it all started a year ago with a bald spot and not knowing what caused it but I realized I was getting a rash on the side of my head but stubbornly I kept using it and then 4 more spots showed up! I was horrified! I didn't know what to do! I had to figure out what was causing it then I came up with a conclusion that I started using hair dye for a year and now it's causing this horrific side effects! To make long story short, I stopped using the chemical ridden hair dye such as Clairol and other commercial brand, I instead purchased the all natural hypoallergenic one and not it's been about 7 months I stopped using the stinking chemical hair dye and all the bald spots are back to normal with my hair! I want to let everyone know that the FDA or whoever is in charge of making warning labels for hair dye is more than likely concealing the facts about hair dye causing hair loss all due to greed and making money off of consumers. Imagine if they place that warning label as, "hair dye can cause hair loss!" Who would buy it? Please be careful and don't use the chemical hair dye and get the all natural ones if you must use hair dye at all.
