Hair straightening is a hair styling technique used since the 1890s involving the flattening and straightening of hair in order to give it a smooth, streamlined, and ‘sleek’ appearance. It became very popular among black males and females of all races, during the 1950s, the former group because black men wanted to have the very popular and stylish “greaser” look, either that or wearing Afros. It is accomplished using a hair iron or hot comb, chemical relaxers, Japanese hair straightening, or Brazilian hair straightening. In addition, some shampoos, conditioners, and hair gels can help to make hair temporarily straight. The process is often called “rebonding” in some countries from Southeast Asia (e.g. Singapore, Malaysia and Philippines). The term “rebonding” was first used by REDS Hairdressing from Singapore in the late 1980s, which slowly spread to the rest of the region. If done often, flat irons and chemicals can be damaging to hair. Excessive straightening often results in split ends. However, heat protectant sprays can decrease the damage.
