Using products with a high pH can have a significant impact on the hair's structure. A high pH typically leads to an alkaline environment, which causes the cuticle—the outer protective layer of the hair—to lift. When the cuticle is raised, it can make the hair more porous and susceptible to damage, moisture loss, and frizz. This lifted cuticle can also affect how well hair retains color and moisture, sometimes leading to dullness or a lack of shine. This is particularly relevant when considering how various hair treatments and products interact with hair; understanding pH levels helps professionals choose the appropriate products for different hair types and conditions.

In contrast, options suggesting that high pH products enhance hair color or add moisture would not be accurate, as a lifted cuticle typically makes it harder for hair to retain moisture and maintain vibrant color. Similarly, a softer hair texture would not usually result from high pH products, as these can lead to roughness and increased porosity instead.
