Introduction
Onion juice is a natural remedy that has been used for centuries to promote hair growth and treat hair loss. It contains several compounds like sulfur, antioxidants, and quercetin that are beneficial for hair health. Onion juice is thought to improve hair growth by increasing circulation to the scalp, regenerating hair follicles, and reducing inflammation. It’s a simple and inexpensive home remedy that many people find effective. Here is a step-by-step guide on how to make onion juice at home.
Benefits of Onion Juice for Hair
There are several ways that onion juice may benefit hair health:
- Promotes hair growth – Onion juice contains sulfur and quercetin which can help stimulate blood circulation to the scalp and regenerate hair follicles, leading to new hair growth.
- Prevents hair loss – The sulfur in onions has antifungal and antibacterial properties that may help treat infections and inflammation on the scalp that cause hair loss. It also contains antioxidants that protect hair follicles.
- Reduces graying – The large amount of catalase enzymes in onion juice neutralize hydrogen peroxide buildup in hair follicles which can cause premature graying.
- Adds shine – applying onion juice provides minerals like sulfur, phosphorus, and copper to hair strands, making them appear shinier.
- Conditions the scalp – Onion juice can soothe and condition the scalp by providing nourishment and reducing scalp infections.
Research suggests that applying onion juice to the scalp regularly can significantly increase hair growth in people with alopecia areata. It may also help with male and female pattern baldness.
Choosing the Right Onions
You can use most types of onions to make onion juice, but red and yellow onions are considered most beneficial for hair health. Sweet onions like Vidalia or Walla Walla are best as they contain the highest amounts of quercetin and sulfur. White onions have less sulfur so are not as effective.
When buying onions for juicing, choose fresh, firm bulbs without any mold, spots or soft spots. Avoid those that have started sprouting as they signify that the onion is past its prime. Organic onions are ideal to minimize exposure to pesticides.
Equipment Needed
Making onion juice only requires some basic kitchen tools:
- Onions
- Knife and cutting board
- Grater or blender
- Strainer
- Cheesecloth
- Bowl
- Spoon
- Storage container
A grater, blender or juicer can all be used to extract onion juice. A grater is good for making smaller amounts while a high-powered blender works best for larger batches. Cheesecloth and a strainer help separate the pulp from the juice.
How to Make Onion Juice
Here is a simple step-by-step method for making onion juice at home:
Step 1: Peel and chop the onions
Start by peeling the outer skin off the onions. Try to remove only the dry outermost layer and keep all the fleshy onion layers intact. This will provide more juice.
Next, chop the onions into quarters or smaller pieces. This makes them easier to grate and extract more juice.
Step 2: Grate or blend the onions
One option is to use a grater to grate the onion pieces over a bowl. A cheese grater or microplane works best. Grate them until you have a pulpy mass of onion in the bowl.
Alternatively, put the chopped onion pieces into a blender or small food processor. Pulse them into a pulp. This quickly extracts onion juice.
Step 3: Strain the onion pulp
Now you need to separate the juice from the solid onion pulp. Place a strainer over a bowl and line it with a few layers of cheesecloth. Transfer the onion pulp into the lined strainer.
Gather the edges of the cheesecloth together and twist to squeeze out all the onion juice into the bowl below. Wring the pulp until all liquid is extracted.
Step 4: Store and refrigerate the juice
Transfer the fresh onion juice into storage containers. Glass jars or bottles work well. Make sure to seal them tightly.
Fresh onion juice only lasts for a day or two. For longer storage, keep the juice in air-tight containers in the refrigerator for up to a week. It may also be frozen for several months.
Onion Juice Dilution Ratios
Onion juice can be used directly but it has a very potent and pungent taste. Most people dilute it before applying to hair. Here are some common dilution ratios:
- 1 part onion juice to 1 part water – for sensitive scalp
- 1 part onion juice to 2 parts water – for normal scalp and intermittent use
- Pure onion juice – for stubborn hair loss and thick scalp
Make sure to do a skin patch test before initial use to check for allergies. Leaving the juice on for 30-60 minutes allows the nutrients to be absorbed by the scalp.
