can we leave onion juice on hair overnight - #12944

Aasha

I am really curious about onion juice for hair stuff. A while ago, I started having hair thinning issues, which has been super frustrating. A friend suggested trying onion juice, claiming it works wonders for hair growth. I mean, I’ve heard about this remedy for ages, but wasn’t sure how to use it exactly. Anyway, I decided to give it a go and applied some onion juice to my scalp one evening, but that got me thinking... can we leave onion juice on hair overnight without causing any issues? I've read some places that it can be pretty potent, so I wasn't sure if that would be too harsh for my scalp. Also, I've been experiencing some irritation with other products before, so the idea of leaving onion juice on for hours kinda freaks me out a little. Like, do you think it gets too strong when it's on for too long? Or would it be better to wash it out after a couple of hours? Could there be any bad side effects? I mean, I'm just trying to find a solution without messing up my hair more. Any thoughts on what’s the best approach here?

Doctors’ responses

Leaving onion juice on your scalp overnight could be too intense for some people, especially if you have a sensitive scalp or have experienced irritation with other products before. Onion juice contains sulfur compounds, which are believed to boost hair growth by improving blood circulation to the hair follicles, but these compounds can also be quite strong and potentially irritating. If you’re concerned about irritation or have had previous sensitivity, it might be better to start with a shorter application time. You could apply the juice for about 15-30 minutes initially, then gradually increase the duration to see how your scalp reacts. This way, you’re giving your scalp time to adjust without overwhelming it.

It’s important to note that while some people have found success with onion juice, there’s limited scientific evidence to support its effectiveness, and results may vary from person to person. If you choose to try it, make sure to patch test on a small area of your scalp before fully applying it to ensure you don’t have any adverse reactions. Also, be sure to wash your hair thoroughly with a mild shampoo after applying to remove any residue.

If you experience any itching, burning, or redness, it would be wise to discontinue use and explore other alternatives. There are various medical treatments for hair thinning, such as minoxidil, which has more substantial evidence backing its efficacy. Consulting with a dermatologist or healthcare professional might be beneficial in discussing more traditional options if home remedies don’t work for you.
