To Dye or Not To Dye? Permanent Hair Dyes

"If you use permanent hair dyes at least once a month you should know about a 2001 study from researchers at the University of Southern California that analyzed the association between hair dying activity and bladder cancer.
There was no association between semi-permanent or temporary hair dyes and bladder cancer. (See Safer Ways to Color Your Hair.)
While the study was not a clinical cancer trial, it did make a determination of those who are at highest risk from use of permanent dyes:
* Women who use permanent, hair dyes once a month for 1 year or longer have twice the risk of bladder cancer.
* Women who use permanent hair dyes for 15 or more years at least monthly have three times the risk of bladder cancer using permanent dyes for 15 or more years when the dyes are used monthly or more frequently.
* Those who have worked as hair dressers or barbers for 10 years or more have five times the risk of bladder cancer.
The researchers note that the exposure of concern is to a family of chemicals called Arylamines, an ingredient in many oxidative hair dyes, which is a known risk factor for bladder cancer and found to cause cancer in experimental animals.
The study was considered of enough concern in Europe that the European Commission, a body that drafts legislation for the European Union, has changed their policy to demand information from manufacturers about ingredients contained in hair dyes. The United States does not required manufacturers to file data on ingredients or report cosmetic-related injuries.
Darker hair dyes cause higher risk because of the increased number of chemicals."
As an alternative...Natural and Herbal Color Rinses
Certified organic henna and plant materials can also color your hair, but with a more gentle and natural approach, since they contain no synthetic chemicals, preservatives, or harsh oxidizing chemicals, such as ammonia. These pure vegetable products do not alter the structure or natural color of your hair and actually condition your hair while imparting color and sheen. No matter what you have heard, these products have come a long way.
You can create a wide variety of plant pigment color rinses yourself. These concoctions do not create radical hair color change, but instead accentuate your hair's natural tone and shine. If your hair is less than 15 percent gray, some plants will disguise the gray. In these cases, the product actually stains your hair, although very subtly. Cumulative usage creates longer-lasting, slightly more intense results. You can repeat the application as often as desired, depending on the color level you prefer.
You can get varying tones from red to black with henna and/or indigo. You can get golden tones to strawberry blond with henna and cassia.
