Why Onion Oil is a Game-Changer for Hair Health | Benefits Explained
Onion oil is extracted from onions (Allium cepa) and is rich in sulfur, which is essential for keratin production—the protein that makes up hair. Here’s why it’s a must-try:
1. Promotes Hair Growth
Sulfur improves blood circulation to hair follicles, stimulating growth and reducing thinning.
2. Reduces Hair Fall
Antioxidants in onion oil strengthen hair roots, preventing breakage and excessive shedding.
3. Fights Dandruff and Scalp Infections
Its antibacterial and antifungal properties keep the scalp healthy, reducing flakiness and itchiness.
4. Adds Shine and Softness
The natural nutrients in onion oil condition hair, making it smoother and more lustrous.
5. Prevents Premature Greying
Catalase enzyme in onions reduces hydrogen peroxide buildup, delaying greying.
