Onion juice has been the subject of lengthy and ongoing discussion regarding both its potential benefits and potential drawbacks for hair. In spite of the fact that there are those who swear by the benefits that onion juice can have for hair, there are also those who insist that there are negative effects that onion juice can have on hair.

Most people are not surprised to learn that onion juice can be used on their hair to promote hair growth because this practice has been around for centuries and is considered to be effective.

Onion juice contains a significant amount of sulphur, which is an essential nutrient for the development of long, healthy, and shiny hair. On the other hand, due to the potent nature of this sulphur, the consumption of onion juice may have some unintended consequences for one's hair.

Read on as we dispel some myths about the benefits of onion juice for hair and provide some facts in its place:

Onion Juice For Hair Growth 

 The question that we get asked the most frequently is whether or not onion juice promotes hair growth. We say, yes! When onion juice is applied directly to the scalp and hair, the sulphur that is present in the juice stimulates hair growth as well as the production of collagen in the scalp, which results in hair that is longer and shinier. Onion juice has not been shown to have any adverse effects on hair in any way, shape, or form.

Onion Juice And The Appearance Of Grey Hair  

We hear a lot of people suggesting that one of the side effects of onion juice on the hair is that it turns hair grey. This is one of the side effects of onion juice on the hair. In point of fact, it is the complete opposite. The onion juice contains antioxidants that help prevent premature greying of the hair and also delay the process of greying that occurs naturally.

Apply It Before Going To Bed 

Many individuals give the onion juice time to work on their hair by leaving it on overnight. They claim that it yields the best results possible. But experts suggest not doing so. If you leave the juice on your scalp for an extended period of time, it may cause your scalp to become irritated. In order to prevent this adverse effect of onion juice on hair, we recommend that you massage the juice into your scalp for 15–20 minutes before washing your hair thoroughly with a shampoo that is designed for sensitive skin.

You should probably avoid using onion if you have a scalp that is easily irritated and sensitive because the negative effects that onion juice can have on hair can be quite severe.

If your hair is rough, dry, or acting strange, try spritzing some rose water on it and seeing if that helps. In this way, the negative effect that onion juice has on hair will be mitigated.

You can also apply onion juice to your beard for additional benefits. It contributes to the thickening of the beard hair and encourages the growth of new beard hair at the same time.
