Using high pH products on hair strips moisture from the hair, which is critical for maintaining healthy strands. High pH formulas, often found in certain shampoos, highlights, and chemical treatments, can disrupt the hair's natural acidic balance. This disruption can lead to the cuticle layer of the hair becoming raised, allowing moisture to escape and making the hair more porous. When moisture is lost, hair can become dry, brittle, and prone to breakage, ultimately leading to a dull appearance and increased fragility. Therefore, it’s essential to understand the pH levels of products used in hair care and their impact on hair health, particularly in terms of moisture retention.
