How to Use Onion Juice for Hair Growth

Although many turn up their noses at the humble onion, if you’re suffering from hair loss, you may want to give this root vegetable another look. It may not sound appealing, but onion juice has been used for hundreds of years as a natural way to remedy hair loss and hair thinning. Science backed up these claims in a study published in 2002 in the Journal of Dermatology, in which hair regrowth was observed in almost 90% of patients who used onion juice. Try it for yourself, following the directions below, and you just might be (happily) surprised with the results.

Onion Juice for Hair Growth? Really?

Onions are extremely rich in sulfur, which is one of the primary building blocks of human hair. Sulfur also works to increase blood circulation (important for a healthy scalp) and to help spread nutrients throughout the entire hair follicle. Another bonus: sulfur may help slow or reverse graying of the hair.

Making the Onion Juice

Take 1-3 medium-sized onions (depending on how much you want to use, how much hair you have, etc.); peel them and dice them up.

Using a food processor, grater, juicer, or blender, extract the juice.

Take this juice and apply it directly to your scalp, massaging well, and drawing it through to the ends of your hair.

Let the onion juice sit for at least 15 minutes. Then, rinse out using lukewarm water and a mild, gentle shampoo. Voila!


Understandably, some people don’t enjoy the smell of pure onion juice. Luckily, combining the onion juice with honey will help make the product smell better without jeopardizing its efficacy. Add in one tablespoon of honey for every ¼ cup of onion juice. When adding honey, you’ll want to let the mixture sit on your head for at least 30 minutes, to make sure the onion juice is thoroughly absorbed.

If you’re really feeling adventurous, you can even leave the mixture on overnight, covering it with a shower cap while you sleep. As with the pure onion juice application, rinse with a mild shampoo and lukewarm water.

You can also add some lemon, rosemary, peppermint, or rose water to your onion juice solution to offset the smell, without the sticky mess of using honey.

Consistency is Key

Whether your onion juice rides solo or tags along with honey, it important to use the treatment on a regular basis. It’s best to repeat the process every day, but if that is too much of a burden, then at least a minimum of three times per week. It will take about two months of consistent use for noticeable results.

All in All

This natural remedy for hair growth really is effective, albeit it does take some time. Be consistent, and don’t give up. Also, be sure that when you are applying the onion juice that you are gently massaging your hair and scalp, and being equally gentle when rinsing the solution. The onion juice is most effective when it is fresh, so be sure to make the juice right before you plan on using it. If you’re consistent with your treatment, you should start to see noticeable improvement in as little as a few months.
