Dry shampoo is a cosmetic product with a specific formula that removes dirt, excess sebum and odor from the hair and scalp without the use of water.
Washing with this innovative shampoo consists of two easy steps: evenly applying, with massage movements, the appropriate amount of the product on the scalp and gently combing the hair a few minutes later.
The earliest historical evidence for the existence of such shampoos dates from the late 15th century when the inhabitants of Asia used clay powder to freshen up their hairs.
A few more centuries passed before the advent of the first commercial dry shampoo. It was released on the market in 1940 in New Jersey and was entitled "Minipoo". The product quickly became popular thanks to its extensive advertising campaign highlighting its advantages over liquid shampoos.
The formula that doesn’t require washout allows cleaning of the hair in the absence of water, time, physical ability or a suitable ambient temperature. Besides preventing the danger of getting sick in cold weather, dry shampoo does not cause tearing and eye irritation. At the same time, the absence of a final rinse in the procedure preserves longer the hairstyle, the color of dyed hair and the shape of the curls. In spite of all the advantages, experts are of the opinion that the dry shampoo should not be used daily, but only when the situation really requires it.
Initially, dry shampoos contained only about 2-3 ingredients with absorbing properties, while nowadays they are enriched with nutrients, such as vegetable oils and proteins. There are available as powders or a sprays, with or without fragrance, as well as in different varieties according to the type and color of the hair.
Besides its main application, today the dry shampoo has a few more unusual ones. Some people use it to give more volume to their hair, to fix it in the desired shape or to conceal their dark hair roots. Others want to highlight their eyebrows or reduce the sweating of their underarms and palms. And some people use it to clean stains on their home textiles or to deodorize shoes.
