Just got this. This is wild, but, sadly, not particularly astounding to hear...and, sadly, not a joke * Check Your Shampoo: Check the ingredients listed on your shampoo bottle, and see if they have this substance by the name of Sodium Laureth Sulfate, or simply SLS. This substance is found in most shampoos, and the manufactures use it because it produces a lot of foam and it is cheap. BUT the fact is that SLS is used to scrub garage floors, and it is very strong. It is also proven that it can cause cancer in the long run, and this is no joke. I went home and checked my shampoo (Vidal Sasoon), it doesn't contain it; however, others such as Vo5, Palmolive, Paul Mitchell, the new Hemp shampoo, etc., contains this substance. So I called one company, and I told 20 them their product contains a substance that will cause people to have cancer. They said "Yeah, we knew about it but there is nothing we can do about it20 because we need that substance to produce foam. By the way Colgate toothpaste also contains the same substance to produce the "bubbles." They said they are going to send me some info. Research has shown that in the 1980s, the chance of getting cancer is 1 out of 8000 and now, in the 1990s, the chances of getting cancer is 1 out of 3, which is very serious. So I hope that you will take this seriously and pass this on to all the people you know, and hopefully, we can reduce the cancer risk.
