Conditioners play a crucial role in hair care primarily by restoring moisture and improving manageability. Hair can become dry and frizzy due to various factors such as environmental conditions, heat styling, and chemical treatments. Conditioners are formulated with ingredients that help to hydrate the hair, providing essential moisture that is lost during these processes.

By replenishing moisture, conditioners smooth the hair cuticle, which enhances its shine and makes it easier to detangle. This results in hair that is softer and more manageable, reducing breakage and allowing for easier styling. Moreover, conditioners can help prevent damage caused by environmental stressors, maintaining the overall health of the hair.

While the other options mention aspects that are important in hair care, such as strengthening roots and promoting growth, these are not the primary functions of conditioners. Instead, the main focus of conditioners is to enhance moisture levels and manageability, making option B the best choice.
