The purpose of a shampoo and conditioning treatment is to cleanse the hair and scalp while providing moisture and protection. Shampoo works by removing dirt, oil, and product buildup from the hair and scalp, ensuring that the hair is clean. It often contains surfactants that help lift away these impurities without stripping the hair of its essential oils.

Conditioners follow up the cleansing process by restoring moisture, smoothing the hair cuticle, and providing protection against damage from heat styling, environmental factors, and more. Conditioning treatments also help improve the hair's overall manageability, texture, and appearance by replenishing hydration and essential nutrients.

The other options do not accurately reflect the comprehensive function of shampoo and conditioning treatments. Removing hair color, straightening curly hair, or merely enhancing shine focuses too narrowly on specific outcomes rather than the broader benefits of cleaning and moisturizing the hair and scalp that are essential for healthy hair care.
