ITS IMPORTANT TO READ ABOUT THE VERY SERIOUS HEALTH RISKS: ';Stylists and clients often wear gas masks or other protective equipment and still may feel the ill effects of this potentially fatal gas. Brazilian treatment often contains high concentrations of formaldehyde, a cancer-causing chemical.';





';Brazilian Keratin Treatments aren't dangerous only to the stylist. It is theorized that repeated treatments will cause formaldehyde buildup in the hair, releasing formaldehyde fumes every time a patron blow dries or hot-irons her hair. There has been at least one documented death from the treatment.';





';Its major ingredient is formaldehyde, which is classified as a human carcinogen by the International Agency on research for Cancer, part of the World Health Organization. In short, it can cause cancer. The solution contains 10 times more than the 0.2 % that is determined to be safe by the Cosmetic Ingredient Review Expert Panel, a group of scientists and doctors who assess and set recommended safety standards for cosmetics ingredients.';


And its costs 400 to a 1000 US$ and it lasts about 4 months. Is it worth the risks?

no.. that is unnecessary. get the japanese hair straigtening, b/c it lasts longer (9 months to a year) and is about the same price as brazilian hair straigtening (which lasts about 4 months). however, i did read that brazilian hair straigtening believe it or not works best on color treated hair. consult your stylist about color treating your hair when you have japanese hair straigtening.
idk but Brazilian one is better
