Identifying protein deficiency in hair involves recognizing specific changes in its structure and behavior. These changes may manifest as increased breakage, a loss of elasticity, or a gummy texture when wet. For example, strands may stretch excessively without returning to their original length, indicating a weakened protein framework.
Maintaining adequate protein levels within the hair shaft is crucial for its strength, resilience, and overall health. Protein provides the building blocks necessary to repair damage and protect against environmental stressors. Historically, treatments focusing on protein have been employed to counteract the effects of chemical processing, heat styling, and mechanical manipulation.
