Onion hair oil has been used for generations as a natural remedy to stimulate hair growth, reduce thinning, and strengthen the scalp. Onions are packed with sulfur, antioxidants, and essential nutrients that improve blood circulation and nourish hair follicles. When combined with carrier oils, this potent ingredient helps reduce hair fall, prevents premature graying, and promotes thicker, shinier strands. Unlike commercial products filled with harsh chemicals, onion hair oil is cost-effective, safe, and easy to prepare at home. With consistent use, it can bring noticeable improvement in scalp health and hair density.
Ingredients
- 2 medium-sized red onions, peeled and chopped
- 1/2 cup coconut oil (or olive oil as an alternative)
- 1/4 cup castor oil for added thickness
- 8–10 curry leaves (optional, for strengthening hair roots)
- 4–5 drops rosemary essential oil (optional, for fragrance and growth stimulation)
Instructions
- Blend or grind the chopped onions into a fine paste. Strain the paste using a muslin cloth or sieve to extract the juice.
- In a pan, heat coconut oil and castor oil on low flame. Add the onion juice and curry leaves. Simmer for 7–10 minutes until the mixture gives off a mild aroma. Turn off the flame and let it cool.
- Strain the oil into a clean glass jar or bottle. Add rosemary essential oil if desired. Massage this oil into your scalp for 15–20 minutes before leaving it on for at least 1–2 hours or overnight. Wash off with a mild shampoo.

Notes
Always perform a patch test before using onion hair oil to check for allergies or scalp sensitivity. Store the oil in a cool, dry place in an airtight container. Use within 3–4 weeks for maximum potency. A mild onion smell may linger even after washing, so adding essential oils helps mask the odor.
Tips
For best results, apply onion hair oil 2–3 times a week. Do not heat the oil on high flame as it may burn and lose nutrients. Pair regular oiling with a balanced diet rich in protein, vitamins, and minerals to maximize hair growth naturally. Rinse hair with a mild, sulfate-free shampoo to avoid dryness.
Health Benefits
Onion hair oil improves blood circulation in the scalp, delivering more oxygen and nutrients to hair follicles. The sulfur in onions supports keratin production, which strengthens hair strands and reduces breakage. Antioxidants fight free radicals that cause premature graying, while castor oil boosts thickness and coconut oil deeply moisturizes. Curry leaves provide vitamins and minerals that reinforce roots, while rosemary essential oil further stimulates hair growth. Regular application reduces dandruff, soothes itchy scalp, and promotes healthier, shinier, and denser hair.
