What are sodium hydroxide relaxers commonly referred to as?

Sodium hydroxide relaxers are most accurately referred to as alkaline relaxers. These relaxers work by breaking down the protein structure of the hair through a high pH level, which allows for the permanent alteration of the hair's texture. Sodium hydroxide, being a strong alkaline agent, penetrates the hair shaft and relaxes tight curls or waves.

Understanding the terminology is crucial. While options like "metal relaxers" refer to a different category of products that use metallic salts to straighten hair, and "ammonium thioglycolate relaxers" denote a different type of chemical formulation that is more suited for soft curl and wave styles, “alkaline relaxers” correctly encompasses the nature of sodium hydroxide relaxers. These products create a highly alkaline environment which is essential in loosening the hair's curl pattern effectively.

In summary, the choice of "alkaline relaxers" reflects the chemical engagement of sodium hydroxide in performing hair straightening, aligning with the chemical principles involved in the process.
