Is it worth it to smear this smelly juice on your scalp in hope of fantastic results? Experts say it is. Onion juice helps hair grow again for people who have a non-scarring form of hair loss. It doesn’t matter where on your head the problem is located, and it works well on both men and women. It takes two weeks to see little hairs sprout.

Who Does Onion Juice Work the Best For?

Onion juice works for most types of hair thinning and hair loss. It’s not so great for scarring alopecias, but those are pretty rare in most people. Scarring alopecias like frontal fibrosing or central centrifugal cicatricial disproportionately affect black women because of the many styling practices that involve tight pulling.

Even if you’re a victim of this kind of alopecia, you can still use onion juice on the areas that haven’t scarred yet. Hair follicles go through different phases before they die, and scarring takes place. Scarring looks stretched and shiny, so as long as you haven’t gotten to that phase, you can start grating your onions.

How Can You Make Onion Juice for Hair Growth?

There are three ways. The way to get the most potent juice is to grate your onions finely and squeeze the juice. Or you can throw chopped onions in the blender and sieve the juice out, but the quick action of the blender can evaporate some of the precious essential oils from the onion.

The third way is not juicing but making onion oil. In this method, you cover the chopped onions with olive oil and allow it to simmer on low for two to six hours. This way, your house will thoroughly smell like onions, but your onion oil won’t be nearly as potent.

How To Remove the Smell of Onions from Your Hands and Hair?

Before we get into how to use this stuff in your hair, you probably want to know how difficult it is to remove the smell. Wash your hands with soap right away to remove the odors. If that doesn’t work, smother them in apple cider vinegar. Wait a few seconds, rinse and wash with soap again. Phew.
