 Onion Oil and onion's juice for hair growth. How to make and use?

The effectiveness of onion juice and onion oil for hair growth is supported by limited scientific evidence and a fair amount of anecdotal success stories. Here’s a deeper look into what is known about their potential benefits and limitations:

Scientific Evidence:
Onion Juice:

A small study published in the Journal of Dermatology in 2002 showed that applying onion juice to the scalp could help with hair regrowth in people with alopecia areata, a condition that causes hair loss. In the study, 74% of participants who used onion juice experienced some degree of hair regrowth after four weeks, and 87% saw hair regrowth after six weeks.

Onion Oil:

There are no extensive clinical studies specifically on onion oil, but the beneficial compounds in onions (such as sulfur, antioxidants, and antimicrobial agents) are retained in the oil and can theoretically support hair health and growth.

Mechanisms of Action:

Sulfur Content: 

Both onion juice and onion oil contain sulfur, which is a key component of keratin, the protein that makes up hair. Sulfur can strengthen hair and promote its growth.
Antioxidants: Onions contain antioxidants like quercetin, which can reduce inflammation and protect hair follicles from oxidative stress.
Antimicrobial Properties: Onions have antibacterial and antifungal properties that can help maintain a healthy scalp, potentially preventing conditions that could hinder hair growth.

Anecdotal Evidence:

Many individuals claim positive results from using onion juice or oil, reporting increased hair growth, reduced hair loss, and overall healthier hair.

Practical Considerations:

Preparation:

Onion Juice: Blend onions and strain the juice.

Onion Oil:

Simmer chopped onions in a carrier oil and strain after cooling.

Application:

Apply to the scalp and massage gently.
Leave on for at least 30 minutes; some prefer overnight application.
Wash thoroughly to remove the strong odor.
Safety and Side Effects:
Patch Test: Always perform a patch test to check for allergic reactions or scalp sensitivity.
Smell: The strong odor of onions can be off-putting and difficult to wash out.
Consistency:
Regular use (2-3 times a week) over several weeks or months is necessary to potentially see results.

Conclusion:

While there is some scientific support and plenty of anecdotal evidence suggesting that onion juice and onion oil can promote hair growth, results can vary from person to person. If you choose to try these remedies, be consistent and patient, and monitor your scalp's reaction to avoid irritation or allergies.
