If you’re struggling with hair loss and looking for an affordable, natural way to support your scalp, onion juice might be worth a try. This kitchen staple is gaining attention as a natural remedy for hair loss and growth, offering a low hair regrowth cost compared to salon hair regrowth treatments or prescription products. Rich in sulfur and antioxidants, onion juice can help boost hair follicle growth, strengthen existing strands, and even encourage real hair regrowth when used consistently.
- Almost half of adults will experience some form of hair thinning before 50.
- Many commercial hair treatment for hair loss options can be expensive and inconsistent in results.
- A DIY approach like onion juice can be a cost-effective way to promote scalp regrowth at home.
1. Sulfur Supercharge for Stronger Hair
Sulfur is essential for producing keratin—the protein that makes up your hair. By giving your hair a sulfur boost, you can improve strand strength, potentially reducing hair fall and hair regrowth cycles caused by breakage.
2. Improves Blood Circulation
Applying onion juice to your scalp stimulates blood flow to the follicles. Better circulation means healthier roots, which can help prevent a decrease in hair growth and encourage new hairs to sprout.
3. Antioxidant Power to Calm the Scalp
Onion juice contains quercetin, a powerful antioxidant that can soothe irritated or inflamed skin. A calmer scalp is better prepared for hair regrowth treatments and can reduce shedding linked to minor inflammation.
4. Fights Scalp Issues Naturally
Its antibacterial and antifungal properties can help keep the scalp clean, fight dandruff, and unclog follicles—removing barriers that might slow hair regrowth.
💡 Research-backed tip: In one clinical study, nearly 90% of participants who applied onion juice twice daily for two months saw noticeable new growth—compared to just 13% in the placebo group.
How to Make Onion Juice for Hair at Home
You’ll need:
- 2–3 onions (any variety—red, yellow, or white)
Steps:
- Peel and chop the onions.
- Blend or finely grate them.
- Strain the mixture with a cheesecloth or fine mesh sieve.
- Optional: Mix with coconut oil, aloe vera gel, or rose water to soften the smell and reduce irritation.
How Often to Use
Applying it 2–3 times per week can help balance hair fall and hair regrowth phases over time.
How to Apply
- Start with a clean, dry scalp.
- Use a cotton ball or fingertips to apply the juice to your scalp.
- Massage gently for 2–3 minutes to boost hair follicle growth through increased absorption.
- Leave on for 30–60 minutes.
- Rinse thoroughly with a mild shampoo.
Timeline of Results
- 4–6 weeks: Less shedding and healthier scalp condition.
- 8–12 weeks: Early signs of real hair regrowth, like fine baby hairs along the hairline.

Staying Safe and Avoiding Irritation
- Always patch test before full application.
- Don’t apply to broken or highly sensitive skin.
- Avoid daily use and mixing too many strong treatments at once.
