Should You Be Using a Sulfate-Free Shampoo?

Sulfate-free: You've seen the term everywhere, on label after label at the drugstore, in magazine ads, and even in a few TV commercials.
But what does it really mean?
And should you be concerned that the shampoo in your shower isn't part of this popular crowd?
Here's exactly what you need to know.
It all depends on your hair type; those with parched or color-treated hair may benefit from using a gentler cleansing choice to prevent their hair from feeling super dry, while those who have greasier strands will probably find that they need to use sulfates to truly feel like their hair is clean.
