Which condition is more likely if you frequently use a high pH shampoo?

Using a high pH shampoo can lead to dry and brittle hair because such shampoos are often more alkaline than the natural pH of hair and scalp, which is typically around 4.5 to 5.5. This elevated pH level can cause the hair cuticle, the outer protective layer, to lift or open up. When this occurs, moisture can escape from the hair shaft, leading to increased dryness. Additionally, the cuticle may become damaged, resulting in brittleness and a lack of elasticity.

Frequent use of high pH shampoos can strip natural oils from the hair and scalp, further contributing to the issue of dryness and increasing the risk of breakage. On the other hand, conditions such as being healthy, moisturized, or shiny and smooth would not typically result from the ongoing use of products that disrupt the natural pH balance of the hair. Instead, proper pH-balanced shampoos help maintain moisture and hair health.
