Question: 1 / 400

What is the natural pH level of hair?

Between 3.5 and 4.5

Between 4.5 and 5.5

The natural pH level of hair typically falls between 4.5 and 5.5. This acidic range is important for maintaining the health and integrity of the hair structure. The slightly acidic pH helps to keep the cuticle layer of the hair closed, which protects the inner layers and prevents damage such as dryness, brittleness, and breakage. An environment within this pH range also supports the natural oils produced by the scalp, which can nourish and maintain the hair's moisture balance.

When hair is exposed to products or environmental factors that significantly raise its pH beyond this range, the cuticle can lift, leading to increased porosity and a higher risk of damage from heat styling, chemical treatments, or environmental stressors. Conversely, using hair care products that are too acidic can potentially weigh the hair down or lead to excessive oiliness.

By understanding the natural pH level of hair, barbers and stylists can make informed decisions about the types of products they use and recommend to clients, ensuring optimal hair health and appearance.
