What is one key factor to consider when selecting a hair color for clients?

Selecting a hair color for clients fundamentally hinges on the client's natural hair color and skin tone. This is critical because matching hair color to a client’s natural features ensures a more flattering and harmonious look. The undertones in a person's skin can drastically affect how different hair colors appear. For instance, someone with warm undertones may look better in warmer hair colors, while cool undertones can often be complemented by cooler shades.

Furthermore, considering a client's natural hair color can help in determining the most achievable and realistic hair color options for them. This ensures that any coloring processes are performed with regard to the health of the hair, making it easier to achieve the desired look without causing undue damage.

In contrast, while current hair color trends can provide inspiration and influence choices, they should not be the sole consideration, as they do not account for individual client features. Similarly, hair texture and length, as well as the type of haircut, play a role in how a color might appear but are secondary to ensuring that the foundation—natural color and skin tone—is appropriate for the client.
