Hair straightening predates hair smoothing and was initially practiced on African hair to manage unruliness. This technique swiftly gained popularity. Hair smoothing, also known as the Brazilian keratin treatment, emerged in Brazil in 2003. Hair straightening encompasses both permanent and temporary methods, with the latter employing heat styling tools like hot irons or combs. The resulting straightness is transitory, reverting to its natural state after a wash. Some classify hair smoothing as a temporary subset of hair straightening. This professional procedure enhances hair manageability and aesthetics. It involves saturating the hair with a formaldehyde solution, followed by drying and employing a flat iron to set it in a straight configuration. Notably, the chemicals used in hair smoothing are milder than those in traditional straightening treatments.
