juice works wonders
Onions are rich in sulfur, a vital mineral that promotes collagen production. Collagen, in turn, supports the growth of strong, healthy strands from the follicle up. Sulfur also improves blood circulation to the scalp, meaning better nutrient delivery to your roots.
But that’s not all. Onions also contain antibacterial and antifungal properties that help keep scalp infections, dandruff, and clogged follicles at bay, common culprits behind hair fall.In a 2002 study published in the Journal of Dermatology, participants who used onion juice on their scalp twice a week saw hair regrowth in just 4 weeks, with significantly better results compared to those who didn’t. That’s the kind of clinical backup that makes this home remedy worth a shot.
