Using hair products with low pH typically leads to cuticle closing. The hair cuticle is the outermost layer of the hair shaft, and its state greatly influences hair health and appearance. When a product with low pH is applied, it causes the cuticle scales to flatten and close tightly.

This closure helps seal the hair shaft, leading to smoother and shinier hair. A lower pH can also enhance the hair’s ability to retain moisture, which is beneficial for enhancing overall hair texture and minimizing frizz. On the contrary, hair products with high pH might cause cuticles to swell and lift, leading to more porous hair, which can result in a rougher texture.

Products designed for specific results, such as color treatment or conditioning, often leverage pH levels strategically to achieve the desired outcome for hair health.
