Three Harms of Hair Dyeing

1, skin allergy

The main component of hair dye is p-phenylenediamine, which is a strong allergen, and people with allergies will have allergic reactions. At present, p-phenylenediamine is banned in many countries, but it is still used in China today.

2, aggravate hair loss

After dyeing hair, many people will suffer from hair loss, mainly because the chemicals in the hair dye will penetrate into the cuticle of hair, causing peroxidation, leading to dry skin and hair loss.

3. Damage to liver and kidney

Nowadays, many unscrupulous merchants in the market will add heavy metal components such as mercury, arsenic and lead in order to make the dyeing effect of products better. Give it to the hair dye agent in private. If these chemicals come into contact with the human body, they will bring harm to people's health, even seriously damage the liver and kidney and affect their functions.
