Onion Hair Oil has become one of the most talked-about hair care solutions in recent years, especially for those suffering from hair fall, thinning hair, and weak roots. After hearing countless reviews and seeing high ratings online, I decided to put two of the most popular onion-based oils to the test: Mamaearth Onion Hair Oil and WOW Skin Science Onion Black Seed Hair Oil. I used each oil for over a month to genuinely observe how they performed on my scalp and hair. Here is my honest user review, detailing everything from packaging and application to performance and final results.

Understanding Hair Fall and the Promise of Onion Hair Oil
Hair fall can be caused by several factors, including stress, poor diet, pollution, hormonal imbalance, and the use of chemical-based products. Onion Hair Oil promises to combat hair fall naturally. Rich in sulfur, antioxidants, and antibacterial properties, onion oil is believed to strengthen hair follicles, reduce breakage, and promote new hair growth. But not all onion hair oils are created equal – and that’s exactly what I wanted to explore.

Packaging and Application: My Experience
Mamaearth comes in a pump bottle, which is hygienic and user-friendly. I liked that it dispensed just the right amount of oil. WOW, on the other hand, scores points with its comb applicator that lets you directly apply the oil to your scalp with zero mess. Both bottles are travel-friendly and well-designed.
My Verdict: WOW wins in terms of smart packaging, but Mamaearth’s pump also does a decent job.
Texture and Fragrance
Mamaearth Onion Hair Oil is slightly thick but still spreads easily. It has a mild herbal scent, which disappears after a few hours. WOW Onion Hair Oil is lighter and has a stronger, more herbal fragrance due to black seed oil. Some may find WOW’s smell overpowering, especially if you’re sensitive to strong scents.
My Verdict: Mamaearth scores higher for subtle fragrance, while WOW is better for lightweight feel.
Performance and Results
I used each oil for 4 weeks, twice a week, followed by a mild shampoo. With Mamaearth, I noticed reduced hair fall by the end of the second week. My hair felt thicker, and there was a visible difference in hair breakage. WOW also gave good results but took longer to show visible changes. However, it made my hair shinier and smoother.
My Verdict: Mamaearth performed slightly better in reducing hair fall, while WOW is great for shine and hair texture.
Suitability and Hair Types
Both oils worked well on my medium-length, slightly dry hair. I believe Mamaearth is more suitable for people with excessive hair fall and brittle strands. WOW, on the other hand, suits people looking for a nourishing, all-in-one oil that improves overall hair health.
My Verdict: Choose Mamaearth if hair fall is your primary concern. Pick WOW if you want a shine-boosting, strengthening oil.
Tips to Maximize Results from Both Onion Hair Oils
- Apply on Clean Scalp:
Always use on a clean, dry scalp to allow better absorption of nutrients. - Warm the Oil Slightly:
Lukewarm oil penetrates deeper into the scalp and improves circulation, enhancing effectiveness. - Massage Gently:
Use your fingertips to massage the oil in circular motions for at least 5–10 minutes. This boosts blood flow and strengthens hair roots. - Leave Overnight:
Leaving the oil overnight (or at least 2–3 hours) allows ingredients like onion extract and black seed oil to work deeply. - Use 2–3 Times a Week:
Regular and consistent use delivers better results than occasional application. - Follow with a Mild Shampoo:
Use a gentle, sulfate-free shampoo to avoid stripping the natural oils. - Stay Hydrated & Eat Balanced Diet:
Healthy hair begins from within. A good diet supports better oil performance. - Track Your Progress:
Take photos every 2–3 weeks to monitor hair fall reduction and new hair growth.

My Final Verdict
Both Onion Hair Oil products have their strengths. If you’re looking for a solution that primarily targets hair fall and promotes growth, Mamaearth Onion Hair Oil is slightly more effective based on my experience. If you’re more concerned with shine, nourishment, and ease of application, WOW Skin Science is a great pick.
For best results, consistency is key. Whichever oil you choose, stick to a regular routine, pair it with a mild shampoo, and maintain a healthy diet to support hair growth from the inside out.
