Which of the following describes a consequence of not using warm water for shampooing?

Not using warm water for shampooing can lead to scalp irritation and discomfort because water that is too cold can constrict blood vessels and make it more difficult to clean the scalp thoroughly. Warm water, on the other hand, helps to open the pores and dissolve product buildup, which is essential for maintaining scalp health and comfort. Cold water may not adequately remove oils and dirt, leading to a less effective cleansing process. Therefore, the correct outcome of using cold water is that it can cause discomfort and potential irritation for the client, which may detract from their overall experience during a shampooing service.
