According to reports, if you’re allergic to onions, it’s best to avoid using onion juice. Onion juice can cause skin irritation, such as redness and itching, especially if the mixture is very strong. To minimise this risk, you can mix onion juice with soothing ingredients like aloe vera or coconut oil.

Can onion juice help with hair loss?

Onion juice may help with hair loss due to its high sulfur content, which is essential for growing strong hair. Sulfur-rich proteins like keratin support hair growth, and onion juice can provide an extra boost of sulfur to promote thick and healthy hair.The sulfur present in onions may also encourage collagen production, which helps develop healthy skin cells, and possibly encourage hair growth. Also, onions help improve circulation, and applying onion juice to the scalp could increase blood flow to hair follicles. However, more research is needed to confirm the significance of these findings.Also read | Is icing your face safe and effective? Know its benefits, risks, and application tips
