Red onion juice isn’t just a folk remedy—it’s a science-backed solution brimming with compounds that your hair and scalp will love. At its core, red onion juice is a treasure trove of nutrients that work together to combat hair loss, promote growth, and enhance overall hair health. Let’s break down the key players that make this kitchen staple a hair care superstar.
Sulfur is the hero ingredient in red onions. This essential mineral is a building block of keratin, the protein that forms the structure of your hair. Without enough sulfur, your hair can become weak, brittle, and prone to breakage. By applying red onion juice to your scalp, you’re delivering a concentrated dose of sulfur directly to your hair follicles. This helps stimulate collagen production, which repairs and strengthens damaged follicles, giving your hair a solid foundation for growth. Plus, sulfur boosts blood circulation to the scalp, ensuring your hair roots get the oxygen and nutrients they need to thrive.
