What is a potential reason a physician might advise a client to use dry shampoo?

A physician may advise a client to use dry shampoo primarily for medical reasons affecting the scalp. Dry shampoo can be beneficial in certain scenarios where frequent washing with water and traditional shampoo could exacerbate a scalp condition. For instance, conditions like psoriasis or seborrheic dermatitis may benefit from reduced moisture and irritation that can accompany regular washing. Using dry shampoo can help manage oiliness while minimizing potential aggravation to sensitive scalps or allowing scalp conditions to heal without over-cleansing.

While convenience and other factors might play a role in someone choosing dry shampoo, the physician's guidance generally focuses on health and treatment considerations, making medical reasons the most fitting response.
