Which salon service requires a consultation before proceeding?

Hair coloring requires a consultation before proceeding due to the complexities and potential risks associated with the service. During the consultation, the cosmetologist assesses the client's hair condition, discusses the desired outcome, and addresses any allergies or sensitivities to hair color products. This step is vital to ensure the health of the client's hair and scalp, as well as to achieve the desired color results. It allows the professional to recommend suitable products and techniques that align with the client's unique hair type and goals, ultimately leading to a more satisfactory outcome.

While hair washing, scalp treatments, and hair cutting are important services, they do not typically require the same level of consultation regarding potential risks or specific client preferences as hair coloring does. Hair washing is a routine service, scalp treatments might involve assessment but aren't as complex, and hair cutting, while it can benefit from discussions about style, generally doesn’t involve the same level of risk management as coloring.
