Before performing a chemical service, it's crucial to assess the client's hair types and scalp condition. This is because different hair types—such as straight, wavy, curly, or coily—react differently to chemical treatments. For example, fine hair may be more susceptible to damage than coarse hair. Understanding the scalp condition is equally important, as a sensitive or irritated scalp may lead to adverse reactions during a chemical service, potentially causing discomfort or injury.

By evaluating these factors, a stylist can select the appropriate products and techniques that will minimize the risk of damage while achieving the desired results. This assessment helps ensure a safe and effective service tailored to each individual's unique hair and scalp needs. In contrast, while understanding a client's hairstyle preference, the weather conditions, or their favorite products may be important for other reasons, they do not directly impact the safety and effectiveness of the chemical service like the assessment of hair types and scalp condition does.
