What type of product is commonly used for chemical straightening?

1. Shampoo

2. Relaxer

3. Conditioner

4. Hair gel

The correct answer is: Relaxer

The product commonly used for chemical straightening is a relaxer. Relaxers are specifically formulated to alter the structure of curly or wavy hair, making it straight. They contain strong chemicals, such as lye or no-lye formulations, which break down the disulfide bonds in the hair. This process allows the hair to be reshaped and made straighter, providing a long-lasting solution for individuals who desire smooth, straight hair. Other options do not fulfill the purpose of chemical straightening. Shampoos are primarily used for cleansing the hair and scalp, while conditioners are intended to moisturize and replenish hair after cleansing. Hair gel is a styling product that provides hold and definition but does not alter the hair’s natural texture or structure. Thus, relaxers are the appropriate choice for achieving chemically straightened hair.
