Why Onion Juice Works: The Science at a Glance

Why Onion Juice Works: The Science at a Glance

Onion juice is rich in sulfur, which helps rebuild keratin in hair, stimulates circulation to nourish the scalp, and strengthens roots to reduce shedding. It’s also packed with flavonoids and antioxidants that fight oxidative stress, soothe inflammation, and support scalp health. When applied consistently, these compounds work together to revive dormant follicles and maintain a healthy environment for new growth.

Here’s why people swear by it:

  • Boosts Hair Growth:
    Onion juice is rich in sulfur, a vital nutrient that supports the production of collagen and keratin—key proteins needed for healthy hair growth. By stimulating blood circulation to the scalp, it helps reactivate dormant hair follicles, encouraging new hair growth and reducing thinning.
  • Reduces Hair Fall and Breakage:
    The high sulfur content in onion juice strengthens hair strands from the inside out. It helps repair damaged hair shafts and prevents breakage, making your hair stronger and more resilient to everyday wear and tear.
  • Promotes a Healthy Scalp:
    Onion juice has natural antibacterial and antifungal properties that help balance the scalp’s microbial environment. This reduces dandruff, soothes scalp irritation, and prevents infections that can cause hair loss or slow down growth.
  • Improves Shine and Texture:
    Regular use of onion juice nourishes the hair cuticles, sealing in moisture and making strands smoother and softer. Over time, hair appears shinier, healthier, and more manageable.
