Acid-balanced shampoos and normalizing lotions play a crucial role in the hair relaxation process when used alongside hydroxide hair relaxers. They create an acid-alkali neutralization reaction. Hydroxide relaxers are alkaline, which means they raise the pH of the hair's structure, making it more susceptible to chemical change. When acid-balanced products are applied, they contain ingredients that help to lower the pH and neutralize the alkalinity of the relaxer. This is important because it allows the hair to return to a more neutral state, preventing damage and ensuring that the hair maintains its integrity after the chemical process.

Additionally, this neutralization process creates a better environment for the hair to recover and retain moisture, ultimately leading to smoother and healthier hair results. Therefore, the role of acid-balanced shampoos and normalizing lotions in creating a balanced pH environment is essential for achieving optimal results during and after the use of hydroxide hair relaxers.
