Which chemical process is used to make hair more manageable and reduce frizz?

Hair relaxing is a chemical process specifically designed to make hair more manageable by reducing frizz and loosening the natural curl pattern. This method involves the application of a relaxing agent that breaks down the protein structure of the hair, allowing it to be reshaped into a straighter form. As a result, hair becomes easier to style, and the overall texture is smoother, which is particularly beneficial for those with thick, coarse, or curly hair that is prone to frizz.

In the context of the other options, hair coloring is primarily focused on changing the hair’s color and does not directly affect texture or manageability. Hair perming involves curling the hair, which is the opposite of what individuals seeking frizz reduction would want. Hair straightening, while it can temporarily smooth and flatten hair, typically involves using heat or other methods rather than a chemical process aimed at modifying the hair’s natural structure like relaxing agents do. Therefore, the most suitable choice for reducing frizz and improving manageability is hair relaxing.
