Why You Shouldn't Leave Onion Juice in Your Hair Overnight
While onion juice can be beneficial for hair due to its properties, leaving it on for extended periods, such as overnight, can cause irritation.
- Scalp Irritation: Onion juice has a high sulfur content, which, according to one reference, can irritate the scalp if left on for too long. This is especially true for individuals with sensitive skin.
- Recommended Usage: It's crucial to use onion juice as recommended and avoid leaving it on overnight.
