What is the purpose of protein conditioners in hair care?

The primary purpose of protein conditioners in hair care is to strengthen and reconstruct the hair. These conditioners are formulated with hydrolyzed proteins, which are smaller versions of the proteins found in hair. When applied to the hair, they can penetrate the hair shaft, helping to repair damage from chemical processes, heat styling, and environmental factors. By reinforcing the hair's structure, protein conditioners contribute to improved elasticity and resilience, making hair less prone to breakage and split ends.

In contrast, adding fragrance, artificially coloring hair, or enhancing shine are not the main objectives of protein conditioners. While some conditioners may incorporate these additional benefits, the essential function of protein conditioners is focused on hair strength and health.
