Experts from the University of London conducted a study, the results of which showed that chemicals in hair dyes lead to the formation of cirrhosis of the liver.

The authors base their conclusions on two series of studies, where one group of patients included 318 men out of 381 women with biliary cirrhosis occurring between 1997 and 2003. In addition, 2,258 out of 3,217 members from the National Support Center for People with the Disease entered the trial. And the third category consisted of 2438 out of 3933 randomly selected people who were used as a comparison. All three groups of volunteers completed questionnaires about potential environmental and genetic risk factors associated with hair dye. It turned out that autoimmune diseases such as rheumatoid arthritis, hyperthyroidism, cirrhosis and celiac disease were more common among those who used hair dye at least once a month over the past five years. In addition, it was found that the risk of developing these pathologies was highest among individuals with an unfavorable family history, reports

It turned out that when exposed to the chemical components of paints, a violation of the function of the biliary tract is formed, which leads to inflammation, the formation of scars and scars on the liver, and as a result, there is a blockage of the outflow of bile and massive tissue damage with an irreversible nature, and ultimately – cirrhosis of the liver. Less than 1% of the men surveyed used hair color products, while half of all women surveyed regularly used dyes.
