Masks and Rinses Part 4: Onion Juice Rinse for Natural Hair

Hello lovelies!

I know it’s been a minute since I was here and we can blame work for that. However, I am putting measures in place to ensure that the posts are more consistent. I hope you will stick around for that. 🙂

So, we have been covering masks and rinses over the past few weeks. Today I want to continue with that. I think I only have two more to cover before the series take a break.  This week we will be looking at the onion juice rinse, which is one of my favorites.

Benefits of the Onion Rinse

  • Antibacterial Properties: This helps to treat the scalp which in turn helps to reduce itchiness. My scalp is sensitive and I have seen the juice work wonders by extending the number of days I can take in between wash days.
  • Controlling Dandruff: This goes hand in hand with the first point as a result of the antibacterial properties.
  • Promotes Hair Growth: This rinse helps to accelerate/ boost hair growth because it promotes blood circulation. In addition to this, a healthy scalp is also likely to enjoy unhindered hair growth.
  • Adds Shine: I don’t know how to explain this but it definitely adds shine to your hair. I first saw this in action from the Green Beauty Channel. She has a detailed video showing her results after using the rinse for about a year. After that, I started using the juice regularly and have definitely seen a difference. I believe the shine from the photos in this henna mask post was a combination of the henna and continued use of the onion juice rinse.

Preparing the Rinse

Now that you know the benefits of using this rinse, it’s time to figure out how to prepare it. There are two main ways:

  • The blender method

This method is pretty simple. All you need is one red/ purple onion, two cloves of garlic and a teaspoon of cayenne pepper. You could also add about quarter or half a cup of water depending on the desired potency of the rinse. Blend all the ingredients together and strain to remove any strings or chunks. Voila! You have your onion juice.

  • The boiling method

For those without blenders, you will still need the same ingredients: quarter or half a cup of water, one red onion, two cloves of garlic and a teaspoon of cayenne pepper. Place the ingredients in a pot then bring the mixture to boil. Let it simmer for a minute or two then turn off the heat. Let the mixture cool down then strain it to get your onion juice.


In both methods, it is IMPORTANT to vary the amount of cayenne pepper to suit your hair and scalp. The first time I did this, I put more than a teaspoon and I felt like my head was on fire. So start small (less than a teaspoon) and build up to what you are comfortable with.

As with any hair or skin treatment, it is also important to consult your doctor in case you have any underlying conditions or allergies. Additionally, always do a patch test on the inside of your elbow before you proceed. This way you get to rule out or at least reduce the chances of having any adverse reactions.


  • Part your hair into sections for easier application
  • Apply the mixture from the scalp, roots and work your way along your hair strands
  • Let it sit for about 15-30 minutes depending on what you are comfortable with
  • Rinse it out and shampoo your hair as usual to clean your scalp and get rid of the pungent smell that comes with onions
  • Proceed with the rest of your hair regimen

I use the rinse once every fortnight to ensure that my scalp is as healthy as possible. As I mentioned earlier, my scalp is sensitive and tends to be itchy by the third day because of products, smoke, dust and the likes. With the onion juice rinse, I’m able to ward off the irritation up to about day five or six when wash day is just around the corner.

I think that’s about it when it comes to this rinse. Let me know if you’ve ever tried it, if it’s worked for you or backfired horrendously. That said, let’s keep the conversation going here or on social; my handles are linked below. 🙂
