Why is gum used to shape hairstyles?

The barber wants to shape the hairstyle; Usually after drying the hair, spray on the hair that has dried 1 foam-like substance. They called it the gum shaping. After spraying is finished, the shape of the hair is fixed, it is not disturbed by the wind, while ensuring a long time without changing the style.

Hair spray is a macromolecular compound that has undergone chemical processing. Its molecular amount is up to several hundred thousand or even millions . In which carbon atoms have tens of thousands, they link together into long chains. On that chain, there are also hydrogen, oxygen and nitrogen atoms. These atoms are adjacent to each other, becoming a highly durable material. If the middle of the chain with the chain is linked by some atom or chemical origin, it will become a linked material in the form of a grid. Even if the material is heated, it is not soft or deformed.

Hair spray is mainly due to polymer ethylene, pirone, alkanes, hydrocarbons (0.5% ~ 4%) of hydrocarbonpropyl fibers and hydrocarbonsrimethyl amine, benzene 0.5% together to form. It is then added to the mixture on 15% alcohol and deionized water (60% -65%), a very small amount of plasticizer, water and aromatherapy essence. For convenient use, there is an additional spray (15%) in the gum, when spraying on hair, dissolved substances which easily evaporate. High molecular weight compounds dissolved in water and the positive ions of albumin form on the surface of the hair 1 polymeric membrane holds the shape of the hair and can be washed easily.

Now hair-forming drugs are getting more and more abundant. Except for hair spray, there are also shaped water; In addition to the effect of shaping the hair, it also works to nourish the hair, keeping the black hair soft and silky.