How to Apply Onion Juice for Hair Growth
Here are some tips for using onion juice on your hair effectively:
- Shampoo and dry your hair first before applying onion juice.
- Use an eyedropper or spray bottle to distribute the juice evenly onto your scalp and throughout your hair.
- Massage your scalp with your fingers to improve circulation.
- Cover your hair with a shower cap and leave on for at least 30 minutes.
- Wash out the onion juice thoroughly with a mild shampoo.
- For best results, repeat two or three times a week.
The strong smell of onion juice dissipates from the hair within a few hours of washing it off. Using a good conditioner can also help reduce odors.
Onion Juice Hair Growth Recipes
To make the onion juice treatment more beneficial, you can mix in other ingredients like:
Onion Juice and Honey
The antibacterial properties of raw honey complement the benefits of onion juice. Mix 2 tablespoons each of onion juice and organic honey and apply to the scalp. Leave on for 30 minutes before washing.
Onion Juice and Olive Oil
Olive oil moisturizes the scalp and hair. Combine 1 tablespoon each of onion juice and extra virgin olive oil. Massage into the scalp and leave for 45 minutes before rinsing.
Onion Juice and Garlic
For a more potent recipe, grate one garlic clove into the onion juice. Garlic boosts circulation and sulfur compounds. Use in a 1:1 ratio with onion juice.
Onion Juice and Ginger
Ginger improves blood circulation to the scalp. Blend together 2 tablespoons each of onion juice and grated ginger. Apply to the roots of hair and leave for 1 hour before washing.
Onion Juice and Coconut Oil
Coconut oil moisturizes hair and reduces protein loss. Mix 1 tablespoon of onion juice with 2-3 tablespoons of melted coconut oil. Apply evenly and rinse after 20-30 minutes.
Onion Juice and Castor Oil
Castor oil nourishes the scalp and follicles. Combine 1 tablespoon each of onion juice and cold-pressed castor oil. Massage into scalp and let sit for 1 hour before washing out.
Onion Juice and Pepper
Black pepper increases blood circulation. Mix together 1 tablespoon each of onion juice and crushed black pepper. Apply to scalp and wash off after 45 minutes.
Side Effects and Precautions
Onion juice is generally safe when used topically but a few precautions should be taken:
- Do a patch test before initial use to check for skin irritation or allergic reactions.
- Avoid getting onion juice in eyes as it can cause stinging and burning sensations.
- Start with diluted onion juice and gradually increase concentration as tolerated.
- Rinse hair thoroughly after recommended duration to wash off all onion residue.
- Stop use if you experience scalp itching, skin rash or burning sensation.
- Keep out of reach of children.
People with known onion or garlic allergies should avoid topical use. Onion juice may also interact with certain medications like blood thinners. Consult a doctor before using if you have any medical conditions.
Does Onion Juice Really Work for Hair Growth?
There is limited research specifically on the efficacy of topical onion juice for hair growth. However, several small studies have shown promising results:
- A 2002 study found people with alopecia areata had significantly more hair regrowth after applying onion juice to the scalp twice daily for two months.
- A 2012 study in rats concluded that topical onion juice could induce faster and longer hair growth than minoxidil.
- A 2018 literature review reported that onion juice exhibits hair growth promoting effects comparable or superior to common hair loss medicines.
Many dermatologists also recommend onion juice to patients with alopecia and receding hairlines based on the antioxidant and antimicrobial properties. However, more large-scale human trials are still needed.
Consistency and regular use are key to seeing best results. It may take at least 4-6 weeks before noticeable improvement in hair growth from onion juice.
Conclusion
Onion juice is an easy traditional remedy that may hold potential for treating hair loss and promoting new growth. It can be made fresh at home by grating onions and extracting the juice. Refrigerating in air-tight containers preserves the active compounds. Dilute before applying and leaving on the scalp for 30-60 minutes 1-2 times per week. Onion juice should always be washed out thoroughly after use. Combining with other oils and herbs can enhance its effectiveness. While more research is still needed, onion juice is a safe, natural, and inexpensive option to try for improving hair health.
