Chemical relaxers are hair products designed to straighten curly or wavy hair by breaking down the protein structure of the hair. They contain strong chemicals, such as sodium hydroxide or ammonium thioglycolate, which alter the hair's natural texture. This process can make hair more manageable and easier to style, but it can also lead to damage if not used properly. The application of chemical relaxers typically involves sectioning the hair and applying the product evenly. After a specified time, the relaxer is rinsed out, and a neutralizing shampoo is used to stop the chemical process. Regular maintenance and care are essential to keep the hair healthy after using chemical relaxers.
