How to make onion oil

Cutting off the ends of the onion

1. Prep your onion

Start by cutting the ends off of a medium onion and then peel off the first layer.

Cutting and dicing the onion

Then, cut and dice your onion because we’re going to need to blend it.

Scooping three tablespoons of coconut oil

2. Prep your coconut oil

Scoop out three tablespoons of coconut oil and then pop it into the microwave for 30 seconds to melt it down.

3. Blend

Add all of the cut onions and the coconut oil, leaving a little bit for later, to the blender.

Blend until you have a very thick, pasty texture like this.

Frying the onion oil mixture in a pan

4. Fry

Add the leftover coconut oil to a pan and fry the onion paste over low heat for about 15 minutes. Keep mixing so it doesn’t burn underneath. You’ll want to mix until it gets to a kind of brown color.

5. Filter

Place a cheesecloth over a bowl and put the onion paste on the cloth. We’re going to use this to squeeze out all of the oil which is going to be our onion hair oil.

This onion oil nourishes your scalp, helps improve blood circulation and ensures thicker and stronger hair.

Filtering the onion oil

Squeeze out all of the oil that’s in it. The reason we’re using the cheesecloth is because we don’t want any residue in the oil. 

Adding drops of essential oil

6. Add essential oil

To finish the oil, add a few drops of essential oil to your mixture. I like to use juniper berry, peppermint, or tea tree oil because it helps kill the scent of the onion.

I don’t recommend using any fruity sort of essential oils because they might not be strong enough to cover the onion.

Pouring the onion oil into a bottle

7. Bottle

Store your oil in a little container and you’re done!

Benefits of onion oil

Onion oil is really high in sulfur and that means you can use it to treat bald patches or thinning hair. This is a great oil to add to your hair routine because it really does help and I swear by it.

Another tip for people who have thinning hair is to make sure you’re not stripping it a lot, so that means less shampooing and more conditioning and making sure your hair has plenty of nutrients.

How to apply onion oil to hair

When applying the oil, you want to apply it to your hair right before washing. If you’re using it as a hair growth remedy, apply it to your scalp before a hot oil treatment as this will treat your scalp and the hair follicles.

Alternatively, if you already have an onion spray, you can use the oil as a hot oil treatment. To do this, apply as-is without and just wear a plastic cap overnight and wash it off the next day. That’s how I prefer to use it.
