There has been a whole lot of media attention recently about a possible connection between hair dye and cancer.
The International Agency on Research on Cancer, a component of the World Health Organization, said recently that there does indeed appear to be a connection between hair dyes and bladder cancer. However, the risk appears to be minimal and the best risk appears to be among male barbers and hair care professionals that are exposed to large quantities of hair dyes on a daily basis. The best risk appears to be in utilizing permanent dark-colored hair dyes.
While today's hair dyes are rather safe to use, there's still some concern for people who used hair dyes before 1980. A study from Yale University found that women who began using dark hair dye prior to 1980 had an increased chance of non-Hodgkin's lymphoma. However, women who began dying their hair after 1980 didn't reveal this increased risk.
In 1980 the U.S. banned the use of hair dye components derived from coal tar. Those ingredients, such as HC Blue 1, were shown to be carcinogenic. (It should be noted that while the U.S. prohibited the use of those ingredients, they still might be allowed to use in different countries, particularly smaller, developing countries.)
Therefore, people aged 40 and older who have dyed their hair for several years and are worried about cancer, should consult their general practitioner or oncologist. There's always a risk that toxins out of a hair dye could be absorbed in the body.
Some people today believe using hair dye conveys some other health dangers. By way of instance, bleaching one's hair can burn the scalp and hair and in extreme cases may cause skin infections.
Moreover, studies have found that women who color their hair for 20 years or more may almost double their risk for rheumatoid arthritis. It's not clear if this is because they began with hair dyes made before 1980.
Pregnant or breastfeeding women shouldn't dye their hair since their unborn children are 10 times more likely to get cancer.
Lots of men and women report allergic reactions to hair dyes. The itchiness might lead to sores. Some might also have difficulty breathing due to an allergic reaction to the dye's ingredients.
People who prefer to dye their hair unusual colors, such as blue or pink, ought to bear in mind that these dyes contain lead acetate and coal tar, each of which can damage the body's immune and reproductive systems.
Most products counsel consumers to try out a skin test a couple of days prior to applying the dyes. If any adverse reaction is detected, do not use the dye and consult a physician, depending on the conditions.
So as to prevent most dangers, experts recommend avoiding dark and permanent hair dyes. Rather use natural hair dyes which use henna or herbal/vegetable dyes. Do not mix hair dye products.
In reading this list of risks, bear in mind that in general hair dyes are extremely safe. By following package instructions, it is possible to have beautiful hair and a healthy body.
