Meaning ❉ Protein Integrity refers to the enduring structural soundness of the hair’s keratin bonds, a core principle for healthy, resilient strands. For coils, curls, and waves, particularly within Black and mixed-heritage hair types, this means maintaining the natural strength and elasticity that allows for definition and length retention. Understanding protein integrity aids in building a comprehensive view of textured hair needs, moving beyond surface observations to a deeper appreciation of its internal architecture. Applying this knowledge allows for the thoughtful systematization of hair care practices, guiding decisions on when to introduce strengthening agents or prioritize hydration, much like a gentle calibration. This practical implementation supports hair in retaining its inherent structure, promoting consistent well-being and a gentle responsiveness to styling, ensuring each strand contributes to the hair’s collective vibrancy without strain.
