Sulfates the new BPA?

The latest trend in hair products is sulfate-free shampoos and conditioners. Although, most conditioners don't use sulfates so I'm not sure why you need a sulfate-free one. I wondered if this was just another marketing scheme to scare people into buying new products-or if sulfates were the new BPA (you know those bad water bottles of last year)? After a little research and tweeting with my friends at The Beauty Brains, I've come to the conclusion that it's just HYPE. Why? Sulfates are what make our shampoo's (and body washes) foam up so you can get that nice lather. Also, sulfates break down the dirt and oil in the hair. That's all they are. They don't strip the color out any faster than their sulfate-free counterparts. However, sulfate-free are less drying so if you have super dry skin/scalp you might benefit from them. To read more on what kind of sulfates are in shampoo's read here and here. I think both these explain it very well. For those who think they cause cancer: wrong (they might just give you "the runs" if ingested). Read here for more on this. So my dear readers what do you think?
