What should clients be informed about when applying a colored filler?

Informing clients not to be alarmed by an unusual color during the application of a colored filler is crucial for setting realistic expectations. When a filler is applied, it often appears different from the final color due to the underlying hair tones and the nature of the filler itself. This temporary, unusual appearance is a part of the process toward achieving the desired end result. Clients may see shades that seem unexpected, which can be unsettling if they aren't prepared for it.

Understanding this aspect helps clients remain calm and confident in the process, leading to an overall more positive experience while allowing the stylist to work effectively. This reassurance helps to build trust in the stylist's expertise and maintains a good client-stylist relationship. Providing this information also helps mitigate any potential anxiety about the hair color transformation.
