What is one common effect of using a conditioner?

One common effect of using a conditioner is that it adds moisture and shine to the hair. Conditioners are formulated with various ingredients that help to nourish and hydrate the hair strands, which can lead to improved elasticity, softness, and overall shine. When hair is well-conditioned, it is more manageable and can better resist damage from environmental factors and styling tools.

The use of moisture in conditioners works by penetrating the hair shaft, making it less porous and helping to seal in hydration. This enhanced moisture balance not only gives hair a healthier appearance but also helps reduce frizz and improve texture, making hair look vibrant and full of life.

In contrast, the other options reference effects that are typically not associated with proper conditioning. For example, stranding hair, increasing brittleness, and permanently straightening are not benefits of conditioner use but rather possible results of misuse or inappropriate products.
