What role does pH play in hair care products?

pH plays a crucial role in hair care products primarily because it affects the hair’s moisture balance and overall health. Hair is composed of a protein called keratin, and the structure of keratin can be influenced by the pH level of the products used.

When the pH of a product is balanced, typically ranging from 4.5 to 5.5, it helps maintain the natural acidity of the scalp and hair. This balance is essential for keeping the hair cuticle closed, which in turn helps retain moisture, enhances shine, and protects against damage. Conversely, products with a high pH can raise the cuticle, leading to moisture loss, frizziness, and increased susceptibility to damage from environmental factors.

Understanding the importance of pH in hair care enables professionals to choose the right products for their clients, ensuring optimal results in terms of hair health, texture, and moisture retention.
