1. Massage the oil gently into your scalp.

2. Leave it on for at least 30 minutes (or overnight if tolerated).

3. Wash thoroughly with a mild shampoo.

Use 2–3 times per week for best results.

Precautions Before Use

• Always do a patch test to check for irritation.

• Avoid using on a damaged or inflamed scalp.

• If you experience burning or severe itching, stop immediately.

• People with sensitive skin may dilute the oil further.

When to See a Doctor

If hair fall is sudden, severe, or accompanied by other symptoms such as fatigue, weight changes, or hormonal irregularities, consult a healthcare professional. Conditions like thyroid disorders, anemia, or genetic hair loss require proper medical evaluation.

Final Thoughts

Onion hair oil is a simple, affordable home remedy that may support healthier hair when used consistently. While it may not work miracles overnight, combining natural treatments with good nutrition, stress management, and proper hair care can improve overall scalp health.
