Be careful, using this thing on a woman's head may be a dangerous thing!

In recent years, hair dye has become a very common commodity, especially loved by female friends, who think that with hair dye they can easily dye their hair at home. However, they have not discovered the hidden dangers in hair dye.

Hair dyes can cause allergies or anemia

I've heard that some people even dye their children's or pets' hair. The substance used in hair dye is called paraphenylenediamine (PPD), which is necessary for dyeing hair black. This substance can cause a strong allergic reaction.

When the accumulated chemicals in the body reach a critical point, allergic reactions will occur in the form of skin diseases. However, PPD is too potent and has the risk of causing acute shock and systemic anaphylaxis.

In addition to allergic reactions, p-phenylenediamine also causes contact dermatitis, mucosal edema, conjunctivitis, rhinitis, bronchial asthma and other diseases. After entering the human body, paraphenylenediamine destroys enzymes and may cause anemia or renal dysfunction.
