Onion oil has become a popular natural remedy in hair care due to its ability to strengthen hair roots, promote growth, and reduce hair fall. Derived from onion extract infused into nourishing carrier oils, onion oil combines traditional wisdom with modern hair care needs, making it a powerful solution for thinning, dull, and damaged hair.
Onion oil is made by extracting
the goodness of onions (Allium cepa) and blending it with base oils like
coconut oil, sesame oil, or castor oil. Rich in sulfur and antioxidants, onion
oil supports scalp health and improves hair strength from the roots.
