3. Fights Scalp Infections and Dandruff
Thanks to its antibacterial and antifungal properties, onion oil is excellent for maintaining a healthy scalp. It fights dandruff, itchiness, and scalp infections, creating an ideal environment for hair to thrive.

4. Delays Premature Graying
Gray hair before its time? Onion oil might help. It contains catalase, an enzyme that helps break down hydrogen peroxide buildup in hair follicles, which is often responsible for premature graying.
Regular application can help maintain your natural hair color for longer.
5. Improves Blood Circulation for Healthier Hair
Massaging onion oil into the scalp enhances blood circulation, ensuring that hair follicles receive more oxygen and nutrients. This improves overall hair health, making it shinier, thicker, and more resilient.
