Modern shampoos contain many ingredients designed to effectively cleanse the hair and scalp while also producing the luster and shine that many consumers crave. Shampoos work to weaken the forces that bind dirt and residue to the hair as well as remove buildup of hair products and sebum [1].

However, accumulation of excess sebum can give the hair an oily appearance, which may be undesirable, particularly in individuals with straight hair who experience rapid movement of sebum from the root to tips [3]. Sebum is also a potent attractant of dirt, dust, and other pollutants from the environment [2]. C. Aguh, .
