Onion Oils For Hair Growth – A Buying Guide

There is no doubt that onion oil is highly beneficial for your hair. However, you can boost its results by applying it in a proper manner. Check the step-by-step guide to applying onion oil in the next section.

How To Apply Onion Oil

Step 1: Prepare Your Hair

Comb your hair thoroughly to remove all knots and tangles. You can apply oil both to dirty and clean hair.

Step 2: Section Your Hair

Divide your hair right down to the middle of your scalp and again from left to right. This will make it easier for you to apply the oil.

Step 3: Treat Your Roots And Hair

Take one tablespoon of the oil in your palm, rub it between your hands, and run your fingers through the length of your hair. Leave the oil in for a couple of hours before washing it out with a mild shampoo. Though onion oil is great for your hair, you also need to be aware of its potential side effects. Check them out below.

Side Effects Of Onion Oil

Anecdotal evidence suggests that onions add tamas (low energy) to your body. This is why many people avoid using onion daily, be it in food or for other purposes. Another major downside to onions is their pungent smell, which does not fade even hours after application. After applying onion hair oil, you need to wash your hair and scalp at least two times to get rid of the smell. However, if the oil sits well with you, proceed to use it as instructed. Can I use onion hair oil every day? Yes. But be aware of the pungent smell it leaves behind. Usually, applying it three times a week should suffice. Can I leave onion oil on my hair overnight? Yes, but make sure to do so just three times a week in the recommended quantity. How can I get rid of the odor after applying onion oil to my hair? Use the oil in the recommended quantity and for the suggested time period. If the smell still persists, wash your hair with a clarifying shampoo.
