Why Onion Oil for Hair Growth Works
The Science Behind Onion Oil
Onions are rich in sulfur, a mineral that plays a critical role in collagen production. Collagen supports healthy hair follicles, which in turn promotes hair growth. Onion oil also contains antioxidants such as flavonoids and compounds like quercetin that help reduce scalp inflammation and protect hair from oxidative stress.
Benefits of Onion Oil
- Stimulates Hair Growth: By boosting blood circulation in the scalp.
- Strengthens Hair Roots: Sulfur nourishes follicles and reduces breakage.
- Fights Scalp Infections: Its natural antimicrobial properties may help maintain scalp health.
- Delays Premature Graying: Antioxidants help preserve natural pigment.
- Adds Shine and Softness: When blended with carrier oils, it leaves hair nourished and smooth.
Traditional Wisdom Meets Modern Use
In Ayurveda, onion oil has long been massaged into the scalp as part of rejuvenating hair care rituals. Today, beauty enthusiasts are rediscovering this age-old practice with proven results.
