Onion oil has become a popular natural remedy for people looking to improve hair growth and reduce hair fall. Rich in sulfur, antioxidants, and antibacterial compounds, onions may help nourish hair follicles and support a healthier scalp environment. While results vary from person to person, many people use onion-based treatments as part of their hair care routine.
Here’s how to prepare onion hair oil safely and effectively at home.
Why Onion May Help Hair Growth
Onions contain sulfur, which is an important component of keratin — the protein that makes up your hair. Sulfur may help:
-
Strengthen hair strands
-
Reduce breakage
-
Support collagen production
-
Improve scalp circulation
Onions also have antimicrobial properties that may help reduce scalp infections that contribute to hair thinning.
Keep in mind: onion oil is not a guaranteed cure for hair loss, especially if hair fall is caused by hormonal imbalance, genetics, or medical conditions.
Ingredients You’ll Need
-
1–2 medium onions
-
1 cup coconut oil (or olive oil)
-
Optional: a few drops of rosemary oil
Step-by-Step Method
1. Prepare the Onion
Peel and grate or blend the onions into a pulp. Extract the juice using a fine cloth or strainer.
2. Heat the Oil
In a pan, gently heat the coconut oil on low flame. Do not overheat — warm oil is enough.
3. Add Onion Juice
Pour the extracted onion juice into the warm oil and let it simmer on very low heat for 5–10 minutes.
4. Cool and Strain
Allow the mixture to cool completely. Strain to remove any solid particles.
5. Store Properly
Transfer the oil into a clean glass bottle and store it in a cool, dry place. It can last about 1–2 weeks.
