When checking for color accuracy on hair, what should a barber do?

When assessing color accuracy on hair, examining under different lighting is crucial because lighting conditions can significantly affect how colors are perceived. Natural sunlight, fluorescent lighting, and incandescent bulbs all influence the appearance of hair color differently. By checking the color in various lighting environments, a barber can better determine the true shade and any inconsistencies that might not be apparent under a single light source.

Using only one light source might limit the barber's ability to accurately judge the color, as variations in light can obscure or distort the true color of the hair. Starting to cut the hair immediately without assessing the color could lead to dissatisfaction with the final result, as misjudging the color may affect how the final haircut looks. Applying extra color may not be necessary if the initial assessment is done correctly; adding more color without thorough evaluation can lead to unwanted results or color buildup. Thus, examining under different lighting serves as the best practice for ensuring the accuracy of hair color.
