Well, depending on which low-poo you use, it can actually be more drying than a sulfate. Some report a more stripped feeling when using a low-poo as compared to a sulfate wash, it just depends on what product you're using and how your hair reacts. Sulfates aren't the devil, they just need to be dealt with carefully.
