The protein treatment is specifically designed to repair and restore protein levels in the hair. Hair is primarily made up of a protein called keratin, and over time it can become damaged due to various factors such as heat styling, chemical treatments, and environmental stressors. A protein treatment helps to reinforce the hair's structure by adding protein back into the strands, which can improve strength, elasticity, and overall hair health.

In contrast, a moisturizing masque focuses on hydrating the hair rather than restoring protein. While it plays an essential role in keeping hair healthy and manageable, it does not target protein deficiencies. Color treatment refers to processes that change the hair color, enhancing its appearance but not specifically addressing the structural integrity related to protein. Likewise, a steam treatment primarily helps with moisture delivery by opening the hair cuticle to allow better absorption of hydrating ingredients, rather than focusing on protein restoration. Therefore, the protein treatment is recognized as the most effective solution for repairing and restoring the protein in the hair.
