What is the best way to find the right foundation shade for a client?

Finding the right foundation shade for a client is crucial for achieving a natural look that seamlessly blends with their skin tone. Applying foundation to the jawline is the best method because this area serves as a transitional zone between the face and neck, allowing a cosmetologist to assess color matching effectively.

When foundation is applied to the jawline, the client can better see how the shade looks both on their face and in combination with their neck. This helps in determining whether the undertones of the foundation match their overall complexion. A good foundation shade will not only blend in with the skin on the jawline but should also smoothly transition into the neck without leaving a noticeable line of demarcation.

Other application areas, such as the forehead or cheeks, might not provide the most accurate depiction of how the foundation will look with the entire face and neck, as these areas can be influenced by factors like lighting and natural shadowing. Applying it to the neck can give a sense of matching but may not reflect how it looks in the context of the entire face. Thus, applying foundation to the jawline combines responsiveness to both the facial and neck skin tones, making it the optimal choice for finding the right shade.
