The role of a scalp treatment in hair care is primarily to help cleanse and nourish the scalp. A healthy scalp is essential for maintaining strong and vibrant hair. Scalp treatments generally involve the use of specialized products designed to remove excess sebum, dead skin cells, and product buildup, which can otherwise lead to issues such as dandruff, irritation, or hair loss. Additionally, these treatments often include ingredients that provide nutrients and hydration to the scalp, fostering a more conducive environment for hair growth.

While other options mention important aspects of hair care, they do not accurately reflect the specific function of scalp treatments. For instance, adding color to hair relates to hair dye processes rather than scalp health. Similarly, changing the hair's texture pertains to chemical treatments or styling methods and does not involve direct care of the scalp. Protecting hair from heat styling is also crucial, but it is typically achieved through the use of heat protectant products, not scalp treatments.
