What is the main function of a leave-in conditioner?

The primary function of a leave-in conditioner is to provide hydration and protection to the hair throughout the day. Leave-in conditioners are formulated to be lightweight and easy to apply, allowing the product to remain in the hair after washing without needing to be rinsed out. This helps maintain moisture levels, which is crucial for preventing dryness and damage, particularly for individuals with textured or chemically treated hair.

In addition to hydration, leave-in conditioners often contain ingredients that protect hair from environmental stressors, heat styling, and UV rays. By using a leave-in conditioner, hairstylists and clients can keep the hair manageable, promote overall health, and enhance the hair's natural shine throughout the day. This is particularly beneficial for those who may not have the time to engage in lengthy hair care routines but still wish to maintain healthy hair.

Overall, leave-in conditioners serve as a practical and versatile product that supports daily hair health, making option B the most accurate choice.
