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

Hair fall, thinning strands, and slow growth are among the most common hair concerns today—often triggered by stress, pollution, poor diet, hormonal shifts, or overuse of harsh products. While store-bought treatments promise quick fixes, many people are turning back to nature for gentler, more sustainable solutions. One remedy that has gained remarkable attention is onion hair oil—a simple, affordable, and surprisingly powerful DIY treatment rooted in traditional care.

In this in-depth review, we’ll explore why onion oil works, how to make it properly at home, how to use it for best results, and what to expect over time—so you can decide whether this natural remedy deserves a place in your hair-care routine.

Why Onion Hair Oil Is a Game-Changer for Hair Health

Onions may not be glamorous, but their nutrient profile is impressive—especially when it comes to scalp and hair health.

1) Rich in Sulfur for Stronger Strands

Onions are naturally high in sulfur, a key mineral involved in collagen production. Collagen supports the structure of hair follicles, helping strands grow stronger and thicker over time. Sulfur also improves keratin formation, which is essential for resilient hair.

2) Improves Blood Circulation to the Scalp

When massaged into the scalp, onion oil can stimulate blood flow. Better circulation means more oxygen and nutrients delivered to hair follicles—an important factor for faster, healthier growth.

3) Antibacterial and Antifungal Properties

A healthy scalp is the foundation of healthy hair. Onion compounds help combat dandruff, scalp infections, and buildup that can clog follicles and slow growth.

4) Helps Reduce Breakage and Hair Fall

Regular use of onion oil nourishes the roots, strengthens the hair shaft, and reduces brittleness—leading to less breakage and visible hair fall over time.

How to Make Onion Hair Oil at Home (Step-by-Step)

Making onion hair oil at home is straightforward and gives you full control over ingredients—no preservatives, no harsh chemicals.

Ingredients

• 1 large red onion (or 2 small ones)

• 100 ml coconut oil (olive oil or castor oil also work well)

• Optional: 5–8 drops of essential oil (rosemary, lavender, or tea tree) to help neutralize the onion scent

Instructions

1. Prepare the onion: Peel and chop the onion into small pieces.

2. Extract the juice: Blend or crush the onion and strain to collect the juice (you can also use the pulp for a stronger infusion).

3. Heat the carrier oil: Pour your chosen oil into a pan and warm it gently over low heat.

4. Infuse the onion: Add the onion juice or pulp to the oil and let it simmer for 5–10 minutes. Do not overheat.

5. Cool and strain: Allow the oil to cool completely, then strain it into a clean, dry glass bottle.

6. Store properly: Keep the oil in a cool, dark place. It stays fresh for up to 2 weeks.

Pro tip: If you prefer a milder smell, add essential oils after the mixture cools.

How to Use Onion Hair Oil for Best Results

Consistency matters more than quantity. Here’s a routine that works for most hair types:

1. Apply to the scalp: Section your hair and apply the oil directly to the scalp, focusing on the roots.

2. Massage gently: Use your fingertips to massage for 5–10 minutes. This boosts circulation and helps absorption.

3. Let it work: Leave the oil on for at least 30 minutes. For deeper conditioning, leave it overnight with a shower cap.

4. Wash thoroughly: Rinse with a mild, sulfate-free shampoo. You may shampoo twice if needed.

5. Frequency: Use 2–3 times per week for optimal results.

What Results Can You Expect—and When?

While results vary based on genetics, diet, and overall hair care, many users report noticeable improvements with regular use:

• Within 2 weeks: Reduced hair fall and less shedding during washing

• Within 4–6 weeks: Baby hairs and visible growth along the hairline

• After 8 weeks: Thicker texture, improved shine, and stronger strands

Remember, natural remedies work gradually. Patience and consistency are key.

Common Questions About Onion Hair Oil
