Guest guest Posted January 29, 2002 Report Share Posted January 29, 2002 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. Simple Solution: There was no association between semi-permanent or temporary hair dyes and bladder cancer. (See Safer Ways to Color Your Hair. " ) see below. 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 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. ___________ Permanent hair colors are the harshest for hair, and pose the most potential health risk. Whenever possible, choose temporary, semi-permanent, demi-permanent, and natural dyes. Simple Solution: Glossary of Dye Types * Permanent hair colors change the natural pigment found within your hair. * Demi-permanent color enriches color, adds shine, and blends gray. With its lower levels of hydrogen peroxide and artificial color molecules, this service has less structural impact on your hair then permanent color, and it gradually fades over a period of 4 to 6 weeks. * Semi-Permanent color stains your hair shaft and covers gray but fades after six to eight shampoos. Consider a natural color service or one that uses lower levels of hydrogen peroxide or developers, along with colors that have a lower dye lot. 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. If You Do Color ... Remember this advice for keeping colored hair as healthy as possible: * Protect and condition your hair and scalp regularly. * Don't stray far from your natural level and tone. Dramatic color changes require more upkeep, since outgrowth becomes very obvious very soon. (This reasoning also applies to texture services.) * Follow your stylist's recommendations for home-care regimen. * Color-enhancing shampoos do work, helping you hold on to your desired color between salon or at-home color treatmetns, so do try them out. * Be especially vigilant about protecting chemically treated and naturally colored hair from the sun. * The less you chemically process your hair, the more healthy it remains.

Guest guest Posted January 30, 2002 Report Share Posted January 30, 2002 Great. Thanks for that uplifting news.... me being a hairdresser for 20 years...so does that means I am 10 times at risk of getting Bladder cancer? What I don't understand is that the chemicals used are absorbed directly through the scalp, which, IMHO is why they are harmful.... so how are hairdressers at five times the risk if we don't even come into contact with it? I know you are thinking " you inhale it " but thats a different ball game again.... it's like saying that people who are exposed to cigarette smoke are at a higher risk than the smokers themselves..... I find that hard to believe! Anyway - to be honest - I don't care.... you have to die of something.... I enjoyed my years as a hairdresser, and every job has a risk factor of being exposed to something...
