List the first step of a basic shampooing technique.

The first step of a basic shampooing technique is to wet the hair. This step is crucial because it prepares the hair and scalp for the shampoo application. Wetting the hair allows the shampoo to spread more easily and effectively, leading to better distribution of the product during the cleaning process. Additionally, wet hair helps to loosen dirt, oil, and buildup, making it easier for the shampoo to cleanse the scalp and strands thoroughly. Starting with this step ensures that the hair and scalp can receive the maximum benefits from the following steps, such as applying shampoo and rinsing.
