What Is Onion Juice?

Onion juice is a potent, nutrient-rich liquid extracted from fresh onions (Allium cepa). Thanks to its high sulfur content, antioxidants, vitamins C and B, and potent antimicrobial compounds, onion juice has been utilized for centuries in folk medicine to promote hair regrowth, reduce dandruff, fight acne, and improve overall skin and scalp health. Its pungent aroma may not be to everyone’s liking, but its effectiveness continues to win new followers in the wellness community.

How To Make Onion Juice At Home

Making onion juice at home is straightforward and enables you to use the freshest, most potent product possible. Here’s a step-by-step guide for best results:

You Will Need

2-3 medium-sized fresh onions
A sharp knife
A juicer (manual or electric)
A grater or blender (as alternatives)
A fine muslin cloth or a fine-mesh strainer
A clean, medium-sized glass jar for storage
Paper towels

Preparation Steps

Peel the onions: Remove all outer skins and roots.
Rinse thoroughly: Hold the onions under running water to remove dirt and impurities.
Pat dry: Use a paper towel to dry the onions completely.
Cut into quarters: Slice the onions into quarters or manageable pieces to fit your juicer or blender.

Juicing Methods

Using a juicer: Place onion pieces into the juicer chute and operate as per manufacturer’s instructions. Collect the juice in the jar.
Using a blender: Add the onion pieces with a small splash of water. Blend until a smooth paste forms. Strain the blended onion puree through a muslin cloth or fine sieve, squeezing out as much liquid as possible into your jar.
Using a grater: Grate the peeled onions on the finest side. Place the grated onion pulp into a muslin cloth or sieve and press to extract the juice.

After juicing, wash all equipment thoroughly using hot, soapy water. Onion’s strong aroma tends to linger, so extra cleaning may be required.

Storage

Use freshly made onion juice for maximum benefits.
If storing, keep the juice in a tightly sealed glass container in the refrigerator for up to 2–3 days.

Pro Tips For The Best Squeeze

Use fresh, firm onions for higher yield and best potency.
Cutting onions into small pieces allows for easier and quicker blending or juicing.
Strain well—using a muslin cloth helps remove all solid onion residue for a smoother juice.
Always prepare juicer or blender for deep cleaning afterward to avoid lingering smells.
Onion juice can be strong; wear kitchen gloves and avoid touching your face during preparation.

How To Use Onion Juice: Skin, Hair & Health

Onion juice’s rich composition offers multiple ways to improve your self-care routine:

Hair: Encourages thicker, stronger hair growth, helps control hair fall, fights dandruff, and improves scalp circulation.
Skin: Used as a topical application to reduce acne-causing bacteria due to antimicrobial effects. The antioxidants present may help brighten skin and reduce pigmentation.
Health: Consumed in small doses, onion juice is said to boost immunity, aid digestion, and supply beneficial antioxidants, though internal use should always be discussed with a healthcare professional first.

Onion Juice Hair Packs & Remedies

There are several effective home remedies and topical packs using onion juice to address hair concerns. These methods can improve hair growth, reduce breakage, and restore scalp health.

1. Onion Juice and Honey Pack

Ingredients

1/4 cup fresh onion juice
1 tablespoon pure honey
A shower cap
A plastic bowl for mixing

Steps

Mix onion juice and honey in a bowl to form a thin paste.
Apply the mixture directly onto your scalp, massaging gently for 5 minutes with your fingertips.
Cover hair with a shower cap and leave the blend on for about 30 minutes for deep absorption. You can leave it on overnight for maximum results.
Rinse thoroughly with lukewarm water and a mild shampoo to remove any residue.

Frequency: Use this method twice a week to control hair fall and reinforce hair roots.

2. Onion Juice and Coconut Oil Treatment

Ingredients

1 tablespoon onion juice
1/2 tablespoon pure coconut oil

Steps

Mix onion juice and coconut oil in a clean bowl.
Gently massage into your scalp and through the length of your hair for about 5 minutes using slow, circular movements.
Soak a towel in hot water, wring out excess water, and wrap your head. Leave for 30 minutes to aid absorption.
Wash with a mild shampoo and warm water.

Benefits: This blend nourishes and soothes the scalp, improves the hair’s strength, adds shine, and combats dryness.

3. Direct Scalp Application (for Bald Patches)

Apply fresh onion juice directly to areas of thinning hair or bald patches using a cotton ball or spray bottle.
Massage gently for a few minutes and leave on for 20–30 minutes before rinsing.
Repeat 2–3 times a week for visible improvement in hair regrowth.

4. Onion Juice For Dandruff And Scalp Health

Add a few drops of tea tree oil or lemon juice to onion juice for extra antimicrobial power and a fresher scent.
Apply to the scalp, let sit for 30 minutes, then wash out thoroughly.

Onion Juice vs Onion Oil

Feature	Onion Juice	Onion Oil
Preparation	Raw, fresh juice extracted from onions	Infusion of onions with carrier oils
Odor	Strong, pungent, may persist	Milder aroma due to carrier oils
Active Components	High sulfur, antioxidants, direct nutrients	Enriched with benefits of carrier oils (e.g., coconut, castor)
Benefits	Intense stimulation for hair growth, scalp health	Moisturizing, reduces frizz, easier daily use
Application	Used for intensive treatment packs and spot applications	Convenient for regular oiling, less irritation
Storage	2–3 days refrigerated	Weeks to months

Choose onion juice for fast hair regrowth and scalp therapies, and onion oil for routine maintenance, moisture, and milder scent.

Side Effects & Precautions

Some individuals may experience itching, redness, or contact dermatitis when applying onion juice topically. Conduct a patch test on a small skin area before widespread use.
If irritation persists, discontinue use immediately.
Onion juice’s odor can linger; washing thoroughly with aromatic, sulfate-free shampoos helps reduce the smell.
For people with allergies to onions or related plants, avoid topical or oral use of onion juice.
Internal consumption should be approached with caution, especially for individuals with gastrointestinal sensitivities. Always consult a healthcare provider before oral use.

Frequently Asked Questions (FAQs)

How long does it take to see results from onion juice for hair growth?

Visible improvement in hair fall and growth can be noticed within 4–8 weeks of consistent application (2–3 times per week). However, individual results vary based on scalp condition and underlying causes of hair loss.

Will my hair smell after using onion juice?

Onion juice has a distinct, strong smell. Rinsing thoroughly with a fragrant, mild shampoo and using lemon juice or essential oils in the rinse can help mask the scent.

Can onion juice lighten or darken hair color?

There is no substantial evidence that onion juice affects hair color dramatically. Over time, it may enhance natural shine but not alter color significantly.

Is it safe to leave onion juice on the scalp overnight?

It is generally safe for most people to leave onion juice or onion juice-based hair masks overnight, provided no irritation occurs. Always use a shower cap to protect bedding and check skin sensitivity first.

Can I use onion juice every day?

For most, 2–3 times a week is sufficient. Daily use is not typically necessary and, for some, may cause irritation.

Are there alternatives if my skin is sensitive?

If onion juice is too strong, dilute it with rose water, aloe vera gel, or mix with gentle carrier oils like coconut or almond oil. Always patch-test before regular use.
