Apply to scalp and hair 2–3 times weekly for 4–6 weeks, leaving on for 30–60 minutes or overnight.

Yield
~¾–1 cup of onion oil.
Precautions
Patch test on inner wrist for 24 hours to avoid irritation.
Avoid eyes to prevent stinging.
Use sparingly (2–3 times weekly) to prevent scalp sensitivity.
Consult a dermatologist for sensitive skin or scalp conditions.
Use organic onions and oils to avoid pesticides.
How to Use for Maximum Results
Application: Apply 1–2 tbsp onion oil to clean, dry scalp, massaging gently for 5–7 minutes to boost circulation. Spread to hair ends. Leave for 30–60 minutes or overnight with a shower cap to avoid staining, then wash with a mild, sulfate-free shampoo like Parachute Advansed Onion Hair Oil’s complement. Use 2–3 times weekly for 4–6 weeks.
Lifestyle Pairing: Pair with a diet rich in protein (eggs), iron (spinach), and vitamin C (berries) to support hair growth, per Times of India (2024).
Consistency: Expect reduced hair fall in 2–4 weeks and visible growth in 4–6 weeks, per BeBeautiful (2025).
Pro Tip: Add a few drops of lemon juice to your shampoo rinse to neutralize onion odor, per Reddit (2023).
Precautions to Keep in Mind
Onion oil is safe for most but requires caution:
Patch Test: Test on inner wrist for 24 hours; discontinue if redness, itching, or irritation occurs, per HealthShots (2020).
Moderation: Use 2–3 times weekly to avoid scalp irritation from sulfur, per BeBodyWise (2022).
Avoid Eyes: Onion juice can sting; rinse thoroughly if contact occurs.
Sensitive Scalp: Consult a dermatologist if you have eczema, psoriasis, or sensitivity, as onion oil may cause dryness or irritation.
Source Quality: Use organic onions and high-quality carrier oils to avoid pesticides or contaminants.
Not a Cure: Effective for mild hair loss or slow growth but not a substitute for medical treatments for conditions like alopecia, per Healthline (2023).
