Hi, Does onion juice help hair growth? Is there any evidence behind this? Hair loss is a real concern. And that 60% of men will have to deal with hair loss by age 50, and that 50% of women will experience hair loss in their lifetime. So the need to find solutions to combat hair loss only becomes more and more common. But onion juice? In this video, we will look at why you should use onion juice for hair loss. Is there any research behind it, If so, how do we use onion juice for hair loss for the best results?


Onion Juice Has Been Used for Decades

So it turns out onion juice has been used for decades as a home treatment for hair loss. Even though you might pass up on it in your salads, not me, since I love onions, onion juice for hair, is a different story. So much so, that Cardi B, took it to Instagram, and shared that she uses it herself for her hair.

Let's just first take a look at why onion juice. What exactly does it do for the job? Most people who use it say it helps them restore their lustre and shine. Others say it helps with growth, prevents premature greying of hair, and can also treat dandruff when other products may have failed,

Why Onion Juice May Work

A lot of that is attributed back to its richness in antioxidants and flavonoids. Interestingly, onions also offer antimicrobial, antifungal, and anti-inflammatory benefits. Here is a visual of what research is being done on Allium cepa L, which is just fancy for onions. Quite a bit right, obesity, diabetes, neuroprotection, antioxidants, and so much more. I also made a video on onions and testosterone that I highly encourage you to watch after this one here.

One compound stands out for hair, though, which is that it's high in dietary sulfur. Sulfur is found within amino acids, which are components of proteins. When you have proteins, especially keratin, which is known to be sulfur-rich, they are needed for growing strong hair. Not to forget that the sulfur from onions may also help promote collagen production. And collagen in turn helps the production of healthy skin cells and hair growth, which we talk about a lot on this channel.

Is there any research on it?

But the real question is are there any studies that demonstrate that it works? Unfortunately, there are not many, but I did find one that I think is pretty interesting to look at. This study here involved 38 women and men who applied onion juice or tap water to their scalps twice daily for two months. Of the 23 participants who used onion juice, 20 people (or 87 percent) noticed regrowth by six weeks into the trial, while only two people from the tap water group noticed the same. However, the small sample size of this study means that further research is needed to fully understand this potential effect. Would be cool to see more published soon because the study is over 10 years old.


How to Use Onion Juice for Hair Growth

But let's talk about how to use onion juice to get the most benefits from it. And I know that some people may avoid using onion juice because of the strong smell it has. But the smell doesn't bother me, as much as the tears do. But, for this reason, you can try to curb the onion smell too.

To start: Combine 3 tsp of onion juice with 2 tsp of lemon juice. Once you do that, apply the mixture to your hair and scalp as evenly as possible, then, leave it in your hair and scalp for 30 minutes. Rinse and use a mild shampoo to reduce any onion smells. You can even mix the onion juice with an emollient like aloe vera or coconut oil if it causes any stinging on your skin. Since that can also occur.

Another way to prepare it is actually by chopping 3-4 onions into very small pieces, getting all the juice out of them, blending it, then applying the juice with a cotton pad while massaging it into the scalp, and letting it sit for an hour, then rinsing it off.


Combining Onion Juice with Hair Oils

I also made a video on the top 3 hair oils that you can use to hopefully speed up the process, that you can watch here.

The Potential Downsides of Using Onion Juice



While onion juice may offer some potential benefits for hair growth, it's important to also consider the potential downsides. For starters, the strong smell can be quite overpowering and difficult to get rid of even after rinsing. You may find yourself feeling self-conscious going out in public after an onion juice treatment.

Additionally, some people may experience skin irritation, redness, or a stinging sensation when applying onion juice directly to the scalp, especially if they have any cuts, scratches, or sensitivity. The compounds in onions that provide antimicrobial and antifungal benefits can also irritate the skin for some individuals.

There's also the issue of durability and consistency. Preparing onion juice at home means the concentration of the juice can vary significantly from application to application. Commercially prepared onion hair products may be more reliable but are also likely less potent than fresh juice.

Other Natural Hair Remedies

Of course, onion juice is just one of many natural home remedies people use for hair growth and maintenance. Other popular options include:

  1. Aloe vera gel - Contains vitamins that may help stimulate growth
  2. Coconut oil - Helps nourish hair and reduce protein loss
  3. Green tea rinses - Antioxidants may counteract hair loss
  4. Egg masks - Proteins in eggs can strengthen hair
  5. Cinnamon powder - May improve hair growth and thickness
The effectiveness of these remedies can vary from person to person. As with onion juice, robust scientific research on their hair benefits is still fairly limited.

When to See a Professional

If you are experiencing significant or rapid hair loss, home remedies like onion juice may not be enough to effectively treat the underlying cause. In these cases, it's a good idea to make an appointment with a dermatologist.

A dermatologist can evaluate your hair loss, get to the root of what's causing it, and recommend medical treatments if necessary. These may include prescription medications, laser therapy, platelet-rich plasma injections or hair transplantation surgery.

While natural remedies are generally safe to try, they shouldn't be used as a substitute for proper medical care when it's needed. Be open about any home treatments you're using with your dermatologist.
