Because so many people use hair dyes, scientists have tried to determine whether exposure to the chemicals in hair coloring products is associated with an increased risk of cancer in people.
Here, we will discuss what the research shows so that you can make choices that are comfortable for you.
Over 5,000 different chemicals are used in hair dye products, some of which are reported to be carcinogenic in animals. Thus, it can affect humans too.
Manufacturers, however, changed the components in dye products to eliminate some of these chemicals. It is not known whether some of the chemicals still used in hair dyes can cause cancer but given the widespread use these products, even a small increase in risk may have a considerable public health impact.
Most of the studies looking at whether hair dye products increase the risk of cancer have focused on the following type cancers:
Most studies of people exposed to hair dyes at work, such as hairdressers and barbers, have found a small but fairly consistent increased risk of bladder cancer. However, studies looking at people who have their hair dyed have not found a consistent increase in bladder cancer risk.
Leukemia and lymphoma
One study examined hair dye use among 769 patients with adult acute leukemia and 623 people without leukemia. It found that the risks of acute leukemia were higher among users both permanent and non permanent dyes than among those who had not used dyes, although the increases were not statistically significant.
Most studies looking at hair dye use and breast cancer have not found an increased risk. For other types of cancer, too few studies have been done to be able to draw any firm conclusions.
Although some studies have shown associations between hair dye use and the risk of developing or dying from specific cancers, these associations have not been seen in other studies.
However, it is still best to avoid these products. There's no harm in doing that besides it's better to be sure than to suffer in the near future. Being natural is still the best way possible to live a healthy life.
