You’ve probably seen her at some point: the girl who casually saunters past you on a busy street and gets everybody’s heads turning. It’s not because she’s a movie star or because she has movie star looks, and it’s not because she is wearing an expensive designer dress, or flamboyant hair accessories.

Greasy, limp and lifeless—if this is the hair you wake up to every morning, you probably have oily hair. All hair types present their own set of challenges, and oily hair, though it requires daily cleansing, is one of the more manageable types because it’s not dry.

Our hair is such a basic part of our lives that oftentimes, we neglect its overall health. We go from long to short, straight to wavy, brunette to blonde, and from one trendy hair accessory to another. It helps define our individuality, and changing it up every now and then is a great mood booster for any girl. The heat of the sun, polluted air, even our unhealthy appetites affect our hair.
