Silkience self adjusting shampoo! Not only does it know to wash out where it's oily, it also adds moisture to here it's dry. Here, look at our poorly pixelated computer computer demonstration of oily vs dry hair, and please don't laugh. We only have 85KB of ram on this thing. *Flips hair* Anyway, I look fantastic. Thanks to Silkience - self-adjusting shampoo!
