What is the first step in a standard shampoo procedure?

The first step in a standard shampoo procedure is wetting the hair thoroughly. This initial action is crucial because it prepares the hair and scalp for the application of shampoo, allowing it to distribute more evenly and effectively. Wetting the hair helps to loosen any dirt, oils, and product buildup, making it easier to cleanse the hair during the shampooing process.

Starting with thoroughly wet hair also helps to ensure that the shampoo can lather properly, as it requires moisture to activate its cleansing agents. This step is foundational to any effective hair cleansing routine, setting the stage for the subsequent steps, such as applying shampoo, massaging the scalp, and rinsing. Each of those steps is important, but they follow after the hair has been adequately wet.
