Red onion is believed to promote hair growth due to its high sulphur content. Sulphur is essential for the production of keratin, the protein that forms the structure of hair strands.
Applying red onion juice to your scalp may enhance blood circulation in the hair follicles. Improved blood flow can nourish the hair follicles, potentially leading to healthier hair growth.
Red onions contain nutrients like vitamins C and B6, folic acid, and potassium. These nutrients can provide essential nourishment for your hair, making it stronger and healthier.
Red onions possess antibacterial properties that can help combat scalp infections caused by bacteria. This can lead to a healthier scalp environment while reducing issues like dandruff.
The anti-inflammatory properties of red onions may help soothe scalp conditions such as itchiness, irritation, and inflammation.
Regular use of red onion on the hair can enhance its natural shine and lustre. This effect is due to the presence of sulphur compounds that promote healthy hair texture and sheen.
The natural pH of red onions is slightly acidic, which can help balance the pH of your scalp. A balanced pH level promotes a healthy scalp environment and can prevent issues like excessive oiliness or dryness.
By nourishing your hair follicles, promoting blood circulation, and providing essential nutrients, red onion may help reduce hair loss or thinning.
Red onion can act as a natural clarifying agent, effectively removing product buildup from your hair and scalp. This can improve the overall health of your hair and prevent clogged follicles.
The antioxidants present in red onions may help prevent premature greying of your hair by neutralising free radicals that contribute to hair ageing.
