Why Onion Oil Works for Hair Growth
Modern research supports what traditional remedies have known for generations — onions are a powerhouse for hair health.
Key benefits backed by science:
- Stimulates Hair Follicles:
Onions are rich in sulfur, a mineral vital for the production of keratin (the protein that makes up hair). This improves blood circulation to the scalp, awakening dormant follicles. - Prevents Hair Breakage:
Sulfur strengthens hair strands, reducing split ends and brittleness. - Fights Scalp Infections:
Onion’s antibacterial and antifungal properties protect the scalp from dandruff and other conditions that hinder hair growth. - Delays Premature Greying:
Onions contain antioxidants like catalase that help maintain natural hair color. - Improves Overall Hair Health:
Regular application leads to shinier, thicker, and more voluminous hair.
📊 Did you know? A 2014 study published in the Journal of Dermatology showed that 87% of participants experienced noticeable hair regrowth within 6 weeks of using onion juice twice a day.

Ingredients:
- 2 large red onions (rich in sulfur and antioxidants)

Equipment Needed:

Step-by-Step Method:

Using cheesecloth, squeeze out the juice from the onion paste into a bowl. - Heat the Base Oil:
In a pan, heat coconut oil on low flame. Add the extracted onion juice gradually, stirring continuously. - Infuse and Simmer:
Allow the mixture to simmer on low heat for 10–15 minutes until the raw smell fades and the oil turns light golden. - Add Castor Oil and Rosemary Oil:
Stir in castor oil and essential oil after turning off the heat. - Cool and Store:
Let the mixture cool completely before transferring it into a glass jar. Store in a cool, dry place.
