6 Facts You Probably Didn’t Know About Shampoo

Bar soap

Shampoos give your hair a well-needed clean. But before the advent of shampoo, people use bar soap to wash their hair. However, bar soaps are incompatible with hard water and can be irritating to the eyes.

Hair washing wasn’t necessary

The practice of daily shampooing wasn’t a norm in the U.S. during the 19th century. In fact, women would only shampoo their hair once every 6 weeks. During this time, shampoo wasn’t available in the market so people were using it sparingly. Shampoo was only used by professional stylists.


The word shampoo was derived from the Hindi word “champu”, which means to massage or press. Sake Dean Mahomed, a Bengali entrepreneur, opened a bathhouse in the English countryside after experiencing the Indian practice of champu. He started offering services that mimics champu, which he then referred to as shampooing.

Shampoos expire too

Shampoos should only be kept for a maximum of 3 years. Opened bottles, on the other hand, should be disposed off after 18 months. While expired shampoos do not actually harm your scalp or hair, it becomes less effective and won’t perform as intended. So how do you know if the shampoo is expired? It usually appears runny. You can also tell by the smell.

Dry shampoo

Dry shampoo is designed to rid your scalp and hair of oil, debris and odor without washing your hair. Originally, it was formulated for the sick or elderly who are having a hard time washing their hair.

It can be used as an alternative for shaving cream

Forgot to bring your shaving cream during a trip? No problem. You can use shampoo as an alternative. Shampoo lathers quite well and will also thoroughly cleanse your skin. Just wet the area of the skin you are going to shave. Lather up some shampoo and shave away.
