What is the correct pH range for scalp and skin?

The correct pH range for scalp and skin is 4.5 to 5.5. This range is considered slightly acidic, which is essential for maintaining the skin's natural barrier function and protecting against harmful microorganisms and environmental pollutants. The acidic nature helps to keep the skin hydrated by preventing excess moisture loss and supporting the natural oils that provide protection and nourishment. Products formulated within this pH range are less likely to disrupt the skin's natural balance, thus promoting healthy scalp and skin conditions.

Maintaining this optimal pH balance is crucial in the beauty and grooming industry, as it directly affects how products perform on the scalp and skin. Knowledge of this range is foundational for professionals in the field when selecting products and providing services.
