What is the typical pH level range of healthy hair?

• A. 3.0 to 4.0
• B. 4.5 to 5.5
• C. 5.0 to 6.0
• D. 6.5 to 7.5

Answer: (B)

The typical pH level range of healthy hair is indeed between 4.5 to 5.5. This slightly acidic range is essential for maintaining the health of the cuticle, which is the outermost layer of the hair strand. When the hair is within this pH range, it helps to ensure that the cuticle lies flat, which not only contributes to the overall strength and resilience of the hair but also enhances its shine and smoothness. A pH level outside of this range can lead to various issues. For example, if the pH is too low (below 4.5), it can result in the hair becoming too tight and brittle, while a higher pH (above 5.5) can cause the cuticle to lift, leading to frizz, tangling, and damage. Maintaining a balanced pH is crucial in hair care products, as it helps preserve the natural properties of hair while also promoting optimal health and appearance. This understanding is vital for hairstylists when selecting shampoos, conditioners, and treatments for their clients.
