How to Make Onion Hair Oil for Faster Hair Growth and to Stop Hair Fall

air fall, thinning edges, slow growth, and patchy scalp are problems millions of people face daily. While commercial hair products promise miracles, many rely on harsh chemicals that often worsen the issue over time. One natural remedy that keeps resurfacing in traditional beauty routines is onion hair oil—a simple, affordable, and surprisingly powerful solution.

This guide shows you how to make onion hair oil at home, how it works, how to use it correctly, and why it may help reduce hair fall while promoting faster, healthier growth.

Why Onion Hair Oil Works

Onions are not just a kitchen staple—they’re a nutrient powerhouse for the scalp.

Key Hair-Boosting Compounds in Onion

• Sulfur – Essential for keratin production, the protein that builds hair strands

• Quercetin – A potent antioxidant that reduces scalp inflammation

• Antimicrobial compounds – Help fight dandruff, fungal infections, and clogged follicles

• Vitamins B & C – Support blood circulation and collagen synthesis

When infused into oil, these compounds penetrate the scalp more gently than raw onion juice, making onion oil less irritating but more sustainable for long-term use.

Benefits of Onion Hair Oil

Using onion hair oil consistently may help:

• Reduce excessive hair fall and breakage

• Stimulate dormant hair follicles

• Improve scalp circulation

• Strengthen hair roots

• Add shine and thickness

• Support regrowth in thinning or patchy areas

Many people notice less shedding within 2–3 weeks and visible baby hairs after 4–6 weeks of consistent use.
