What Is Boiled Onion Water for Hair?
Boiled onion water is a liquid made by simmering chopped onions in water and then straining it. Onions contain sulfur compounds and antioxidants that some studies suggest may support scalp health and hair growth.
How It May Help Hair Growth
Research indicates that topical onion juice can improve blood circulation to the scalp and provide nutrients that support hair follicles. A small study published in the Journal of Dermatology found that participants using onion juice saw modest improvements in hair regrowth compared to a control group.
How to Use Boiled Onion Water Safely
To prepare it, boil chopped onions in water for 10 to 15 minutes, cool the liquid, and apply it to the scalp. Rinse thoroughly after 30 minutes. For best results, use it consistently and consult a dermatologist if you experience irritation or have sensitive skin.
