What is the pH range of acidic hair products?

The pH range of acidic hair products typically falls between 4.0 and 6.0. This range is significant because acidic products can help to close the hair cuticle, leading to smoother, shinier hair. Acidic formulations are also beneficial for maintaining the overall health of the hair by helping to stabilize the pH level of the scalp and hair, which is naturally slightly acidic.

When hair products are within this acidic range, they can minimize damage from environmental factors and chemical treatments, enhancing the condition and appearance of the hair. The preferred acidity level aids in reducing frizz and improving manageability, making it an essential aspect of product formulation for individuals looking to maintain healthy hair.

In contrast, other ranges that fall outside of 4.0 to 6.0 would not provide the same benefits and may be more alkaline, which could lead to cuticle lifting and increased porosity, resulting in damage over time.
