Follow these remedies for beautiful hair. However, onion juice may irritate sensitive scalp and cause adverse reactions. Read on for details on onion juice side effects in the next section.

Side Effects Of Using Onion On Your Hair

Using onion on your hair can have side effects. While onion juice’s sulfur content can nourish hair follicles and help with dandruff, it can be strong for sensitive scalps, leading to irritation, itching, and redness. You can easily prevent these issues by diluting onion juice with carrier oils like coconut or olive oil or by combining it with aloe vera gel.
