How Onion Juice May Be the Secret to Preventing Hair Loss

Onions are way healthier than you think

When most people hear about using onion juice to fight against hair loss, they have the same question: “why onions?” Even if you’re willing to accept the health benefits of everyday items in your pantry, you may not think of onions as the healthiest vegetable in your house.

If that’s how you think about onions, though, then it’s time to revise that opinion. It turns out that onions are full of fiber and probiotics that help to boost your digestive system. On top of that, they are full of antioxidants, which help your body fight off cancer and other diseases. Finally, onions are naturally anti-inflammatory, which helps your body stave off a number of issues caused by chronic inflammation (including arthritis, Alzheimer’s, diabetes, and even obesity).

Of course, those are all benefits that stem from eating onions. If you want to fight against hair loss, though, you’ll be putting onion juice directly on your head. Now, let’s take a closer look at exactly how all of this is supposed to work.

How do onions help fight hair loss?

In order to understand how onion juice fights hair loss, you need to understand more about what causes hair loss. When people lose hair, it is often due to inflammatory disease, bad diet, or poor blood flow. Onion juice is naturally antiseptic and helps to stimulate hair follicles and encourage hair to grow in areas where the above conditions have caused it to fall out.

As an added bonus, putting onion juice on your scalp helps to fight off bacteria or infections that may be affecting your scalp. Not only does this keep your scalp healthier in general, but the removal of such bacteria and infections can stimulate hair growth for the simple reason that bacteria and infections often prevent follicles from growing more hair.

Right now, most of what we know about onion juice fighting hair loss is anecdotal and comes from men and women sharing their stories online. However, it’s worth noting that the effectiveness of onion juice is rooted in sound, scientific theory.

Is there any evidence of onion juice preventing hair loss?

If you’re skeptical about using onion juice to fight hair loss, it’s probably because it sounds like yet another newfangled trend. In that case, though, you may be interested to know that the effectiveness of onion juice was put to the test many, many ago!

As reported by Vegamour, there was a study almost 20 years ago focusing on helping patients with alopecia areata regrow their hair. As part of the study, patients had to put onion juice on their scalps twice a day for a period of two months. The final results were astounding: when the trial was only halfway over, 74% of participants experienced hair regrowth. And a couple of weeks later, that number jumped to 87%!

Which celebrities are hyped about onion juice?

When it comes to weird new health and beauty routines, it’s understandable to be skeptical. It seems like every day, random would-be influencers are unveiling strange new beauty and wellness techniques in the quest for viral fame.

When it comes to onion juice helping fight hair loss, though, the idea is already being championed by some fairly big names, including Cardi B. As you may or may not already know, this celeb is an expert when it comes to hair masks, and her words carry quite a bit of weight.

She even got so into the idea that she shared her secret with Instagram: boiling onions in water and then using that water to wash her hair.

How to add onion juice to your haircare regimen

If you’re interested in fighting hair loss with onion juice, nothing keeps you from copying Cardi B’s technique. However, if you’d like to use the original technique that broke the internet, it only takes a few quick steps.

All you have to do is dice some onions in a blender and then blend them into a liquid. From there, you add the liquid to your scalp twice a day for a minimum of 30 minutes at a time. You may get even better results if you can leave it on overnight, but either way, this trick may help you achieve thicker, fuller, and more extravagant hair.
