Homemade Onion Oil for Hair Growth (and Less Hair Fall)
Onion oil is a simple, natural hair care remedy that can help stimulate hair growth, strengthen the roots, and reduce noticeable shedding. With consistent use, many people find their hair looks fuller, healthier, and more resilient.
Key Benefits of Onion Oil for Hair
- Supports faster hair growth by nourishing the scalp

Ingredients
- 1 large red/purple onion (naturally rich in sulfur compounds and antioxidants)

- Optional: 5 drops essential oil (rosemary, lavender, or peppermint to improve the scent and enhance the scalp-care effect)
Step-by-Step Preparation
- Peel and grate the onion, or chop it very finely.
Tip: You can blend it with a small splash of water to speed things up. - Place a pan on low heat, add the coconut oil, then mix in the grated/blended onion.
- Warm gently for 5–10 minutes, stirring occasionally, until the onion releases its juice and the oil turns golden.
- Turn off the heat and let the mixture cool completely.
- Strain the oil to remove onion pulp, then pour it into a clean glass jar with a tight lid.
