Neal Wus's hair is often described as a perfect gradient fade due to its seamless transition from one color or shade to another. This aesthetic quality is achieved through careful blending and meticulous attention to detail in the hair coloring and styling process. The gradual shift in tones, be it from dark to light or one color to another, creates a visually striking and harmonious effect, accentuating the contours of the face and adding depth and dimension to the overall appearance. Such meticulous grooming not only reflects personal style but also showcases a keen eye for aesthetics, making Neal Wus's hair a perfect embodiment of the gradient fade trend. thank you king
