Are you having a tough time with slow hair growth or too much hair fall? Onion juice might just be the natural remedy you’re looking for! Rich in sulfur, antioxidants, and antibacterial properties, onion juice can strengthen the hair follicles while accelerating the growth and fighting any infection on the scalp.
In this article, we’ll show you how to prepare a very easy DIY onion juice treatment for thicker, longer, and healthier hair.
Benefits of Onion Juice for Hair Growth
- Stimulates Hair Follicles – Sulfur in onions enhances collagen production, thus stimulating fresh hair growth.
- Reduces Hair Fall – The antibacterial property helps in keeping the scalp healthy, thus reducing breakage.
- Fights Dandruff & Scalp Infection- The antifungal properties of onion juice can prevent flakiness and itching.
- Improves Blood Circulation- Massaging the scalp with onion juice boosts nutrient delivery to the hair roots.

How To Prepare Onion Juice For Hair Growth
Ingredients:
- 1 medium-sized onion, either red or white
- A blender or grater
- A strainer or cheesecloth
- Optional: 1 tsp honey or aloe vera gel (to help mask the strong scent)
Method:
- Extract the Juice: Peel and fine chop the onion, and either blend or grate the onion. Strain the pulp through some cheesecloth or a similar cloth to extract the juice.
- Optional Add-Ins – You can add honey or aloe vera to moisturize the hair and minimize the odour.
- Application –
- Part hair and apply the juice directly onto the scalp using a cotton ball or dropper.
- Gently massage using your finger for 5-10 minutes to allow proper absorption.
- Leave on for 30-45 minutes (or overnight for better results).
4. Rinse Well: Remove the odour with a mild shampoo.
Frequency:
Apply just 2-3 times a week for the best results. Hair fall should decrease in a few weeks, and hair growth should be possible within one to two months.
Pro Tips For Best Results
- Patch Test Before Applying On The Hair– To check for allergies, please apply a small amount to your skin.
