What is the primary function of a conditioner?

The primary function of a conditioner is to moisturize and improve the texture of hair. Conditioners are specifically formulated with ingredients that help to hydrate the hair strands, making them softer and more manageable. They work by replenishing moisture lost during the washing process, smoothing the hair cuticle, and reducing frizz.

Conditioners also help to detangle hair, making it easier to comb through, which can reduce breakage and damage. By improving the overall texture, conditioners enhance the hair's appearance, making it look shinier and healthier. This moisturizing property is essential for maintaining the integrity of the hair, especially for those with dry, damaged, or chemically treated hair.

In contrast, other options do not align with the primary purpose of a conditioner. Adding color is typically the function of hair dyes and color treatments, while cleansing the scalp is the role of shampoos. Providing hold for hairstyles is characteristic of styling products like gels or hairsprays. Thus, the focus of a conditioner on hydration and texture improvement is what distinguishes it and makes option B the correct choice.
