What kind of garbage is hair dye that has not expired or used up?
Hair dyes that have not expired are hazardous waste. Because hair dye contains chemicals such as p-phenylenediamine, which can cause direct or potential harm to the human body and the environment, it is a hazardous waste. Remember, unused and expired hair dye should be disposed of in the red hazardous waste container.
What are the dangers of hair dye
1. The infiltration of toxic substances will damage the liver and kidneys. Some hair dyes contain lead acetate, silver nitrate, benzene, naphthalene, phenol and other ingredients, which can cause damage to the liver and kidneys when they penetrate into the skin.
2. Cause hair loss. Hair dye has a certain irritation, which can lead to an inflammatory reaction in the scalp and hair follicles, which will cause the hair follicles to shrink over time, and the hair will grow from coarse to thin, and finally fall out.
3. Skin allergies. This is one of the most common reactions after perming. The main phenomenon of allergic reactions caused by hair dyeing is contact dermatitis. Due to the prolonged heating of the scalp, it aggravates the allergic reaction and irritation of the skin. Try to choose hair dyes that are pure natural plants.
4. Change the hair quality. When you dye your hair, you will lose the balance of moisture in your hair, and a large amount of protein will be denatured and reduced. As a result, the hair becomes brittle, the fibers break, and loses its natural softness, toughness and shine.
