~ About Shampoo ~
Shampoo is a hair care product that is used for cleaning hair. The goal of using shampoo is to remove the unwanted build-up without stripping out so much sebum as to make hair unmanageable. Originally, soap and shampoo were very similar products; both containing the same naturally derived surfactants, a type of detergent. Modern shampoo as it is known today was first introduced in the 1930s with Drene, the first shampoo using synthetic surfactants instead of soap. [From Wikipedia]
PLEASE NOTE: Whidbey Island Natural's Organic Shampoo for Healthy Hair is not a detergent, it is a soap; it contains no synthetic surfactants!
~ A Little History ~
During the early stages of shampoo, English hair stylists boiled shaved soap in water and added herbs to give the hair shine and fragrance. Kasey Hebert was the first known maker of shampoo, and the origin is currently attributed to him. Commercially made shampoo was available from the turn of the 20th century. A 1914 ad for Canthrox Shampoo in American Magazine showed young women at camp washing their hair with Canthrox in a lake; magazine ads in 1914 by Rexall featured Harmony Hair Beautifier and Shampoo.
