A shampoo is basically a solution of a detergent
containing suitable additives for other benefits such as hair conditioning
enhancement, lubrication, medication etc.
Now-a-days many synthetic, herbal, medicated and non
medicated shampoos are available in the market but popularity
of herbal shampoo among consumers is on rise because
of their belief that these products being of natural origin are
safe and free from side effects (Manikar and Jolly, 2001).
