Onions contain a great amount of calcium, iron, sulfide, and vitamins, and the consumption of onions is known to help reduce blood fat, prevent hypertension, and destroy bacteria. In addition to being used as food, onions can also be used as a hair dye.
Natural hair-dyeing agent
Most hair-dyeing agents are made of synthetic ingredients and bring negative impacts to human health. When onion is used as a hair-dyeing agent, it is biologically safe, as onions do not carry any carcinogens. The only possible drawback is that the user has to bear the pungent smell.
- Peel off the purple onion skins and soak them in water.
- Wait until the water changes color before using it to dye your hair.
Such a natural dyeing agent is safe, and the color can last one to two months.
