The hair dye is one of the most popular beauty products among women who use it to cover gray hair or to give a different touch of color to their manes, however, this hair color gives you cancer probably.
The dyes can be permanent, semi-permanent and temporary, the first being the most requested among women, since they are 80% of all dyes that are currently marketed.
Those permanent ones consist of two products: “intermediates” (chemical substances called aromatic amines) and “couplers” which, combined with hydrogen peroxide, react and form the color molecules that paint the hair.
Generally, the darkest colors are those with the highest amounts of “intermediates.” While semi-permanent and temporary dyes do not need oxidation and paint the hair directly.
That is why this have drawn the attention of numerous scientists who have carried out multiple studies that hair dye causes cancer to determine if this product is a risk factor for cancer in people.
An investigation, based on information from four small studies, revealed that women who had used hair dyes for a long period of time had a 30% higher risk of suffering from non-Hodgkin’s lymphoma.
Another study, conducted on 769 patients with acute leukemia and 623 healthy people, found that you can get cancer from dying your hair, permanent and non-permanent, for more than 15 years.
This disease has caused such concern that numerous investigations have been conducted in this regard, according to the NCI, with conflicting results, since while some found no evidence, others found a risk factor.
