• Sulfur is essential for the regeneration of hair follicles (1). You can add sulfur in your hair care routine with onion juice. It helps nourish your hair follicles with its rich content of sulfur.

Doro Cubillo, a YouTuber, embarked on a one-week experiment of applying onion juice on her hair and recorded her experience in one of her vlogs: “If you thought that the egg hair mask was smelly, let me tell you something, you haven’t put onions on your hair.” The adverse smell did not deter her from using it, and she noted a decrease in hair loss as a result of the onion juice treatment (i).

However, onion juice may not work for all. Tanya Wilson, a blogger, shared her experience after using onion juice in her hair care routine: “This may help on occasional use, but long term use, I have not found it to be beneficial (ii).”
