What are the dangers of dyeing hair during menstruation?

Many young people have the habit of dyeing their hair, especially young women. They will dye their hair into different colors and create different head shapes every once in a while, which makes them look very individual. However, here we would like to remind young people that there are many things to pay attention to when dyeing hair. First of all, no one can dye their hair frequently. Frequent dyeing of hair will lead to deterioration of hair quality. In addition, you must choose hair dyes of qualified quality. Never choose inferior hair dyes for the sake of cheap prices. These long hair dyes are all chemical substances. Long-term contact with the human body will cause many harms. Especially women should not dye their hair during menstruation, otherwise, the following harms may occur.

First, it may cause cancer

Researchers at Yale University in the United States once surveyed women who started dyeing their hair before 1980 and found that more than one-third of them would develop lymphoma. Another survey of 13,000 women who dyed their hair by the American Cancer Society showed that their risk of developing leukemia was 3.8 times higher than that of women who did not dye their hair. However, a 40-year study conducted by Spanish scientists found that hair dyes only slightly increase the risk of cancer. Experts say that there have been many studies internationally on whether hair dyeing causes cancer, but there is still controversy as to whether it does. However, since the late 1970s, some ingredients in hair dyes that have been shown to cause tumors have been gradually eliminated from their formulas.

Second, skin allergies

Experts say that paraphenylenediamine is the main ingredient of hair dye. It can make the dyed hair color more solid, but it is also a strong allergen and can cause skin allergies in people with sensitive constitutions, among which contact dermatitis is the most common. In EU countries such as France and Germany, p-phenylenediamine has been explicitly banned from being added to hair dyes, but in my country, it is still used. Experts say that as long as hair dye complies with national standards and is used in appropriate amounts as required, it is safe.

Third, damage to the liver and kidneys

Experts say that some products on the market add heavy metals such as lead, mercury, and arsenic to enhance the dyeing effect. The lead content in some products is even 5-10 times that of paint. Long-term use will cause chronic damage to the body. Not only may symptoms of lead poisoning such as dizziness, numbness of the limbs, and abdominal pain occur, but the functions of organs such as the liver and kidneys may also be damaged.

Fourth, aggravate hair loss

Many patients suffer from hair loss due to frequent hair dyeing. This is because the benzene compounds such as p-phenylenediamine in some hair dyes can penetrate into the cuticle, an important component of the hair, and cause a peroxidation reaction, which can lead to dry, broken and even hair loss.
