What is the typical pH range for hair conditioners?

Hair conditioners are typically formulated to have a pH range that is slightly acidic, which aligns with the natural pH of human hair and scalp. The ideal pH range for hair conditioners is from about 4.5 to 6.0. This slightly acidic pH helps to smooth the hair cuticle, reduce frizz, and enhance shine, as well as maintain the overall health of the hair and scalp. By keeping the conditioner within this pH range, it helps to prevent damage to the hair and promotes better moisture retention, which is vital for maintaining healthy hair.

Conditioners with a pH closer to neutral or alkaline (like the ranges provided in other options) could cause the hair cuticle to lift, leading to increased porosity and potential damage. Therefore, the choice indicating a pH range of 3.0 to 5.5 is aligned with these benefits, ensuring that the products used help to restore and maintain the integrity of the hair.
