How can I dye my hair healthily?
Watch together!
Frequent hair dyeing brings health risks.
As household hair dyeing products gradually occupy the market, many people prefer this cost-effective self-dyeing method. While bringing convenience, it will also cause certain harm to the human body.
1 Skin allergy
As the main component of hair dye, p-phenylenediamine can make the dyed hair color stronger, but it is also a strong allergen, which easily leads to skin allergies, among which contact dermatitis is the most common.
2 aggravate hair loss
One of the reasons for hair loss is frequent dyeing of hair.
Because some hair dyes contain benzene series compounds, which can penetrate into the important part of hair-the stratum corneum, and undergo peroxidation, resulting in hair drying, breakage and even hair loss.
3 liver and kidney damage
Although the quality and safety of hair dyeing products have been improved in recent years, some products will add heavy metals such as lead, mercury and arsenic to enhance the dyeing effect, and some products even contain 5 10 times as much lead as paint.
Regular use will cause chronic damage to the body, which may not only lead to dizziness, numbness of limbs, abdominal pain and other poisoning symptoms, but also damage the functions of organs such as liver and kidney.
