What is the process used to rearrange overly curly hair into straightened hair?

The process of chemical hair relaxing is specifically designed to alter the structure of overly curly hair, transforming it into a straighter form. This is accomplished by applying a chemical relaxer that breaks down the protein bonds in the hair, allowing it to be reshaped. Once the relaxer is applied and processed, the hair becomes more manageable and can be styled straight.

This method is distinct from other techniques like permanent waving, which is intended to curl the hair rather than straighten it, and thermal styling, which refers to heat-based methods like flat ironing that temporarily straighten hair without altering its internal structure. Hair straightening can refer to a variety of techniques, including both chemical and heat-based methods, but in the context of the question about rearranging overly curly hair specifically, chemical hair relaxing is the most accurate term.
