What is the first step in performing a shampoo service?

The first step in performing a shampoo service is to wet the hair thoroughly. This is essential because it prepares the hair and scalp for the cleansing process. By thoroughly wetting the hair, you allow the shampoo to distribute evenly and create a lather, which helps to lift dirt and oils from both the hair and scalp. Additionally, wetting the hair opens up the cuticles, aiding in a more effective cleanse.

Starting the process with wet hair is crucial for ensuring that the shampoo can penetrate and clean effectively. It sets the stage for the subsequent steps in the shampoo service, such as applying the shampoo, massaging the scalp, and conditioning if necessary.
